封裝getImageCreateFromData方法

public function getImageCreateFromData($qipa250_pic)
{
    //拆分，根據不同的檔案字尾判斷使用不同的生成圖片的函式
    $qipa250_pic_ay = getimagesize($qipa250_pic);
    $qipa250_pic_ay = explode('/'
 
, $qipa250_pic_ay['mime']);
    $qipa250_pic_postfix = $qipa250_pic_ay[1];
    switch ($qipa250_pic_postfix) {
        case 'jpg':
        case 'jpeg':
            $main = imagecreatefromjpeg($qipa250_pic);
            break;
        case 'gif':
            $main = imagecreatefromgif($qipa250_pic);
            break
 
;
        case 'png':
            $main = imagecreatefrompng($qipa250_pic);
            break;
    }
    return $main;
