Question

Write a program that reads 3 lines of input. On each line you get a single character. Combine all the characters into one string and print it on the console.

Examples:

Answer 1

<?php

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

echo $input1 . $input2 . $input3;

Answer 2

Another solution:

<?php

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

echo $result;
