file_put_contents file not uploading properly (file damaged or corrupted )

I have used following way to store file in public folder through api but file data damazed or corrupted

1st way:-

$filename="Pqr.pdf";

$resume="http://localhost/project_name/public/datafiles/APPL/Xyz.pdf"; //url link of 1st laravel project

file_put_contents(public_path('datafiles/APPL').'/'.$filename, fopen($resume, 'r')); //file upload in 2nd laravel project

2nd way:-

$filename="Pqr.pdf";

$resume="http://localhost/project_name/public/datafiles/APPL/Xyz.pdf";

file_put_contents(public_path('datafiles/APPL').'/'.$filename,file_get_contents($resume);

3rd way:-

$filename="Pqr.pdf";

$resume="http://localhost/project_name/public/datafiles/APPL/Xyz.pdf";

$data=file_get_contents($resume);

file_put_contents(public_path('datafiles/APPL').'/'.$filename,base64_decode($data));
