Help explain strange explode behavior

Saeven

This script:

<?php

   $str = 'a,A:b,B';

   $arr = explode( ':', $str );

   echo '<pre>';
   print_r( $arr );
   echo '</pre>';

   foreach( $arr as $item ){
       list( $lower, $upper ) = explode( ',', $item );
       echo $lower . ', ' . $upper . '<br>';

   }
?>

Has a simple expected behavior of outputting the following:

Array
(
[0] => a,A
[1] => b,B
)

a, A
b, B

However, we've run into a system where it outputs as follows:

Array
(
[0] => a,A
[1] => b,B
)

Array,
Array,

Whilst I cannot explain it, I'm hoping that a member here can - I look forward to any suggestions! Baffled.

This exact script did this?
Or are you just using sudo-data?

I used this exact code and it works for me, so I'd expect something in yours has to be different than what's provided.

I copy and pasted your code snippet. Output looks fine.

<pre>Array
(
    [0] => a,A
    [1] => b,B
)
</pre>a, A<br>b, B<br>

Tested on php 4.2.2, 4.3.10, and 5.0.3.

Hi guys, it's exactly as posted above (inexplicable I agree). This particular machine, outputs as aforementioned without any discernable cause. I was hoping that someone would have an idea of some obscure setting etc.

The script is identical on both machines and what was quoted above, is veritable output, not pseudo-data.
