How does PHP handle the ending of a string when using different types of quotations?

When using different types of quotations in PHP (single quotes, double quotes, or heredoc/nowdoc syntax), the ending of a string can be handled differently. - Single quotes treat everything inside them as a literal string, so no special characters are interpreted, including escape sequences like \n or \t. - Double quotes allow for the interpretation of escape sequences and variables within the string. - Heredoc/nowdoc syntax can be used for multiline strings without the need for escaping special characters. 

// Single quotes
$string1 = 'This is a string with \'single quotes\' inside it.';

// Double quotes
$string2 = "This is a string with double quotes inside it: \"double quotes\".";

// Heredoc syntax
$string3 = <<<EOD
This is a heredoc string.
It can span multiple lines without needing to escape special characters or use concatenation.
