Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php You should not return string offsets by reference. In PHP 5.0 this would result in the following warning message: Fatal error: Only variables or references can be returned by reference Previous Comments: ------------------------------------------------------------------------ [2003-10-22 09:46:51] dand at codemonkey dot ro Sorry, the actual code producing the results above is: class Foo { var $hash; function & getElement($name) { return @$this->hash[$name]; } function bar($a, $b, $c) { print "BAR: $a, $b, $c<br>"; } } $f = new Foo(); for ($k = 0; $k < 3; $k++) { $t = $f->getElement($k); $f->bar(1, 2, 3); } ------------------------------------------------------------------------ [2003-10-22 09:43:40] dand at codemonkey dot ro Description: ------------ The code + results should be pretty self explainatory. A workaround would be to remove either the reference operator "& getElement" or the error suppression operator "@$this->hash". PS: I know that using @ instead of isset() is wrong, especially in this situation... Reproduce code: --------------- class Foo { var $hash; function & getElement($name) { return @$this->hash[$name]; } function bar($a, $b, $c, $d) { print "BAR: $a, $b, $c, $d<br>"; } } $f = new Foo(); for ($k = 0; $k < 3; $k++) { $t = $f->getElement($k); $f->bar(1, 2, 3, 4); } Expected result: ---------------- BAR: 1, 2, 3 BAR: 1, 2, 3 BAR: 1, 2, 3 Actual result: -------------- BAR: 1, 2, 3 BAR: 3, 3, 3 BAR: 3, 3, 3 [If it helps, in PHP 4.1.2 the actual result is: BAR: 3, 3, 3 BAR: 3, 3, 3 BAR: 3, 3, 3 ] ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=25951&edit=1
