Could someone explain to me why the loop isn’t working, it used to work and the agr to breaking the head without understanding anything, it seems not being interpreted I don’t know. The "hello world" above works, but when to interact with HTML PHP does not work.

<?='hello world'?>

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>Portal Noticias</title>
</head>
<body>
    <header>
        <div id="titulo">
            Portal Noticias
        </div>
    </header>

    <div id="noticias">
        <?for ($i=0; $i < 5; $i++) { ?>
            <article class="artigo">
                <h1>Titulo da noticia</h1>
                <p>
                    Lorem ipsum dolor sit amet, bla bla bla, consecetur. Lorem ipsum bla bla.
                </p>
            </article>
        <?}?> 

    </div>

</body>
</html>

  • Try to use <?php instead of <?.

I modified your code in PHP, so you can see the answer more easily. But nothing prevents you from using it your way. But to simplify the explanation, I put it as follows.

The tag <?php is the default for PHP file openings, unless Short Tag is enabled, which allows you to open PHP with <?. Already the tag <?= It’s quite simple what she wants instead of using <?php echo $variable; ?> just use <?=$variable?>. In order to make the code cleaner and readable. Reference: Sopt - juniorb2ss

You can see a little more about the language in: PHP

In order to be able to use this loop within your HTML, the following lines are required:

    <?php
        for ($i=0; $i < 5; $i++) { 
             echo '
                <article class="artigo">
                    <h1>Titulo da noticia</h1>
                    <p>
                        Lorem ipsum dolor sit amet, bla bla bla, consecetur. Lorem ipsum bla bla.
                    </p>
                </article>
            ';
       }
   ?>

Remember not to leave a space after <?php, this can result in future problems. It is also important to note that if the content is dynamic, it is of great importance that you use Xmlhttprequest.

    To complete, explaining that ?<?=? is just an abbreviation of ?<? php echo'. Leaves the code cleaner.
