php method to obtain a substring based on the specified position and length, php string

The example in this article describes the method for php to obtain a substring based on the specified position and length. Share it with everyone for your reference. The specific analysis is as follows:

PHP’s substr function is very powerful. You can constantly remove substrings from front to back, and you can also take strings from back to front

<&#63;php
$string = "beginning";
print("Position counted from left: ".substr($string,0,5)."\n");
print("Position counted form right: ".substr($string,-7,3)."\n");
&#63;>

Output result:

Position counted from left: begin
Position counted form right: gin
