For a list of more appropriate places to ask for help using PHP, please visit http://www.php.net/support.php as this bug system is not the appropriate forum for asking support questions. Due to the volume of reports we can not explain in detail here why your report is not a bug. The support channels will be able to provide an explanation for you. Thank you for your interest in PHP. Your code is passing in an array, not a string. PHP itself did not change $str.

Test script: --------------- //a string is passed to the checkString protected function checkString($str) if(is_array($str)) { //only arrays allowed here but string goes into if var_dump($str);exit; //string enters here and $str becoumes a null array } else { echo 'ok'; } } result is array(0) { } Expected result: ---------------- protected function checkString($str) if(is_array($str)) { //only arrays allowed here but string goes into if var_dump($str);exit; //string enters here and $str becoumes a null array } else { echo 'ok'; } } result should be 'ok' Actual result: -------------- array(0) { } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71800&edit=1
