note 102845 added to function.str-ireplace

Warning with highlighting ... I used : $text = preg_replace('/('.$q.')/i','<span class=highlighting "">$1</span>' , $text); Because this line do not allow to highlight uppercase and lowercase correctly (transform uppercase to lowercase for exemple) $text = str_ireplace( $q , '<span class=highlighting "">'.$q.'</span>', $text); But when $q contain some regex you have some problems ... for exemple : $q = '('; So you must use preg_replace to highlight correctly the text and you must create a function for escape bad regex caracters ! I think that a better function can be found but this works I guess : function regex_escape( $q ) { return preg_replace('/([\[\]\(\)\{\}\-\.\*\?\|\^\$])/', '\$1', $q); } ---- Server IP: 69.147.83.197 Probable Submitter: 87.91.6.54 ---- Manual Page -- http://www.php.net/manual/en/function.str-ireplace.php Edit -- https://master.php.net/note/edit/102845 Del: integrated -- https://master.php.net/note/delete/102845/integrated Del: useless -- https://master.php.net/note/delete/102845/useless Del: bad code -- https://master.php.net/note/delete/102845/bad+code Del: spam -- https://master.php.net/note/delete/102845/spam Del: non-english -- https://master.php.net/note/delete/102845/non-english Del: in docs -- https://master.php.net/note/delete/102845/in+docs Del: other reasons-- https://master.php.net/note/delete/102845 Reject -- https://master.php.net/note/reject/102845 Search -- https://master.php.net/manage/user-notes.php
