Remove first and last character in string

Question

A question about php.

If I have variable named $string that contains the word "Testing" I would like the php code to delete the first and last character. (So the output would be "estin"). I've tried multiple functions for example str_replace and substr but so far I've only managed to delete only the first or only the last character.

I don't know how to delete both the first and last character.

if you delete the first and last character, the output must be 'estin' — david, Sep 27 '13 at 11:12

<?php
$str = 'Testing';
$result = substr($str, 1, -1);
echo $result; // estin

read more about: substr

function: substr can receive 3 parameters:

    string substr (string $string , int $start [, int $length ] )

If length is given and is negative, then that many characters will be omitted from the end of string (after the start position has been calculated when a start is negative). If start denotes the position of this truncation or beyond, false will be returned.

This is the right answer which gives option to replace a character and not just removing. – Hasnat Babur Jan 16 '20 at 17:43
