preg_replace not working for charachter \

Question

I'm trying to replace \' with ' but it won't work

This is the text I want to replace from

Using Twitter\'s @Anywhere Service in 6 Steps

and this is the code

$tutorial = "Using Twitter\'s @Anywhere Service in 6 Steps ";
echo $tutorial."<br /><br />";
$tut_title = preg_replace("/\\'/", "'", $tutorial);
echo $tut_title;
