Display onlyimages in adirectory

PHP
1

This script displays the contents of my directory, problem s it displays the strange directorie(., …)



<?php

$dirname = 'images/'.$row['user_id'].'/';
$images = scandir($thumbsdirname);
foreach($images as $curimg){
  echo "<a class='fancybox' href='".$dirname.$curimg."' data-fancybox-group='gallery' title='".$row['name']."'><img src='".$dirname.$curimg."' alt='' /></a>\
";
    }; 
?>

How do I change it to only display the image in the directory?

Thx

Got, had to create a array of accepted extensions, then I had to add an if statement to see if I either got a., a … or one other extension.


<?php

$thumbsdirname = 'images/'.$row['user_id'].'/thumbs/';
$dirname = 'images/'.$row['user_id'].'/';
$file_types = array ('jpg', 'jpeg', 'png', 'gif');
$images = scandir($thumbsdirname);
foreach($images as $curimg){
    $file_type = strtolower(end(explode('.', $curimg)));
    if ($curimg !=='.' && $curimg !== '..' && in_array($file_type, $file_types) == true)
    { 
echo ...
    }
    }; 
?>

A new way:

<?php

$directory = new DirectoryIterator(__DIR__);
$file_types = array ('jpg', 'jpeg', 'png', 'gif');
foreach ($directory as $fileinfo) {
    if ($fileinfo->isFile() && in_array($fileinfo->getExtension(), $file_types) ) {
        echo $fileinfo->getFilename() . "\
";
    }
}

?>
