quick function to replace ' with \' in php

Having a mental block....

I know this is开发者_如何学运维 so easy.... but nothing is going my way today!

Can anyone help me with a quick function to search a string and escape all apostrophes in php. Thanks.

You can use:

$changed_string = str_replace("'","\\'",$input_string)

You can also make use of the library function addslashes. Remember it will add slashes in front of single quote ('), double quote ("), backslash () and NULL.

Use str_replace:

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