#21287 [Opn->Bgs]: str_replace behaves strangely, not replacing valid key/val pairs

ID: 21287 Updated by: black@php.net Reported By: tit.petric@telemach.net -Status: Open +Status: Bogus Bug Type: *General Issues Operating System: linux debian -PHP Version: 4.2.3 +PHP Version: 4.3 New Comment: it appears i had a nested template to replace a key, after the key/value pairs were substituted already - thus resulting in that little error totally my fault, seems that most of my bugs are :P Previous Comments: ------------------------------------------------------------------------ [2002-12-30 10:56:59] tit.petric@telemach.net behaviour confirmed also on 4.3 http://sunshine.krneki.org/phpinfo.php i've tried the script with and without the phpA zend_extension, and if it was active then i tried it in disabled mode (php_value phpa off - inside .htaccess) currentlly the php.ini file is the same as php.ini-recommended inside the 4.3.0 distribution i now definetly check if i str_replace that key inside the first loop and the logging is as follows (same as before): (1.228) 0.0028 replace block_spacing_height => <img src="modules/themes/base/images/pixel.gif" align="middle" border="0" alt="" height="10"> (1.232) 0.0040 block_spacing_height exists in parsevals?!?!? (1.233) 0.0017 Undefined variables exist in root (site_footer.tpl): Array ( [0] => Array ( [0] => {block_spacing_height} ) ) ofcourse after the repeated str_replace the key is accurately replaced so i dont know where the problem could live (if its on my side)... is there any way i can track this more accuratelly than with my own functions? debug_backtrace() perhaps? ------------------------------------------------------------------------ [2002-12-30 06:00:42] tit.petric@telemach.net i have a template engine running, in it a string (content hereon) with keys and an array (parsevals hereon) with key/values that need to be replaced in the content this is what i do: foreach ($this->_parsevals as $key=>$val) { $retval = str_replace('{'.$key.'}',$val,$retval); } after that i do a preg_match_all to find all the remaining keys in the content with this regexp: '/\{[A-Za-z][-_A-Za-z0-9]*\}/', and find existing keys, which also exist in $this->_parsevals.. if (preg_match_all($this->regex_var,$retval,$result)) { foreach ($result[0] as $val) { $key = substr($val,1,-1); if (isset($this->_parsevals[$key])) { condor_assert($key." exists in parsevals?!?!?"); $retval = str_replace($val, $this->_parsevals[$key],$retval); } } } condor_assert is a basic log function, and its activated with that error message in there... another str_replace seems to solve the problem of the "undefined variable" case.. i tried to reproduce this in a short-self-contained script but failed, i will test it on 4.3 asap ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=21287&edit=1
