strlen()

Using the strlen()

The strlen() is used to find the length of a string.

Let’s find the length of our string “Hello world!”:

<?
echo strlen("Hello world!");
?>

The output of the code above will be:

12

The length of a string is often used in loops or other functions, when it is important to know when the string ends. (i.e. in a loop, we would want to stop the loop after the last character in the string)
