How can i escape double quotes from a string in php?

问题

I've been trying to solve this but no luck. This is my code.

       $replace1 =str_replace('hreflang=\"'.$arr['variantslang1hid'].'\"     lang=\"'.$arr['variantslang1hid'].'\"','hreflang=\"'.$arr['variantslang1'].'\" lang=\"'.$arr['variantslang1'].'\"',$replace1);

It should replace but no. I'm not escaping "" properly. How can i solve this? Help much appreciated!

if you use single quotes, you don't need to escape double quotes, '"' is what you want.
