Problem with file_get_contents: failed to open stream: Operation now in progress

Question

PHP

Good evening.
There was a problem when working with the Simple HTML DOM Parser library.
When working in multiple threads (I use habrahabr.ru/post/134501/ ), the following error occasionally occurs:

PHP Warning:  file_get_contents(http://example.com): failed to open stream: Operation now in progress in /vendor/libraries/simplehtmldom/simple_html_dom. php on line 75

As I understand it, the problem here is the simultaneous launch of this function in different threads. Solution to only rewrite this part of the library using CURL?

Answer 1

For multi-threaded download - curl of course

Answer 2

instead try using
file_get_contents('http://example.com',false,stream_context_create());

Answer 3

Try using curl_multi_exec (and curl_multi_* in general ).
“Multithreading” is already implied there (specially indicated in quotation marks, because normal multithreading in PHP is still not implemented).
