Edit report at https://bugs.php.net/bug.php?id=55157&edit=1 ID: 55157 Updated by: joey@php.net Reported by: olav at fwt dot no Summary: ArrayIterator::offsetUnset(); does not work correctly Status: Assigned Type: Bug Package: SPL related Operating System: openSUSE 11.4/Debian 5 PHP Version: Irrelevant Assigned To: colder Block user comment: N Private report: N New Comment: Just to narrow the scope of the bug a bit: $a = range( 0,9 ); $b = new ArrayIterator( $a ); foreach($b as $k=>$v) { $b->offsetUnset($k); } var_dump($b->getArrayCopy()); // why is 1 still around? Previous Comments: ------------------------------------------------------------------------ [2011-07-07 06:52:24] olav at fwt dot no Description: ------------ ArrayIterator always skips the second element in the array when calling offsetUnset(); on it while looping through. Using the key from iterator and unsetting in the actual ArrayObject works as expected. Running php 5.3.5 on openSUSE 11.4 Replicated same bug on Debian 5 running PHP 5.2.6-1+lenny9. php5 is installed as binary on both systems, SPL is builtin package. Test script: --------------- <?php // Create a array range from 0 to 9 $a = new ArrayObject( range( 0,9 ) ); $b = new ArrayIterator( $a ); for ( $b->rewind(); $b->valid(); $b->next() ) { echo "#{$b->current()} - \r\n"; $b->offsetUnset( $b->key() ); } ?> Expected result: ---------------- Expected a list of from 0 to 9 echoed out. Actual result: -------------- Lists out 0 and then 2-9 leaving index 1 untouched in the original ArrayObject. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=55157&edit=1
