note 69573 added to function.str-replace

CAUTION: This function will NOT do what you expect in many cases when you use arrays as both search and replace parameters. I found this out the hard way in a production website... Consider the following code: $a = "abcd"; $a = str_replace(array("a", "b", "c", "d"), array("albert ", "belinda ", "charlie ", "diana "), $a); echo $a; You would expect it to output "albert belinda charlie diana ", but it outputs: "albelindiana a ert belindiana a charlie diana " str_replace() simply executes itself for each array element, using the *already modified* string as input. This should be clearly noted in the manual. ---- Server IP: 212.124.37.9 Probable Submitter: 82.139.254.221 ---- Manual Page -- http://www.php.net/manual/en/function.str-replace.php Edit -- https://master.php.net/note/edit/69573 Del: integrated -- https://master.php.net/note/delete/69573/integrated Del: useless -- https://master.php.net/note/delete/69573/useless Del: bad code -- https://master.php.net/note/delete/69573/bad+code Del: spam -- https://master.php.net/note/delete/69573/spam Del: non-english -- https://master.php.net/note/delete/69573/non-english Del: in docs -- https://master.php.net/note/delete/69573/in+docs Del: other reasons-- https://master.php.net/note/delete/69573 Reject -- https://master.php.net/note/reject/69573 Search -- https://master.php.net/manage/user-notes.php
