How can escaping characters like quotes be used effectively in PHP code to prevent parsing errors?

To prevent parsing errors in PHP caused by characters like quotes, you can escape them using a backslash (\) before the character. This tells PHP to treat the character as a literal character rather than a special one that could interfere with the code execution. This is especially useful when dealing with strings that contain quotes or other special characters.

$name = "John O\'Connor";
echo $name;
