PHP image width when the image is in a variable

I have loaded an image from database to a variable named $image.
How can I get the width of the image while it is stored in the variable?

The $image variable contains the data of the image. When I store the image, I just read it from the temp folder and write it to the database.

The accepted answer fulfills this question.
However, I am doing some resizing on the $im variable, so I need to reconvert it to string data, that can be done with the imagepng function.

If you have GD installed, you can just use something like $size = getimagesize($filename);

You could use imagecreatefromstring with imagesx.

Like:

$im = imagecreatefromstring($image);
if ($im !== false) {
    echo imagesx($im);
}
