How can PHP developers properly escape or handle special characters within string literals to prevent syntax errors?

To properly escape special characters within string literals in PHP, developers can use the backslash (\) character before the special character to prevent syntax errors. This is particularly important when dealing with strings that contain quotes, backslashes, or other special characters that may interfere with the code execution.

// Example of properly escaping special characters within a string literal
$string = "This is a string with a quote: \" and a backslash: \\";
echo $string;
