php - Can I use file_put_contents() to populate $_FILES? -


the goal:

i have url of image. image file , upload $_files if image uploaded client.

the reason:

i need because have form in users can either upload image file in input type="file" field or enter image url in input type="text" field , later, when validate form, want validation function access file using $_files regardless method user chose supply image (either uploading file or entering file url.)

the problem:

i found this answer on using file_put_contents() , file_get_contents() don't understand if can use change $_files , if yes how.

edit:

after reading david's comment, understood mistake. need way download file url using file_get_contents() , file_put_contents() same temporary location on server uploaded files downloaded to. able handle files same way regardless of how got there (url or file upload).

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
