在php中复制BLOB类型的图像

I have a temporary path of an image in php in blob format that i want to copy to a different location on the server . But it is not working .

if(copy('blob:http://test.com/84d3e138-77d8-4169-a06e-86fbb3d434dc', 'destination/file.jpg'))
{
    echo "one";
}
else
{
    echo "two";
}

Any clue what am i doing wrong here
