Example of a truncated use of string lengths in PHP

This article describes the use of string length interception in PHP. Share to everyone for your reference, as follows:

PHP provides a lot of usage functions, where the Intercept function of the string is no exception, and the function is very powerful.

<?php//file encoding format for utf-8$str= ' on the park boat, there's a pretty girl, if something happens in the middle of the lake ... '; Echo mb_substr ($str, 0,7, ' UTF-8 ');//Set the encoding format of the display string// Output ' on the park ship, there's ' Echo mb_substr ($str, 3,7, ' UTF-8 ');//Here Set the encoding format of the display string//output ' on board, there's a drift '?>

Here the coding format must be noted that improper handling may be garbled.

I hope this article is helpful to you in PHP programming.
