[RESOLVED] explode .php file problem...

middleman666

hey people,

Im having a bit of trouble with the explode function or it could be the file_get_contents function, im a bit confused.

I have this code to explode a php file by ~ :

$filename = file_get_contents('content.php');
$entry_array = explode("~", $filename); 

echo $entry_array[1];
echo $entry_array[2];
echo $entry_array[3];
echo $entry_array[4];
echo $entry_array[5];

it then echos 5 of the entries.

In these entries taken from content.php is the following php:

<a href="?comments=ID2ndAugust121410#ID2ndAugust121410">comments</a>

<?php
    if ($_GET["comments"] == "ID2ndAugust121410") { 
    include ("comments/ID2ndAugust121410form.php");
    }
    else {}
    ?>

A link which should once clicked, include another php file, on the page that has exploded the contents.php file

Hope this is making sense...
My problem is that the php included in the exploded entries is not running when the link is clicked, i know theres nothing wrong with the php included in the entries as it works on its own. it is only when i explode to display only 5 entries that I get the problem.

Any ideas on how i could fix this?

Thanks.

The text you READ from a file, is interpreted as plain text input. Whereas when it is included as PhP it is PhP.

I think you would like to have a look at the eval function

Sorry about my newbieness, but I see no ~ signs in your content.php file.
I know explode() uses the first parameter as seperator, is ~ a special case?

middleman666

i havnt displayed the full content.php file, i ment to say that the second piece of code i showed Included the following code... sorry about that.
i assure you the ~ symbols are in there.

I will take a look at the eval function, thankyou.

middleman666

I tried this instead:

$filename = eval(file_get_contents('content.php'));

but then i get a parse error saying unexpected < in the contents.php file...

is there anything else you can suggest?

leatherback

Nope. Your PhP coding should be vaild.

But.. I have this urge to sugegst to rethink your design. Are you sure this is the best way to tackle your problem? Why do you need to explode code in a file? Why not save it as seperate files, or..??

middleman666

ugh, just wrote a long reply and then my machine went crazy.

ill just sum up my point...

i want to explode the content.php file which contains all the entries from a form.
i want to explode it so i can display just 5 entries from the file.
exploding is the only option i can think of as im quite new to php.
if you have any other suggestions apart from using a database then id really like to hear them 🙂

leatherback

I think you are really looking for an include. But I am not understanding the logic of what you are trying to achieve.
You are saving a form? Or the output? How is the code you posted in the first message related to a form? aahh

Confused.

middleman666

lol sorry, im not very good at explaining my actions (even i get confused at my reading my posts)

ok here it goes....

in my first post on this thread I did not include the whole of my script as its way too long and messy.

Ive made a flat file based site which allows users to add entries to the content.php file via a form.

These entries include tables, text, links, php, and thumbnails.

Each entry is writen to content.php at the top of the file before the other entries.

the php included in the entries is the code in my first post.

what im trying to do is make it so my main page (lets say main.php) displays only 5 of the entries from content.php.

the only way i can think of doing this is explode but that makes problems with the php included in each of the entries.

any other suggestions would be much appreciated 🙂

Antyrael

What if you put each entry in an array?
You can then use a do { ... } while loop to show the first 5 entries only.

middleman666

sounds interesting...

any chance you could post some sort of example code? as im not familiar with how that would work..

leatherback

along these lines:


$startcontent  = array(
0=>"<h1>This is a placemarker</h1> The owner of this page has not created content yet.
        If you have problems with editing the pages, please contact the webadministrator ($administror).",
1=>"<h1>This is a placemarker</h1> The owner of this page has not created content yet.
        If you have problems with editing the pages, please contact the webadministrator ($administror).",
2=>"<h1>This is a placemarker</h1> The owner of this page has not created content yet.
        If you have problems with editing the pages, please contact the webadministrator ($administror).",
3=>"<h1>This is a placemarker</h1> The owner of this page has not created content yet.
        If you have problems with editing the pages, please contact the webadministrator ($administror).",
4=> "<h1>This is a placemarker for your resume. </h1>
     The headers below are an indication of what you could include:
     <h2>Summary of Curriculum Vitae of YOURNAME</h2>
     (Place a short summary here)
     <h2>Academic Education</h2>
     (Your eduction here)
     <h2>Relevant Work Experience</h2>
     (your work experience)
     <h2>Publications:</h2>
     (your publicationlist goes here)
     <h2>Other Interests</h2>
     If you have problems with editing the pages, please contact the webadministrator ($administror)."
);

echo $startcontent[3];

middleman666

I see, Im pretty sure I understand that.

In theory, could I simply have the array as my content.php file and then include in my main.php and below the include echo the entries I wanted?

I would have to work out how to add the next number depending on what the last was and wouldn't I have to find a way of changing all the numbers so the newest entry is 1=> ?

how would I go about doing this? would I simply replace the numbers with variable like $number, and upon being loaded, the $number would increase by 1 everytime it was called upon?

leatherback

Hm..

You could add to the bottom of the file?
But.. The numbers do not need to be incremental top-> bottom. Unique, yes.

middleman666

but say if i had this on main.php:

// include array
include('content.php');

// display latest 5 posts
echo $startcontent[0]; 
echo $startcontent[1];
echo $startcontent[2];
echo $startcontent[3];
echo $startcontent[4];

then wouldn't I need to have the newest entry at the start of the array so it would become 0=>?

I know how I could get the newest entry to be written at the start of the array but im unsure of how to make the '$number' increase by 1 everytime its read.

do you know of a simple code to do this? is it something like count($number) or am i completly off target...?

leatherback

Hi,

I think it is time for you to have a little read in teh manual, and give things a bit of a try. I mean.. Trying to get you through every step of the process is not really helping you is there? What would you learn.. ?

You know aboput the good manual at php.net?

middleman666

fair enough.
yea i know about the manual, i do go there at times, but most the time i find myself not understanding it because of all the posts at the bottom of the pages, they confuse me because everyone has there own way of using one function.

I do feel I learn by seeing, because once you have a snipet of code, you can experiment with it and take it apart like 'what happens if I take this out' and the part that messes up is the part it controls and then i can take that part and stick it into something else and eventually ill have what i needed.

That may seem a stupid way of doing things to some people, but I feel it works best for me, at least at this early stage. im sure it a few years ill be saying what your saying.

cheers for all the help though, ill get searching and im sure ill be back here if it all goes horribly wrong 😉

cheers again!

leatherback

Hey Middleman,

Good luck, have fun and if you get stuck.. Usually theer are people here..

middleman666

hey people... well i say people, i mean leatherback,

Finnaly found out how to increase the array number by 1 as it is read from top to bottom.

this is so simple that your probly laughing at how i thought it was a bigger job..

<?php

$EntryNumber = 0;

$startcontent  = array( 

$EntryNumber++ => "Entry 0", 

$EntryNumber++ => "Entry 1", 

$EntryNumber++ => "Entry 2", 

$EntryNumber++ => "Entry 3", 

$EntryNumber++ => "Entry 4" 

); 

echo $startcontent[0];
echo '<br>'; 
echo $startcontent[1]; 
echo '<br>'; 
echo $startcontent[2]; 
echo '<br>'; 
echo $startcontent[3]; 
echo '<br>'; 
echo $startcontent[4]; 

?>

im about 90% sure this is what i can use to help me on my way... i was 100% 5mins ago, but now im confusing myself as to how the numbers will be set each time the file is written too.....

its in the back of my head somewhere so im sure ill work it out soon.

anyway, i think im resolved. so thanks for the input!

middleman666

to my anoyence (not sure if thats correct spelling), i get the same parse error when trying to read the php code from the array.

though my site works fine without having a certain number on each page, it would have been a nice thing to have insted of doing it manually, oh well. maybe one day ill find something that will do it, or ill be bothered to change my design.
