PHP从文件夹中回显几个<img>

Question

So I basically have this code:

<?php
    $lang = isset($_GET['lang']) ? $_GET['lang'] : NULL;
    $langArray = array('en', 'de', 'fr', 'es', 'it');

    $img = "<img src='img/".$lang."/1.png' />";
?>

[some useless code here...]

<div class="col ">
    <?php echo $img; ?>
    <p>Here some text under the img</p>
</div>

It will display a different image depending on the language chosen. As you can see, the image is stored in a folder with the name of the language. For example, if you choose 'en' for english, the picture display will be /img/en/1.png.

My problem is that I have multiple pictures in these folders (1.png, 2.png... 5.png). Instead of writing this :

<?php
    $lang = isset($_GET['lang']) ? $_GET['lang'] : NULL;
    $langArray = array('en', 'de', 'fr', 'es', 'it');

    $img = "<img src='img/".$lang."/1.png' />";
    $img = "<img src='img/".$lang."/2.png' />";
    $img = "<img src='img/".$lang."/3.png' />";
    $img = "<img src='img/".$lang."/4.png' />";
    $img = "<img src='img/".$lang."/5.png' />";

?>

Is there a way to echo these pictures with a loop? I'm new to PHP and not sure of what I should write.

Thanks.

Answer 1

You can use loops in html like so

<?php for($i = 1; $i <= 5; $i++): ?>
    <img src="img/<?= $lang ?>/<?= $i ?>.png" />
<?php endfor; ?>

<?= is short from <?php echo
