this error.

So if If you wouldn't mind, could you show me exactly what I need right from
the beginning and explain why it works.
i.e.
if(preg_match(what goes here", $string)) {
Echo "You got it";
Beauford,
Because you're using forward slashes /.../ to delimit your pattern,
regexp is using the / in your character class to terminate your pattern:
/[EMAIL PROTECTED]&()*;:_.'/
Then it's looking at the subsequent characters as pattern modifiers
and gacking on the backslash. Even if you had a character there that
it could accept as a pattern modifier, the character class would be
incomplete (no closing bracket) so the pattern is doomed to fail.
You need to escape that forward slash in the character class:
preg_match("/[EMAIL PROTECTED]&()*;:_.'\/
Also, you've got only two backslashes in your char class. PHP is
reducing this to a single backslash before the space character. I
think you intend this to be two backslashes in the pattern so you
need four backslashes in PHP:
preg_match("/[EMAIL PROTECTED]&()*;:_.'\/\\\\ ]+$/", $string)
Regards,
Paul
