<?php//What should I do if I want to display a double quote in the string of $beizi? $shengyang = 'i\'m xiaoshengyang';echo $shengyang;?>
Single quotes do not parse escape characters, why does 'i\'m xiaoshengyang' display i'm xiaoshengyang instead of \'m xiaoshengyang

Who told you that single quotes do not parse transfer characters?
Single quotes and the escape character itself can be escaped in a string defined by single quotes
