FAQ:

[1] When creating a string, you can use single or double quotation marks to encapsulate characters. In addition, you must use the same type of quotation marks at the beginning and end of the character.

[2] If the same quotation marks appear in the middle of the string, you can use the problematic characters (the problematic character here is double quotation marks, and other problematic characters will be known later) put a backslash before it and escape it:

?

123	$var = "Define \"platitude\", please.";?>

Another way is to use single quotes (this way is to use single quotes when printing double quotes, and vice versa ):

?

123	$var = 'Define "platitude", please.'; ?>

1234	$book = 'High Fidelity'; $book = 'The Corrections'; ?>
