使用PHP计算特定子目录中的图像

<?php

function count_images($directory) {
    $image_extensions = array('jpg', 'jpeg', 'png', 'gif', 'bmp');
    $image_count = 0;

    if (is_dir($directory)) {
        $files = scandir($directory);
        foreach ($files as $file) {
            if (in_array(pathinfo($file, PATHINFO_EXTENSION), $image_extensions)) {
                $image_count++;
            }
        }
    }

    return $image_count;
}

$directory = 'path/to/your/directory';
$image_count = count_images($directory);

echo "There are {$image_count} images in the directory.";

?>
