Answers for "php foreach not looping, only using first element"

php foreach first element

foreach($array as $key => $element) {
    if ($key === array_key_first($array))
        echo 'FIRST ELEMENT!';

    if ($key === array_key_last($array))
        echo 'LAST ELEMENT!';
}

foreach loop not working in php

<?php
$songs = $_POST["songs"];
//$songs = Array("one","two","three");
foreach ($songs as $song) 
{
   $songStr = test_input($song);
   $songsOut .= "<li>$songStr</li>";
};

$songList = "Songs: <ol> $songsOut </ol> \r\n";
echo $songList;

function test_input($data)
{
   $data = trim($data);
   $data = stripslashes($data);
   $data = htmlspecialchars($data);
   return $data;
}

?>
