What is the significance of using different types of quotation marks in PHP code?

Using different types of quotation marks in PHP code can be significant when dealing with strings that contain quotes. By using a combination of single quotes ('), double quotes ("), and the heredoc or nowdoc syntax, you can easily handle strings that contain quotes without causing syntax errors. This allows for more flexibility and readability in your code. 

// Example of using different types of quotation marks in PHP code
$string1 = 'This is a string with single quotes';
$string2 = "This is a string with double quotes";
$string3 = <<<EOT
This is a string using heredoc syntax
It can contain 'single' and "double" quotes without issue
EOT;

echo $string1 . "\n";
echo $string2 . "\n";
echo $string3;
