If you just want to do string replaces:

preg_replace("\\", "\\\\", $string);

Notice that the \ is a special character and has to be escaped!

However, if you're interested in escaping strings, PHP has some built-in functions to do that:

See the addslashes function:

addslashes($string);

Um... Same as any other string?

$out = str_replace("\\","\\\\",$in);

The only difference is that you have to escape each \ in the string.

Use str_replace:

str_replace('/', '//', 'abc/def/xyz');

OUTPUT:

abc//def//xyz
