php - error 500 image base64 -


good day all, it's first time post here.

i want upload image in domain using image encoded base64, image uploaded server, i'm still getting server error 500, memory_limit @ php.ini file 128m`
i'm using xampp server 

    <?php  header('content-type : bitmap; charset=utf-8');  $encoded_string = $_post['string_encoded']; //encoded string  $imagename = 'image.png';  $decoded_string = base64_decode($encoded_string);  $path = 'imageses/'.$imagename;  $file = fopen($path, 'wb');  fwrite($file, $decoded_string); fclose($file);  ?>`

let's suppose image.png has size of 2mb. in case, decoding base64 write 64 * 2 mb memory, 128 mb. cause of issue. fix it, increase memory_limit in php.ini. possible problem can script loaded several times, doing same large decoding in parallel manner. if fails, can still achieve success, not decoding whole file, 1 smaller packet @ time , forgetting packet when calculated possible.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
