Re: preg match compilation error

Do you realy want to use [ and ] as patern delimiters? My quess is that you want to use it for defining character class. Then the only character that must be escaped is - '/[^a-z0-9,._+()\-]/i' Luis Lebron wrote:

I found a reqular expresion that I'm using to check for valid characters in file names. Here's the sample code: if(preg_match("[^a-zA-Z0-9,._\+\()\-]",$filename)) { //blah, blah, blah } However, when I run the script I get the following error: Warning: Compilation failed: unmatched parentheses at offset 17 in /home/httpd/sigmarapid/html/test/upload.php on line 137 (the line with the preg_match) I'm new to regular expressions so any help would be greatly appreciated.
