How can I use getimagesize() with $_FILES['']?

Question

I am doing an image upload handler and I would like it to detect the dimensions of the image that's been uploaded by the user.

So I start with:

if (isset($_FILES['image'])) etc....

and I have

list($width, $height) = getimagesize(...);

How am i supposed to use them together?

Thanks a lot

Answer 1

You can do this as such

$filename = $_FILES['image']['tmp_name'];
$size = getimagesize($filename);

// or

list($width, $height) = getimagesize($filename);
// USAGE:  echo $width; echo $height;

Using the condition combined, here is an example

if (isset($_FILES['image'])) {
    $filename = $_FILES['image']['tmp_name'];
    list($width, $height) = getimagesize($filename);
    echo $width; 
    echo $height;    
}

Try this for multi images :

for($i=0; $i < count($filenames); $i++){  

    $image_info = getimagesize($images['tmp_name'][$i]);
    $image_width  = $image_info[0];
    $image_height = $image_info[1];
}

Try this for single image :

$image_info = getimagesize($images['tmp_name']);
$image_width  = $image_info[0];
$image_height = $image_info[1];

at least it works for me.
