<script[\s\S]*?/script> this is my expresion
when i used it with preg_replace to remove the tag it gave me this error
Warning: preg_replace() [function.preg-replace]: Unknown modifier 'c' in C:\xampp\htdocs\get_page.php on line 21
can anyone help me
thanks
You should choose a suitable delimiter for your regular expression (preferably one that doesn't' occur anywhere in your pattern, so that you don't need to escape). For example:
"#<script[\s\S]*?/script>#"
Also, don't do that if you are trying to prevent malicious people from injecting Javascript into your page. It can easily be worked around. Use a whitelist of known safe constructs rather than trying to remove dangerous code.
PHP requires delimiters on RegExp patterns. Also, your expression can be simplified.
|<script.+/script>|
Did you wrap your regexp in forward slashes?
$str = preg_replace('/<script[\s\S]*?\/script>/', ...);
Did you surround your regular expression with a delimiter, such as /? If you didn't, you need to. If you did, and you used / (as opposed to your other choices) you'll need to escape the / in your /script, so it'll look like \/script instead.
Use the following code :
$result = preg_replace('%<script[\s\S]*?/script>%', $change_to, $subject);
