Question

why here str_replace not working

<?php
$str= '<div class=\"droppable\" ondrop=\"drop(event)\" ondragover=\"allowDrop(event)\"></div>';
echo str_replace('\"','"', $str);

i want to use str_replace with HTML tag.

Answer 1

As I get you want to remove the \ s to get proper HTML.

Better way should be -

stripslashes('<div class=\"droppable\" ondrop=\"drop(event)\" ondragover=\"allowDrop(event)\"></div>');

Output

<div class="droppable" ondrop="drop(event)" ondragover="allowDrop(event)"></div>

stripslashes
