[php] endforeach in loops?

I use brackets when using foreach loops. What is endforeach for?

How about that?

<?php
    while($items = array_pop($lists)){
        echo "<ul>";
        foreach($items as $item){
            echo "<li>$item</li>";
        }
        echo "</ul>";
    }
?>

It's the end statement for the alternative syntax:

foreach ($foo as $bar) :
    ...
endforeach;

Useful to make code more readable if you're breaking out of PHP:

<?php foreach ($foo as $bar) : ?>
    <div ...>
        ...
    </div>
<?php endforeach; ?>

Using foreach: ... endforeach; does not only make things readable, it also makes least load for memory as introduced in PHP docs So for big apps, receiving many users this would be the best solution

How about this?

<ul>
<?php while ($items = array_pop($lists)) { ?>
    <ul>
    <?php foreach ($items as $item) { ?>
        <li><?= $item ?></li>
    <?php
    }//foreach
}//while ?>

We can still use the more widely-used braces and, at the same time, increase readability.

as an alternative syntax you can write foreach loops like so

foreach($arr as $item):
    //do stuff
endforeach;

This type of syntax is typically used when php is being used as a templating language as such

<?php foreach($arr as $item):?>
    <!--do stuff -->
<?php endforeach; ?>

It's just a different syntax. Instead of

foreach ($a as $v) {
    # ...
}

You could write this:

foreach ($a as $v):
    # ...
endforeach;

They will function exactly the same; it's just a matter of style. (Personally I have never seen anyone use the second form.)
