"Translator" gets the length of the string in PHP (Strlen,mb_strlen)
Gets the length of the string.
Strlenint strlen (String str)

Parameters:
The string of the Str object

The number of bytes in the string
For the length of half-width text and full-width text, for example:
strlen (' abc ')--3strlen (' あいう ')--6strlen (' abcあいう ')--9
Instead of getting the number of bytes, instead of getting the number of words, use the [Mb_strlen] function. But half-width text is still full-width text,
are processed according to 1 text.
