Simple question regarding preg_replace

[Guest upirate]

I allow my users to enter text through a text area in a variable called input

 

 

$text = preg_replace("/[^a-zA-Z0-9\-\s\$\.\(\)\]\[]/i", "", $input);

 

 

How can I include the newline character to be allowed in my preg_replace statement.

 

 

 

Thanks!!!

Maybe that topic's better for the RegEx board.

try to put an s to the end of the pattern

$text = preg_replace("/[^a-zA-Z0-9\-\s\$\.\(\)\]\[]/is", "", $input);

what does the s do ?

http://sg2.php.net/manual/en/reference.pcre.pattern.modifiers.php

 

s (PCRE_DOTALL)

    If this modifier is set, a dot metacharacter in the pattern matches all characters, including newlines. Without it, newlines are excluded. This modifier is equivalent to Perl's /s modifier. A negative class such as [^a] always matches a newline character, independent of the setting of this modifier.

thankyou for the post. I just have one last question to ask you and you seem like you can:

 

As I said before, I have this text area. I want the user to be able to cut and paste text from another site/document and for it to retain the paragraph and breaks. (but without any malicious tags etc)

 

 

do you know of any place where I can find the code ?

 

 

thanks again for the reply
