What is the output of the following code? <?php $g = range(5,8); $h = array("a", "b", "c", "e"); for($i = 0; $i < count($g); $i++) { foreach ($h as $j) { echo $i.$j; break; } }

Code:

<?php
$g = range(5,8); // array [5,6,7,8]
$h = array("a", "b", "c", "e");
for($i = 0; $i < count($g); $i++) {
    foreach ($h as $j) {
        echo $i.$j;
        break;
    }
}

Explanation:

• Outer loop over $i from 0 to 3 (4 iterations)
• Inner foreach loop over array $h, but immediately break, so only the first iteration of the inner loop runs for each $i
• During each iteration, output is the concatenation of $i and $j, where $j is the first element of array $h, i.e., "a"

Final output:

0a1a2a3a

That is, for each $i, the output is "i" + "a" with no spaces.
