Delete first 3 characters and last 3 characters from String PHP

Question

I need to delete the first 3 letters of a string and the last 3 letters of a string. I know I can use substr() to start at a certain character but if I need to strip both first and last characters i'm not sure if I can actually use this. Any suggestions?

Answer 1

Pass a negative value as the length argument (the 3rd argument) to substr(), like:

$result = substr($string, 3, -3); 

So this:

<?php $string = "Sean Bright"; $string = substr($string, 3, -3); echo $string; ?> 

Outputs:

n Bri

Answer 2

Use

substr($var,1,-1) 

this will always get first and last without having to use strlen.

Example:

<?php     $input = ",a,b,d,e,f,";     $output = substr($input, 1, -1);     echo $output; ?> 

Output:

a,b,d,e,f
