replace problem

pastet89

Hi!
I have a big problem from long time a go, and no idea how to solve it. I have a variable $html, coming from outside in my page, including a list of hours and some other things. What I want, is to get all the hours +2 (if it is 03:42 to have it 05:42). The only thing to work with, however, is the $html, because the hours come from outside. First, I tried this way:
$input_clock = array("00:", "01:", "02:", "03:","04:", "05:","06:","07:", "08:", "09:", "10:", "11:", "12:", "13:", "14:", "15:", "16:", "17:", "18:", "19:", "20:", "21:", "22:", "23:");
$output_clock = array("02:", "03:","04:", "05:","06:","07:", "08:", "09:", "10:", "11:", "12:", "13:", "14:", "15:", "16:", "17:", "18:", "19:", "20:", "21:", "22:", "23:", "00:", "01:");
$html = str_replace($input_clock, $output_clock, $html);

Then this:
$input_clock = array("/00:/", "/01:/", "/02:/", "/03:/","/04:/", "/05:/","/06:/","/07:/", "/08:/", "/09:/", "/10:/", "/11:/", "/12:/", "/13:/", "/14:/", "/15:/", "/16:/", "/17:/", "/18:/", "/19:/", "/20:/", "/21:/", "/22:/", "/23:/");
$output_clock = array("02:", "03:","04:", "05:","06:","07:", "08:", "09:", "10:", "11:", "12:", "13:", "14:", "15:", "16:", "17:", "18:", "19:", "20:", "21:", "22:", "23:", "00:", "01:");
$html = preg_replace($input_clock, $output_clock, $html);

But in both cases, if the hour is odd I finally get 00:00, and if it is even, I get 01:00, because I got stuck in an everlasting cycle:
For example: 19 -> 21-> 23 -> 01
or:
20 -> 22 -> 00
What am I supposed to do in this situation? Please, help me, if you can.

Here is what I came up with:

function timePlus2($time){
	$time += 2;
	$time = ($time > 23)? $time - 24: $time;
	$time = (strlen($time) < 2)? '0' . $time: $time;
	return $time;
}

$html = '23:42'; // modify this to set time
echo $html . '<br />'; // ouput set time
$html = preg_replace('#^(\d+)(:\d+)$#e', 'timePlus2("$1") . "$2"', $html);
echo $html; // ouput time + 2 hours

I'm not sure if there is any built-in time functionality within PHP that handles stuff like this, but from a regex standpoint, this may serve you well in what you are looking for.

Cheers,

NRG

use mktime($hour+2,$min,$sec,$month,$day,$year)

nrg_alpha,
thx, but where am I supposed to use this function? You have just defined it, but not use it anywhere in the code below... And also I can't understand how to set the time in the marked for that line. I mean, will I have to insert all the times from 00:01 to 23:59? Another one problem at the same line is:
$html = '23:42';
I thnk I cannot write this in the code, because $html contains many other ingredents.
THX

Edit:
NO, I did not fix it :queasy: It again goes in everlasing cycle... any ideas...?

pastet.. the function can be placed anywhere on the page, as it is called once the preg_replace statement is executed (have you even tried my code snippet as a test?).

And no, I have not just defined the function.. I use it; this line executes the function (function call is in bold):
$html = preg_replace('#^{(\d+)(:\d+)$#e',} 'timePlus2("$1") . "$2"', $html);

So you can keep the function just above the preg statement if you wish ( just like in my sample, for ease of location and reference if need be).

As for your $html variable, you can simply change the value of $html to a different time to test it. Change this line:

$html = '23:42'; // modify this to set time <-- see, I even included the comment about this.

You really need to read the comments provided and test the code. Just create a new php document and cut and paste my code into it , save it as something like 'test.php' and try it for yourself... Change the 23:42 to something else and see the results..

When you get the time variable from the other site, just plug that time variable into $html variable and away you go.. the preg_replace (in conjunction with the function) will automatically give you the time 2 hours away. This is pretty straightforward.

EDIT:
Ok, I re-read your initial post, and if I understand you correctly, your $html variable contains the list of times and such? If so, how are you supposed to get the time itself?

Nowhere in your original code does it show what the variable $html actually contains initially...

if $html is a simple single time such as say- 10:37, then you can simply plug this into my code snippet.. but if $html is a block of web code, I would need to see a sample of this... something tells me we would need to find and extract the time in the block of code first, assign it to a variable, and plug THAT into the code snippet.

Also, understand that my approach is completely different from yours. While you are trying to calculate each time which is offset by 2 hours (which I assume is so that you can simply pluck a given time by 2 hours ahead).. I am taking a single time and calculating that (instead of making some long array).

Perhaps I'm misunderstanding things here.

alpha,
I tried the code, but it again occured to go into everlasting cicle and display all odd as 00 and all evens as 01. The whole problem is, how to define the time itself into a variable, different from $html, because $html JUST CONTAINS the time. You may see the code here:
http://livescore-bg.net/www/index.txt
http://livescore-bg.net/www/clock.txt
http://livescore-bg.net/www/clock2.txt
and the appereance here:
http://livescore-bg.net/www
where .txt equals .php
What I want is to get on every $_GET['page'] different number for "2", because I want to get all the matches in my country time. But the problem is, that everyone of the is in its local time.
$vreme is the difference between my timezone and the timezone of the country of every match. "2" is for initial example, I will fix it later for every country.
When I set the time just to 15:00 for example, it got to 17:00 immediately. But when I inserted all the hours, (because in different days ocuur different hours it must be inserted all of them), it agai showed me 00:?? or 01:??.
I hope tis will help you to help and thanks a lot again.

To be honest, I'm not sure how much help I can be..Admittedly, your code is very hard to make out heads and tales..

I would start by making your included code a little more readable and streamlined:

clock.php:

$_GET['page'] = 'spain'; // obviously I added this just to see some results.. you would not use this line...
include("date.php");
$countryTimeDiff = array('england'=>'2','spain'=>'3','italy'=>'4','germany'=>'2');
if(!isset($_GET['page']) || is_null($_GET['page']) || $_GET['page'] == ''){
	$vreme = '0';
} else {
	foreach($countryTimeDiff as $key => $val){
		if($_GET['page'] == $key){
			$vreme = $val;
		}
	}
}
echo $vreme; // I just use this line to see the output.. do not use this line...

I only used four countries in the array which I arbitrarily called $countryTimeDiff.. you would need to add all the country names and their equivalent adjustments.

As a note on clock2.php...much like your initial clock.php code, it is long and bloated.. looks like it could be reduced in size by using a for loop statement..

I'm just not sure I can make much sense of it all, truth be told. I think I would need to know what exactly $html is equal to.. could you show me what that variable's value is? If the time you seek is in there, I might be able to help you find it.

[man]strtr[/man] will not replace parts of strings that had already been replaced.

$hours = array("00:", "01:", "02:", "03:", "04:"/*, ....*/);
$shifted_hours = $hours;
// Roll that by two elements.
array_push($shifted_hours, array_shift($shifted_hours));
array_push($shifted_hours, array_shift($shifted_hours));

// Make one array "00:"=>"02:" etc.
$hours = array_combine($hours, $shifted_hours);

// Now $hours can be used as the second argument to the second form of strtr()

pastet89

alpha, I think you saw also what $html contains at http://livescore-bg.net
it contains al the matces times goals and etc at the center of the page.

...weedpacket, Thanks I've tried your code like this:
$hours = array("00:", "01:", "02:", "03:","04:", "05:","06:","07:", "08:", "09:", "10:", "11:", "12:", "13:", "14:", "15:", "16:", "17:", "18:", "19:", "20:", "21:", "22:", "23:");
$shifted_hours = array("02:", "03:","04:", "05:","06:","07:", "08:", "09:", "10:", "11:", "12:", "13:", "14:", "15:", "16:", "17:", "18:", "19:", "20:", "21:", "22:", "23:", "00:", "01:");
// Roll that by two elements.
array_push($shifted_hours, array_shift($shifted_hours));
array_push($shifted_hours, array_shift($shifted_hours));

// Make one array "00:"=>"02:" etc.
$hours = array_combine($hours, $shifted_hours);
strtr($html, $hours);

but then I got on:
Fatal error: Call to undefined function: array_combine() in /home/www/livescore-bg.net/www/www/index.php on line 20
What to do, guys?

Edit: I finally made the array $hours myself i mean:
$hours = array(
"00:" => "02:",
"01:" => "03:",
"02:" => "04:",
"03:" => "05:",
"04:" => "06:", "05:" => "07:",
"06:" => "08:", "07:" => "09:",
"10:" => "12:",
"11:" => "13:",
"12:" => "14:", "13:" => "15:",
"14:" => "16:",
"15:" => "17:",
"16:" => "18:",
"17:" => "19:",
"18:" => "20:",
"19:" => "21:",
"20:" => "22:",
"21:" => "23:",
"22:" => "00:",
"23:" => "01:");

and then i wrote:
strtr($html, $hours);

I think that must have been the whole idea of your code, weddpacket, but nothing happened again. This time I did not get just 00: or 01:, but for real nothing happened as all the hours remained unchanged... :o Any ideas?

pastet89

Edit:
It took changes this time not 00: or 01: but with not +2 hours, but +8 Hours.
That is what it turned out:
13: -> 21:
16 -> 00
15 -> 23
21 -> 05 etc...
This is very strange...
I thought first that the big problem was, that 20 was going into 22, and 22 into 00, so all hours got in an everlasting cycle till the final point 00: or 01:, depending on what are they - odd or even.
But now, this is very very strange, why it turns them plus 8 hours? Any ideas?

What version of PHP are you running? When you get undefined function errors like that, this basically translates to either an extension not installed, or simply the version of PHP you are running does not have support for that particular function (even with the appropriate extension installed).

I would use the latest stable release version if possible (or at least match your live hosting provider's version (which really should be as new as possible...the current stable release is 5.2.6.. if your host is using a much older version.. perhaps consider switching to a host that uses an up-to-date version.. If you use the latest at home and use some functionality that is not supported by your online host, there could be issues).

Good call on the array shifting! Never dawned on me to think of that. Makes life quite easier, eh? 😉

pastet89

Can't youunderstand that the reason is not in the undefined function, because I prepared what it does myself... I put all the array 00 => =02, 01 => 03 in my code, but what I got was plus 8 but not 2 hours everywhere :eek: Any ideas why is that?

nrg_alpha

pastet.. if PHP is complaining about an undefined function (and you correctly typed in the function name), your version of PHP does not support it.

In your page, type:

echo phpinfo();

When you run the page, this will dump info regarding your PHP installation. What version is labeled at the top of this info?

You can then upload your page to your website and check out what version your webserver is using.

pastet89

nrg_alpha,
The prolem is not in my php support. It does not matter if even it doesn't support array_combine(), because what this function does, WAS DONE BY ME. array_combine() makes an array from this type:
array(
"a" => "b",

"d" => "r",

"4" => "dbf",

"fv" => "sdv");
etc. But I inserted that array in my code, so by now if this function works or not does not change the things anymore. The question is, why my hours go plu 8 but not with 2 hours forward?

You are using the return value from that function, right? It's not just

strtr($html, $hours);

but

$html = strtr($html, $hours);

isn't it?

And yes, array_combine() was introduced in PHP 5; in other words, over four years ago.

pastet89

weedpacket, I now that, and what exactly I did was:
$hours = array(
"00:" => "02:",
"01:" => "03:",
"02:" => "04:",
"03:" => "05:",
"04:" => "06:", "05:" => "07:",
"06:" => "08:", "07:" => "09:",
"07:" => "09:", "08:" => "10:",
"09:" => "11:",
"10:" => "12:",
"11:" => "13:",
"12:" => "14:", "13:" => "15:",
"14:" => "16:",
"15:" => "17:",
"16:" => "18:",
"17:" => "19:",
"18:" => "20:",
"19:" => "21:",
"20:" => "22:",
"21:" => "23:",
"22:" => "00:",
"23:" => "01:");

$html = strtr($html, $hours);
The strange thing is that I get every hour plus 8 forward, but not 2. That's very strange... Any other ideas? :queasy:

pastet89

I tried to make the array with one hour forward, and then I got all hours four hours forward. I did it plus 3, and I got it +12; I tried with +6 and I had no change. It seems that the script makes every hour x 4:
+1 = +4
+2 = +8
+3 = +12
+6 = 4x6 = 24 = no change...
😕:queasy: That's really strange... Someone to have any idea why is that?
