Question

I want to remove the backslash alone using php preg replace.

For example: I have a string looks like

$var = "This is the for \testing and i want to add the # and remove \slash alone from the given string";

How to remove the \ alone from the corresponding string using php preg_replace

Answer 1

why would you use preg_replace when str_replace is much easier.

$str = str_replace('\\', '', $str);

Answer 2

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

echo preg_replace('/\\\\/', '', $var);

Answer 3

You can also use stripslashes() like,

<?php echo stripslashes($var); ?>

Answer 4

$str = preg_replace('/\\\\(.?)/', '$1', $str);

Answer 5

This worked for me!!

preg_replace("/\//", "", $input_lines);
