How can you determine the length of a string in PHP?

To determine the length of a string in PHP, you can use the built-in `strlen()` function. This function takes a string as an argument and returns the number of characters in that string. You can simply pass the string you want to measure to `strlen()` to get its length. 

$string = "Hello, World!";
$length = strlen($string);
echo "The length of the string is: " . $length;
