How to save binary image to local

I have a file getimage.php which it takes in a url and then provides a screenshot of the website:

header("Content-type: image/png");
echo($image);

which will print out an image if i reference it like this:

<img src="getimage.php?url=xxx.xom" />


Everything works fine, but I am thinking of saving this binary image locally. Is there a way to do that?

 

imagegif($png, './php.gif'); where $png is your image refference

good luck

 

or imagepng($imageSource, $imageFile, $compressionRate)
