Description Christophe Saout 2004-12-16 05:45:58 UTC
The PHP 4.3.10 foreach function seems to have changed (probably not intentionally, the ChangeLog is speaking of "optimizations" backported from PHP 5).

$array = (
    0 => 'A',
    1 => 'B'
);

foreach($array as $bla) print_r($bla);

returns

Array(0 => 'A', 1 => 0)
Array(0 => 'B', 1 => 1)

instead of

'A'
'B'

This breaks pear (just try to run /usr/bin/pear) and TikiWiki, etc...


Reproducible: Always
Steps to Reproduce:
1. emerge php
2. run pear
3. watch the error messages

I assume you meant this as your test code:
------
$array = array(
    '0' => 'A',
    '1' => 'B'
);

foreach($array as $bla) print_r($bla);
------

And I do get the correct output of 'AB' on my x86 test box.

Could you please force the unpack+compile+package stages of the ebuild, then go into $S and run the PHP testcases?

Just recompiled. Same phenomenon. The test doesn't even begin.

Comment 4 Christophe Saout 2004-12-16 10:49:42 UTC
Ok, sorry.

When I disable the Zend Optimizer the problem goes away.

I looks like I need a newer version.

Sorry again.
