在php中替换\“with”

How to replace \" with " from a string in php and to remove \ from end of a string? My line of code is like :

$field[] = str_replace('\\"', '"', trim($val, '\\'));

But this is not working..somebody please help me

You can do it with default function - stripslashes:

$val = '"hell\"ooo\\';
echo stripslashes($val);

Or if you need with str_replace:

$val = '"hell\"ooo\\';
echo str_replace('\\"', '"', trim($val, '\\'));

Result would be:

"hell"ooo
