迭代目录中的特定文件

Question

我需要使用glob获取所有以“t_”开头的图像。我应该用什么模式来做这件事？

        //get any image files that begin with "t_" -- (t_image.jpg) not (image.jpg)
        $images = glob("" . $dir . "*.jpg");

        foreach($images as $image)
        {
            echo $image;
        }

Answer 1

foreach (glob("t_*.jpg") as $filename) {
    echo "$filename size " . filesize($filename) . "\n";
}

这意味着：

foreach (glob("$dir/t_*.jpg") as $filename) {
    echo "$filename size " . filesize($filename) . "\n";
}
