error: Unknown modifier '='. What is the escape character in PHP?

[daydreamer]

I am trying to run this:

<?php
if(!preg_match("/^(([A-Za-z0-9!#$%&'*+/=?^_`{|}~-][A-Za-z0-9!#$%&'*+/=?^_`{|}~\.-]{0,63})|(\"[^(\\|\")]{0,62}\"))$/", $local_array[$i]))?>

 

And i get this:

Unknown modifier '='

 

Whats up here?!

 

thanks

First, it's not the correct forum. Second, it's caused because you have your delimiter in there (the character before the = which is a slash which is your delimiter). The delimiter is what tells preg_* that the actual regex is between those chars. You can use / # ~ @ ! . Those are all that I saw once, possibly there's more, I don't know. The escape char is backslash \ so replacing / with \/ should do the trick. Same goes for all occurrences in your regex except the last one of the string obviously.
