Description:
------------
Tested with: 5.2.6(win), 5.2.9(win) and 5.2.9-0.dotdeb.2 (lin).
Writing a value of a SimpleXML-Element in a foreach loop, causes PHP to
never leave the foreach loop, if you access that element via an extra
index.
Reproduce code:
---------------
error_reporting(E_ALL);
$xmlData = '<root><child><name>A
child</name><info><version>1</version></info></child><child><name>B
child</name><info><version>2</version></info></child><child><name>C
child</name><info><version>2</version></info></child><child><name>D
child</name><info><version>3</version></info></child></root>';
$xml = simplexml_load_string($xmlData);
$i = -1;
foreach ($xml as $xi => $child) {
++$i;
$xml->child[$i]->info->version = rand(1,9);
echo 'I: '.$i.' Xi: '.$xi.' Count : '.count($xml).'
'.$xml->child[$i]->name.' => '.$child->name.'
v:'.$child->info->version."\n";
if($i > 10) {
echo "Too many iterations";
break;
}
}
// Code below works as expected
$xml = simplexml_load_string($xmlData);
for($i = 0, $size = count($xml); $i < $size; ++$i) {
echo 'I: '.$i.' Count : '.count($xml).'
'.$xml->child[$i]->name."\n";
$xml->child[$i]->info->version = rand(1,9);
}
Expected result:
----------------
Something like that:
I: 0 Xi: child Count : 4 A child => A child v:1
I: 1 Xi: child Count : 4 B child => B child v:3
I: 2 Xi: child Count : 4 C child => C child v:3
I: 3 Xi: child Count : 4 D child => D child v:7
I: 0 Count : 4 A child
I: 1 Count : 4 B child
I: 2 Count : 4 C child
I: 3 Count : 4 D child
Actual result:
--------------
I: 1 Xi: child Count : 4 B child => B child v:6
I: 2 Xi: child Count : 4 C child => B child v:6
I: 3 Xi: child Count : 4 D child => B child v:6
I: 4 Xi: child Count : 5 => B child v:6
I: 5 Xi: child Count : 6 => B child v:6
I: 6 Xi: child Count : 7 => B child v:6
I: 7 Xi: child Count : 8 => B child v:6
I: 8 Xi: child Count : 9 => B child v:6
I: 9 Xi: child Count : 10 => B child v:6
I: 10 Xi: child Count : 11 => B child v:6
I: 11 Xi: child Count : 12 => B child v:6
Too many iterations
I: 0 Count : 4 A child
I: 1 Count : 4 B child
I: 2 Count : 4 C child
I: 3 Count : 4 D child
