problem with serialize

[lopann]

hi, im trying to save an all time high score and a daily high score for a flash game i made. the second score is the daily high that gets reset to zero each day. so heres the script that gets run daily...

<?php
// Read the file in
$oscores = file (scores/highscores.sco);

// Break out the data into a new 2-d array called $tscores
for ($i = 0; $i < 2; $i++)
{
$g = unserialize($oscores[$i]);
$tscores[$i][0] = $g[0];
$tscores[$i][1] = $g[1];
}
// Clear Second Score

	$tscores[1][0] = 0;
	$tscores[1][1] = "";

$file=fopen("scores/highscores.sco", "w");

// Write them out
for ($i = 0; $i < 2; $i++)
{
$st = serialize($tscores[$i]) . "\n";
fputs($file, $st);
}
fclose($file);
?>

the problem is that if i start out with an entry like this in my "highscores.sco" file...

a:2:{i:0;i:50;i:1;s:6:"gfdshh";}
a:2:{i:0;i:50;i:1;s:6:"gfdshh";}

i end up with this after the script runs...

a:2:{i:0;N;i:1;N;}
a:2:{i:0;i:0;i:1;s:0:"";}

as you can see the second score gets reset but it blows out the first score with the N's which isnt good. so my question is how do i make it keep the original first score intact? [ive tried only unserializing the second score to reset it and not touching the first score but when i put it back in it totally deletes the first score]
please help... thanks.

back to my original idea....

try this after reading the file....

for($i=0;$i<sizeof($oscores);$i++) //loop through main file array
{
     for($j=0;$j<sizeof($oscores[$i]);$j++) //loop through each array set
     {
               echo "oscores[$i][$j] = " .$oscores[$i][$j]. "<br>type = " .gettype($oscores[$i][$j]). "<br>sizeof = " .sizeof($oscores[$i][$j]). "<br><br>";
/* 
     the above line echo out the value of the indice, along with its
     data type, and size. each on its own line, labled and a blank
     line between each set
 */
     } //exit secondary array set
} //exit main file array loop

oke done editing that past... on another thought.... you could just read the FIRST line only, and then dump a blank array for the 2nd line to serialize... no point in trying to "read it" just to trash it.....

might eliminate the problem by sheer luck doing that. 😉

and and your serial data AFTER your script, the N's mean NULL data type... you can see this at http://www.orblivion.com/~tekky/serial.php

hi, thanks for the reply, i tried adding the echo but i still got the N's though.

also if i could just make it look something like this:

<?php
// Read the file in
$oscores = file (scores/highscores.sco);

	$g = unserialize($oscores[0]);

$file=fopen("scores/highscores.sco", "w");

// Write them out

	$st = serialize($g);
	fputs($file, $st);

	fclose($file);

?>

that would work ok too because i just want to save the first entry and blow out the second one. although when i run this i end up with:

b:0;

i really dont understand the unserialize function.

[tekky]

can you post what the loop outputed at the beginning of the file? (I want to see how its reading the data in)

in the mean time, I'll modify my page to show you what unserialize is doing 😉

alright check out http://www.orblivion.com/~tekky/serial.php again... unserialize()'s output is explained I hope in a simple method 😉

[lopann]

maybe, i dont understand the question but i think ive given all the information i have to offer. the .php script outputs

a:2:{i:0;N;i:1;N;}
a:2:{i:0;i:0;i:1;s:0:"";}

to the highscores.sco file

and if i use the second script it outputs

b:0;

theres nothing else in the file.

it sounds like theres something getting messed up in the file() function, is there any other way to read in data?

[tekky]

I posted you a loop, that goes AFTER $oscores = file(blahblah);

I posted that because I wanted the OUTPUT from that loop for debugging information..... that is the information you have not posted....

[lopann]

yes, you mean this? :

for($i=0;$i<sizeof($oscores);$i++)
{
for($j=0;$j<sizeof($oscores[$i]);$j++)array set
{
echo "oscores[$i][$j] = " .$oscores[$i][$j]. "<br>type = " .gettype($oscores[$i][$j]). "<br>sizeof = " .sizeof($oscores[$i][$j]). "<br><br>";
}}

i put it after the:
$oscores = file (scores/highscores.sco);

and it still outputs the exact same thing:
a:2:{i:0;N;i:1;N;}
a:2:{i:0;i:0;i:1;s:0:"";}

[tekky]

that means your data is getting read from the file wrong, if its trully stored in the file how you said earlier...

[lopann]

the weird thing is i have another .php script that also reads from the highscores.sco file the and outputs the data so flash can read it and its reading the scores fine. here's how it outputs to flash: (it reads the same as the other script)

if ($viewtype == "FLASH")
{
	for ($i = 0; $i < 3; $i++)
	{
		echo ("NAME" . $i . "=");
		echo ($tscores[$i][1]);
		echo ("&SCORE" . $i . "=");
		echo ($tscores[$i][0]);
		echo ("&");
	}
}

i doubt thats any help to you but thanks for your help.

[tekky]

hows it red into the the variable in that file though?

[lopann]

i figured it out!

this line-
$oscores = file (scores/highscores.sco);
should be
$oscores = file ("scores/highscores.sco");

i dont know why but the quotes make it read in correctly.
i cant thank you enough for your help though. i really appreciate it.

[tekky]

oh damn, yah, PHP requies STRINGS to be quoted in some form or fashion 😉

cant believe we missed that for that long

glad it works
