PHP: Using glob() to list images

//path to directory to scan.
 $directory = "assets/images/thumbs/small/";
//get all image files with a .jpg extension.
 $images = glob("" . $directory . "*.jpg");
 $imgs = '';
// create array
 foreach($images as $image){ $imgs[] = "$image"; }
// sort by date if you like
//usort($imgs, create_function('$a,$b', 'return filemtime($a) - filemtime($b);'));
//sort by name
//usort($imgs, create_function('$a,$b', 'return strcmp($b, $a);'));
//display images
 foreach ($imgs as $img) {
   echo "<img src='$img' /> ";
 }

//path to directory to scan.

$directory = "assets/images/thumbs/small/";

//get all image files with a .jpg extension.

$images = glob("" . $directory . "*.jpg");

$imgs = '';

// create array

foreach($images as $image){ $imgs[] = "$image"; }

// sort by date if you like

//usort($imgs, create_function('$a,$b', 'return filemtime($a) - filemtime($b);'));

//sort by name

//usort($imgs, create_function('$a,$b', 'return strcmp($b, $a);'));

//display images

preg_replace for multidimensional arrays

Anybody trying to use preg_replace on multidimensional arrays will see that the function is not working for those cases. Here a quick workaround:

function preg_replace_array($pattern, $replacement, $subject, $limit=-1) {
    if (is_array($subject)) {
        foreach ($subject as &amp;$value) $value=preg_replace_array($pattern, $replacement, $value, $limit);
        return $subject;
    } else {
        return preg_replace($pattern, $replacement, $subject, $limit);
    } 
}

function preg_replace_array($pattern, $replacement, $subject, $limit=-1) {

if (is_array($subject)) {

foreach ($subject as &$value) $value=preg_replace_array($pattern, $replacement, $value, $limit);

return $subject;

} else {

return preg_replace($pattern, $replacement, $subject, $limit);

}
