If you want to remove backslash from text and don't want to see it anymore. then use this php function. But if it is a double backslash it will only remove one. stripslashes ($string)

You need to escape the backslash: \\

From the manual on preg_replace:

To use backslash in replacement, it must be doubled ("\\\\" PHP string).

Alternatively, use preg_quote to prepare a string for a preg_* operation.

This code works for me

  $text = "replace \ backslash";
  $rep = "";
  $replace_text = preg_replace( '/\\\\{1}/',$rep,$text);
  echo $replace_text;

Output :

replace backslash

You could try

$a = "\\\\";
$a = preg_replace('/\\\\/','/',$a);

Output:

'//'

Yes, but you need to escape it. When using it in the regexp use \\ to use it in the replacement, use \\\\ (that will turn into \\ that will be interpreted as a single backslash).

Escape \ with \: \\

preg_replace('/\\/', 'REMOVED BACKSLASH', 'sometest\othertest');
