Regex question to match "\\"

[lonewolf217]

I am very new to regex and still very confused.

 

I am slowly learning from online tutorials but I cannot figure out how I can match double slashes "\\" like from a UNC path for a preg_replace

 

any help is appreciated

no need regex

if (  strpos($string,'\\') !==FALSE) {
   echo "found";
}

check the online PHP manual for string functions.

Well I know i can find it easily, but I am actually trying to do a preg_replace on it .. so i need regex.

 

perhaps I wasn't clear enough in my initial post.  I want to match the entire UNC string, which I think I can do on my own I just cannot figure out how to match the initial part of the double backslash

%\\\\\\\%

 

First you have to consider PHP's escaping rules, then the regex rules, which results in a double escaping effect.

try

<?php
$text = 'blah\\blah';
echo preg_replace('/\\\\/','xxx', $text);
?>
