#49369 [NEW]: make current(),key(),next() etc. check for Iterator

From: admin at ifyouwantblood dot de Operating system: PHP version: 5.3.0 PHP Bug Type: Feature/Change Request Bug description: make current(),key(),next() etc. check for Iterator Description: ------------ it would be helpful for chained Iterators, if the default array functions would check if an given object is an instanceof Iterator and react appropriate. thus key() calling object->key(), current() calling object->current() and so on. Reproduce code: --------------- <?php class iterator_array implements Iterator { protected $aarray; public function __construct($array) { $this->aarray=$array; } public function key() { return key($this->aarray); } public function current() { return current($this->aarray); } public function valid() { return (current($this->aarray)!==FALSE); } public function next() { next($this->aarray); } public function rewind() { reset($this->aarray); } } $i=new iterator_array(Array(1,2)); var_dump(current($i)); var_dump(key($i)); next($i); var_dump($current($i)); var_dump(key($i)); Expected result: ---------------- int(1) int(0) int(2) int(1) Actual result: -------------- array(6) { [0]=> int(1) [1]=> int(2) [2]=> int(3) [3]=> int(4) [4]=> int(5) [5]=> int(6) } string(9) "&#65533;*&#65533;aarray" bool(false) NULL -- Edit bug report at http://bugs.php.net/?id=49369&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=49369&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=49369&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=49369&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=49369&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=49369&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=49369&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=49369&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=49369&r=needscript Try newer version: http://bugs.php.net/fix.php?id=49369&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=49369&r=support Expected behavior: http://bugs.php.net/fix.php?id=49369&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=49369&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=49369&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=49369&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=49369&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=49369&r=dst IIS Stability: http://bugs.php.net/fix.php?id=49369&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=49369&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=49369&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=49369&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=49369&r=mysqlcfg
