Previous Comments: ------------------------------------------------------------------------ [2003-06-06 10:00:07] c dot luxig at lmcsoft dot com Dynamic variables were not used in preg_replace(). I want searching html code for the tag "<usr my_var>" and want to replace this tag by the HTTP_POST or HTTP_GET var "my_var", but it doesn't work. Here is my regexp: $modified = '[...]<usr my_var>[...]'; $my_var = 'content'; $modified = preg_replace("/<usr\s+?(.*?)\s*?>/ims", ${"$1"}, $modified, -1); Output: [...][...] (replaced by empty string) This expression match to <usr my_var> and if i do the following preg_replace works correct: $modified = preg_replace("/<usr\s+?(.*?)\s*?>/ims", "$1", $modified, -1); Output: [...]my_var[...] And this also doesn't work: $modified = preg_replace("/<usr\s+?(.*?)\s*?>/ims", ${$my_var}, $modified, -1); Output: [...][...] (replaced by empty string) This is the problem. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=24061&edit=1
