Question

I have a function that would fetch a remote image via CURL, returning a string variable of the contents of the remote image.

I do not wish to write the content into the file, but wish to get the size of the image.

since getimagesize() only supports a file, is there a function similar to getimagesize() but can support strings of image content?

to clarify:

$image_content = file_get_contents('http://www.example.com/example.jpg');

how to get the image size of $image_content instead of running getimagesize('http://www.example.com/example.jpg');?

Thanks in advance

Answer 1

PHP functions imagecreatefromstring, imagesx, and imagesy.

Something like this;

$image_content = file_get_contents('http://www.example.com/example.jpg');
$image = imagecreatefromstring($image_content);
$width = imagesx($image);
$height = imagesy($image);
