Question

I’m trying to replace / and \ with //:

$path = 'C:\wamp\www\mysite/bla/bla';
str_replace(array("\/", "\\"), array("\/\/", "\/\/"), $path);

but it doesn’t work:(

I get C:\\/wamp\\/www\mysite/bla/bla …

Answer 1

It is not necessary to escape the forward slash, so it is interfering with the pattern match.

Also, str_replace returns the replacement, it is not a byRef function so you’ll need to store the return in a variable (docs).

See it happen: http://codepad.org/CNr8P79m

<?php
$path = 'C:\wamp\www\mysite/bla/bla';
$path = str_replace(array("/", "\\"), array("//", "//"), $path);
echo $path;
// output: C://wamp//www//mysite//bla//bla

?>
