To get the length of a string in PHP, use the strlen($string) built-in function. The strlen() takes a string as an argument and returns the length of the string. The strlen() function returns the number of bytes, not characters. If your string contains Unicode characters, strlen() will return a string length bigger than the number of visible characters since Unicode characters are represented in PHP as 2 bytes. To get the number of visible characters, use the mb_strlen($string, 'utf8') function instead of strlen(). Recent versions of PHP have significantly improved the performance of the strlen() function. Multiple strlen() calls for long PHP strings are almost as fast as a single call. In this PHP String Length example, we use the strlen() function to get the length of an ASCII string (without Unicode characters).
