From above code, I get the following output after I upload jpeg file:
Original file size: 7034
Compress file size: 7092
I really don't know why after I compress, it is increased? If I upload a large file size, the file size will reduce. When I upload a small file size, the file size is an increase. How should I do?

Here is my code of importing and converting a photo into database and in a path on server drive.
I want to upload multiple photos in database and convert all of them in a smaller size. For example when I press button "chose file" I want to select more than one photo , and submit all of them. After they need to go in my database, and to convert into a smaller size (all of them, not only one).

Thank you in advance.....
Change a bit for the input "file" element:
<input type="file" multiple name="file[]" id="file" accept="image/*" />
Its ok, now you can use $_FILES["file"]["name"][0] to get the name of 1st file, or _FILES["file"]["tmp_name"][1] to get the tmp_name of 2nd file, and so on.
I hope you understand, i cannot explain more because i am using phone...

You can use http://php.net/manual/en/function.imagefill.php starting at any point of background - probably 0,0 should be good. (If function is not found check if you have GD extension turned on.)
PHP - I am using this code to upload image file but i don't how to reduce the image file size but quality should be maintain .
$todir = 'members/'.$_SESSION[' valid_user '].'/';
$RandomNum = rand(0, 9999999999);
$info = explode('.', strtolower( $_FILES['Image']['name']) ); // whats the extension of the file
if(move_uploaded_file( $_FILES['Image']['tmp_name'], $todir . basename($_FILES['Image']['name']-$RandomNum) ) )
{
$handle= 'members/'.$_SESSION[' valid_user '].'/'.basename($_FILES['Image']['name']-$RandomNum);
echo 'uploaded';
}
Have you tried using ImageMagick to bring your images down to more appropriate sizes? (http://php.net/manual/en/imagick.setimagecompressionquality.php)
$name = "";
$type = "";

$error = "";

$image = imagecreatefromjpeg($source_url);
elseif ($info['mime'] == 'image/gif')
$image = imagecreatefromgif($source_url);
elseif ($info['mime'] == 'image/png')
$image = imagecreatefrompng($source_url);
imagejpeg($image, $destination_url, $quality);
return $destination_url;
}
if ($_POST) {
if ($_FILES["file"]["error"] > 0){
$error = $_FILES["file"]["error"];
} else if (($_FILES["file"]["type"] == "image/gif") || ($_FILES["file"]["type"] == "image/jpeg") || ($_FILES["file"]["type"] == "image/png") || ($_FILES["file"]["type"] == "image/pjpeg")){
$url = $_FILES["file"]["name"];
$filename = compress_image($_FILES["file"]["tmp_name"], $url, 30);
$buffer = file_get_contents($url);

I want to resize any image uploaded to 200*200 pixels.I have been looking over scripts all over the net,have found many but unable to use any.I don't want any other controls just resizing it to specific size.

if (!$i) { return ""; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);

<!--next comes the form, you must set the enctype to "multipart/frm-data" and use an input type "file" -->
<form name="newad" method="post" enctype="multipart/form-data" action="">

</form>
-->
Using PHP GD, instead of your code about copying the image from tmp_name to new_name use:
$image = file_get_contents($_FILES['image']['tmp_name']);
$new_image = imagecreatetruecolor(200, 200);
imagecopyresampled($new_image, $image, 0, 0, 0, 0, 200, 200, imagesx($image), imagesy($image));
file_put_contents($newname, $new_image);
