Reverse a string with php

Question

I am trying to find a way to reverse a string, I\'ve seen alternatives but i wanted to to it this way thinking outside the box and not using anyone else\'s code as an altern

Answer 1

As others said, there's strrev() to do this.

If you want to build it on your own (for learning?): your problem is that you're starting with your index one too high - a string of length 25 is indexed from 0 to 24, so your loop has to look like this:

for ($i = $len - 1; $i >=0;$i--)
{
   echo $stringExp[$i];
}

Answer 2

You must get $len-1 because string starts from 0 to $len-1

Answer 3

<?php
// Reversed string and Number
//  For Example :
    $str = "hello world. This is john duvey";
    $number = 123456789;
    $newStr = strrev($str);
    $newBum = strrev($number);

    echo $newStr;
    echo "<br />";
    echo $newBum;

OUTPUT : first : yevud nhoj si sihT .dlrow olleh second: 987654321

Answer 4

for ($i = $len-1; $i >=0;$i--)
{
  echo $stringExp[$i];
}

Since the index starts at 0
