Replace one backslash with two backslash

[Anon]

I have the following line of code :

$tempString2 = ereg_replace("\", "\\", $string);

All I want to do is to parse a string and replace all sinlge backslashes () with two backslashes (\)

However, the code above gives me a Warning: REG_EPAREN error.

Anyone have any idea what I am doing wrong?

thanks...

I figured it out :

$tempString2 = ereg_replace("[]", "\\", $string);

That's a bad solution.

Generally, if you want to replace a specific character with other specific character(s) then use code like this:

<?php

$before='something';
$after=str_replace('e','eeeeee',$before);
print "<p>Before: '$before'; after: '$after'</p>";

?>

Regular expressions are nice - but much slower than a simple function like str_replace. So don't use regular expressions for simple cases.

By the way: It could sound like you are playing with something database related (and need to escape certain characters for your SQL query). If that's the case, then have a look at the fast and nice addslashes() function.
