note 70339 added to function.preg-replace

another note for newcomers to this function! you can use variables instead of absolute text when building your input text. however, this won't work: $input = "your name" . $_GET['name']; $in[0] = '/$input/'; $out[0] = "greetings friend!"; $new_contents = preg_replace($in, $out, $contents); - because the $input is interpreted literally, instead of being expanded. this will work (note the double quotes around $in[0]) $input = "your name " . $_GET['name']; $in[0] = "/$input/"; $out[0] = "greetings friend!"; $new_contents = preg_replace($in, $out, $contents); one more point, if you're using a / in your $input, you'll need to escape it e.g. if you have $input = "mysite/stuff/" . $_POST['filename']; you'll need to change it to $input = "mysite\/stuff\/" . $_POST['filename']; note: this is a very simple example, it probably wouldn't take much to break it and note note: there's a useful tutorial at http://www.tote-taste.de/X-Project/regex/printable.html ---- Server IP: 83.138.144.80 Probable Submitter: 217.23.234.66 ---- Manual Page -- http://www.php.net/manual/en/function.preg-replace.php Edit -- https://master.php.net/note/edit/70339 Del: integrated -- https://master.php.net/note/delete/70339/integrated Del: useless -- https://master.php.net/note/delete/70339/useless Del: bad code -- https://master.php.net/note/delete/70339/bad+code Del: spam -- https://master.php.net/note/delete/70339/spam Del: non-english -- https://master.php.net/note/delete/70339/non-english Del: in docs -- https://master.php.net/note/delete/70339/in+docs Del: other reasons-- https://master.php.net/note/delete/70339 Reject -- https://master.php.net/note/reject/70339 Search -- https://master.php.net/manage/user-notes.php
