Single and double quotation mark parsing escape character problem

Question

<?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

Answer 1

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
