Comparing file_get_contents with curl and curl multi handlers
There is a way to handle multiple HTTP requests using curl. For comparison we will request contents of same url 100 times and for that we will use 3 different codes, one for file_get_contants, other for simple curl request and last for curl_multi request handling.
Here is a file_get_contents function:
<?php $domain = "http://code-snippets.co.cc"; for($i=0; $i<=100; $i++) { file_get_contents($domain); } ?>
Average results are 120 seconds or 1,2 seconds per request
Here is a simple curl request:
<?php $domain = "http://code-snippets.co.cc"; for($i=0; $i<=100; $i++) { $curl = curl_init(); curl_setopt($curl, CURLOPT_URL,$domain); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_exec($curl); curl_close($curl); } ?>
Average results are 100 seconds or 1 second per request
And here it is with multi curl handlers:
<?php $domain = "http://code-snippets.co.cc"; $curl_handlers = array(); for($i=0; $i<=100; $i++) { $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $domain); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); $curl_handlers[] = $curl; } $multi_curl_handler = curl_multi_init(); foreach($curl_handlers as $key => $curl) { curl_multi_add_handle($multi_curl_handler,$curl); } do { $multi_curl = curl_multi_exec($multi_curl_handler, $active); } while ($multi_curl == CURLM_CALL_MULTI_PERFORM || $active); foreach($curl_handlers as $curl) { curl_multi_getcontent($curl); } ?>
Average result is 21 second or 0,21 per request.
Conclusion: Curl multi handler is almost six times faster than file_get_contents and 5 times faster than simple curl request. So if you want to handle multiple HTTP requests do it using curl multiple request handler
