I\'m trying to map some arrays values to an unordered () list.
function array2ul($array) {
$out = "<ul>";
foreach($array as $key => $elem){
if(!is_array($elem)){
$out .= "<li><span>" . $key . ": " . $elem . "</span></li>";
} else {
$out .= "<li><span>" . $key . "</span>" . array2ul($elem) . "</li>";
}
}
$out .= "</ul>";
return $out;
}
I'm not sure about this, but this might work:
<?php
$files = scandir($dir);
//remove "." and ".."
print_r($files);
?>
<ul>
<?php foreach($files as $file) { ?>
<li><?php echo $file; ?></li>
<?php } ?>
</ul>
That's what I would use, and if this doesn't work, it might be because your $dir
variable contains nothing (has an error). One reason why your original code might not have worked, because I don't think the <? ?>
tags are compatible on every server. Also, from what I know, there is no <?=$var ?>
thing in php. I thought it only exists in ASP and the like.
EDIT: In answer to your question about the inferiority of curly braces, they are the commonly accepted standard in PHP. This might be different in the C/C++/C# Family, I don't know.
replace <?= $file ?>
with <?php echo $file ?>
or enable your sort tags by php.ini ; it seems your server has not it enabled.
<?php foreach($files as $file): ?>
<li><?php echo $file ?></li>
<?php endforeach; ?>
OR
<?php foreach($files as $file): ?>
<li><? echo $file ?></li>
<?php endforeach; ?>
Used this today:
if ( !empty($files) ) echo '<li>' . implode('<li>', $files);
