Mine is with strrev string function (line #8):

<?php

$chars = '';
for ($i = 0; $i < 3; $i++) {
    $chars .= readline()." ";
}

echo strrev($chars);

My solution:

<?php

$input1 = readline();
$input2 = readline();
$input3 = readline();

echo "$input3 $input2 $input1";

Answer 3

Mine:

<?php

$chars = '';
for ($i = 0; $i < 3; $i++) {
    $chars .= readline();
}

$output = '';
for ($i = 2; $i >= 0; $i--) {
    $output .= $chars[$i] . " ";
}

echo $output;
