PHP は画像をアップロードしてサムネイルを生成します

 $details = getimagesize("$imageDirectory/$imageName") or die('画像のみをアップロードしてください.');
 $type = preg_replace('@^.+(?<=/)(.+)$@', '$1', $details['mime']);
 eval('$srcImg = imagecreatefrom'.$type.'("$imageDirectory/$imageName");');
 $thumbHeight = $details[1] * ($thumbWidth / $details[0]);
 $thumbImg = imagecreatetruecolor($thumbWidth, $thumbHeight);
 imagecopyresampled($thumbImg, $srcImg, 0, 0, 0, 0, $thumbWidth, $thumbHeight,
 $details[0], $details[1]);
 eval('image'.$type.'($thumbImg, "$thumbDirectory/$imageName"'.
 (($type=='jpeg')?', $quality':'').');' );
 imagedestroy($srcImg);
 imagedestroy($thumbImg);
}

foreach ($_FILES["pictures"]["error"] as $key => $error) {
 if ($error == UPLOAD_ERR_OK) {
 $tmp_name = $_FILES["pictures"][ "tmp_name"][$key];
 $name = $_FILES["写真"]["名前"][$key];
 move_uploaded_file($tmp_name, "データ/$name");
 createThumbnail("/メイン/画像の/場所/", $name, "/場所/ストア/サム", 120, 80);
 //120 = 親指の幅 :: 80 = 親指の品質 (1-100)
 }
}
