PHP how to save qr code generated in api.qrserver.com/v1/create-qr-code-CodePudding

I have been generated a qrcode in my php script and the output tag is something like this:

<img src="http://api.qrserver.com/v1/create-qr-code/?data=http://example.com/url321&amp;size=256x256&amp;color=000000&amp;bgcolor=ffffff&amp;margin=1px" alt="Scan QR-Code" title="Scan QR-Code" width="256px" height="256px">

Now, I want to save this generated image on my host How can I do this with PHP?

I tried this code but no success:

//This line generates qr code:
$qrsrc = 'http://api.qrserver.com/v1/create-qr-code/?data='.$url.'&amp;size='.$size.'&amp;color='.$color.'&amp;bgcolor='.$bgcolor;

//And the following lines try to store it:
$image_name = 'test.png';
$save_path = 'files/qrcode/'.$image_name;
$image_file = fopen($save_path, 'wb');
fwrite($image_file, $qrsrc);
fclose($image_file);

This code creates the image file. but image is not correct file... Thank you.

You're not actually fetching the image. You're just storing the literal URL as text in your test.png file.

First fetch the image:

$qrsrc = 'http://api.qrserver.com/v1/create-qr-code/?data='.$url.'&amp;size='.$size.'&amp;color='.$color.'&amp;bgcolor='.$bgcolor;
// Get the image and store it in a variable
$image = file_get_contents($qpsrc);   

// Save the file
$image_name = 'test.png';
$save_path = 'files/qrcode/'.$image_name;

// Save the image
file_put_contents($save_path, $image);

Note: To be able to fetch URL's using file_get_contents(), you need to make sure that you have allow_url_fopen enabled. Most installs I've used does already have it enabled as default.
You can read more about it in the manual
