In PHP, you can use the strlen function to get the length of a string. For example:

$str = "Hello, world!";
$length = strlen($str);
echo $length;

The output is:

13

Please note that the strlen function returns the number of bytes in a string, not the number of characters. For Unicode characters, you may need to use the mb_strlen function to calculate the number of characters.
