我有一个脚本;
$fileName = $_FILES['userfile']['name'];
$tmpName = $_FILES['userfile']['tmp_name'];
$fileSize = $_FILES['userfile']['size'];
$fileType = $_FILES['userfile']['type'];
// get the file extension first
$ext = substr(strrchr($fileName, "."), 1);
// make the random file name
$randName = md5(rand() * time());
// and now we have the unique file name for the upload file
$filePath = $imagesDir . $randName . '.' . $ext;
$result = move_uploaded_file($tmpName, $filePath);
if (!$result) {
echo "Error uploading file";
exit;
}
if(!get_magic_quotes_gpc()) {
$fileName = addslashes($fileName);
$filePath = addslashes($filePath);
}
用于上传图像,但我想添加一个脚本以在上传之前将图像调整为特定大小。我怎么做???
