    In PHP, the function used to determine the length of a string is strlen().

    Here's how you can use strlen() in PHP:

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

    In this example, strlen($string) returns the number of characters in $string. The output will be The length of the string is: 13, since "Hello, world!" is 13 characters long, including punctuation and spaces.

    strlen() is the most common and straightforward way to get the length of a string in PHP. There are no alternative standard PHP functions specifically for getting string length; strlen() is the go-to function for this purpose.
