The problem is the data pointer from the hash apply being overwritten in zval_copy_static_var() (Zend/zend_closures.c). The following patch works for me: http://spellign.com/patches/php-closure-ref-HEAD.patch Previous Comments: ------------------------------------------------------------------------ [2009-11-19 13:10:49] ninzya at inbox dot lv Description: ------------ See the reproduce code. I have a variable $ref, which is a reference to another variable. I am passing $ref to closure as use() by value, but, this kind of passing corrupts $ref variable after definition of closure and $ref becomes no longer reference, but points directly to copied data of $source variable, which $ref was previously referring to. However, if i define closure the following way: $closure =function() use( &$ref) {// note pass-by-reference echo $ref; }; the $ref does not loose it's state. Reproduce code: --------------- $source ='Dmitry'; $ref =&$source; $closure =function() use( $ref) { echo $ref; }; $ref ='Dmitry2'; echo $ref ."\n"; echo $source ."\n"; Expected result: ---------------- Dmitry2 Dmitry2 Actual result: -------------- Dmitry2 Dmitry ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=50230&edit=1
