PHP String Reverse

We can reverse any string by applying strrev function. Here is what a normal string will look like.

The string = This is a test

The new string after applying the strrev function is here

tset a si sihT

Here is the code

$st="This is a test";

echo "The string = ".$st."<br>";

$st=strrev($st);

echo "The new string after applying the strrev function = ".$st."<br>";
