How can escaping characters in PHP lead to syntax errors and how can this be avoided?

Escaping characters in PHP can lead to syntax errors when not done correctly, as it may interfere with the code structure. To avoid this issue, it is recommended to use functions like `addslashes()` or `mysqli_real_escape_string()` when dealing with user input to properly escape characters and prevent syntax errors. 

// Using mysqli_real_escape_string to escape characters in PHP
$input = "User's input with 'single' and \"double\" quotes";
$escaped_input = mysqli_real_escape_string($connection, $input);
