note 89139 added to function.str-replace

In order to create nicer urls i use this simple function: function niceURL($string) { $que = array( 'á','é','í','ó','ú','Á','É','Í','Ó','Ú','ñ','Ñ',' ' ); $por = array( 'a','e','i','o','u','A','E','I','O','U','n','n','-' ); return strtolower( str_replace( $que,$por,$string ) ); } For string "Hello Cruel World" This will return "hello-cruel-world" However once i wrote this: function niceURL($string) { //changing the place of ' ' by '-' to the begining $que = array( ' ','á','é','í','ó','ú','Á','É','Í','Ó','Ú','ñ','Ñ' ); $por = array( '-','a','e','i','o','u','A','E','I','O','U','n','n' ); return strtolower( str_replace( $que,$por,$string ) ); } And for "Hello Cruel World" This will return "hellocruelworld" I have no idea why but it made me crazy for a while, ---- Server IP: 69.147.83.197 Probable Submitter: 189.143.95.141 ---- Manual Page -- http://www.php.net/manual/en/function.str-replace.php Edit -- https://master.php.net/note/edit/89139 Del: integrated -- https://master.php.net/note/delete/89139/integrated Del: useless -- https://master.php.net/note/delete/89139/useless Del: bad code -- https://master.php.net/note/delete/89139/bad+code Del: spam -- https://master.php.net/note/delete/89139/spam Del: non-english -- https://master.php.net/note/delete/89139/non-english Del: in docs -- https://master.php.net/note/delete/89139/in+docs Del: other reasons-- https://master.php.net/note/delete/89139 Reject -- https://master.php.net/note/reject/89139 Search -- https://master.php.net/manage/user-notes.php
