How does PHP handle unexpected characters like commas in code execution?

PHP can handle unexpected characters like commas in code execution by using escape characters or enclosing the string containing commas in single or double quotes. This ensures that PHP interprets the comma as part of the string rather than a delimiter for separate arguments. 

// Using escape character to handle commas
$string = 'This string, contains a comma';
echo $string;

// Enclosing the string in double quotes
$string = "This string, contains a comma";
echo $string;
