PHP method to get image details


First we pass a parameter $filename of the image path, which is an absolute path


First we get the image size through the getimagesize method

//获取图片详细信息
function getImageInfo($filename){
    //$img为图像文件绝对路径
    $size = getimagesize($filename);
    switch ($img_info[2]) {
        case 1:
            $imgtype = "GIF";
            break;
        case 2:
            $imgtype = "JPG";
            break;
        case 3:
            $imgtype = "PNG";
            break;
    }
    $img_type = $imgtype . "图像";
    $img_size = ceil(filesize($filename) / 1000) . "k"; //获取文件大小
    $imgInfo = array(
        "width" => $size[0],
        "height" => $size[1],
        "type" => $img_type,
        "size" => $img_size
    );
    return $imgInfo;
}
Copy after login
