How can escaping characters be effectively implemented in PHP to prevent errors when manipulating strings?

When manipulating strings in PHP, it is important to escape characters to prevent errors, especially when dealing with special characters like quotes or slashes. One way to effectively implement escaping characters is by using functions like addslashes() or htmlspecialchars() to properly encode the string before manipulation. 

// Example of using addslashes() to escape characters in a string
$string = "This is a string with 'single' and \"double\" quotes.";
$escaped_string = addslashes($string);

echo $escaped_string;
