print_r causes white screen

[bftwofreak]

Hey guys, I'm having a strange issue, but whenever I use a print_r(); function it causes the entire page to fail and this is a page that is included in with several others.

<?php

$gameid = $_GET['gameid'];

I'm trying to figure out why $kills[2] is giving  me an array, but I can't figure out the keys unless I see the Array in a printable manner. Usually if there's something wrong with the script on this page, just this page fails where it is included as well as the script following it, but for some reason the entire page fails. Can anyone give a suggestion?

Add this to the top:

 

error_reporting(E_ALL | E_STRICT);

[bftwofreak]

nada... still shows up blank...

[xtopolis]

what about:

var_dump($kills[2]);

[bftwofreak]

tried it... same deal

[xtopolis]

So you're saying if you remove print_r.. the page works fine(aside from not getting the data you want)?  That doesn't make sense.

 

Also, all these tips should have given you something.  If you are using cURL, perhaps it's timing out?

[bftwofreak]

That's pretty much what happens... I'm not sure... I've tried the similar functions like var_dump(); and neither work. It causes the entire page to fail.

There might be HTML in the array which is being interpreted. Try

<?php
echo '<pre>' . print_r(array_map('htmlentities',$kills),true) . '</pre>';
?>

wow that worked for some reasons... I'm glad it worked, but I'm still wondering why...

[kenrbnsn]

It worked because htmlentities() turns characters like "<" into "&gt" which makes any HTML or Javascript in the array just strings and they won't be executed..
