How can one properly escape quotation marks in PHP to avoid syntax errors?

To properly escape quotation marks in PHP and avoid syntax errors, you can use the backslash (\) character before the quotation mark that you want to include as part of a string. This tells PHP to interpret the quotation mark as a literal character rather than as the end of the string.

// Example of escaping quotation marks in PHP
$string = "This is a string with \"escaped\" quotation marks";
echo $string;
