PHP - foreach循環立即運行所有數組？

Question

我想循環一些函數循環與「foreach」和數組。但獲取信息需要很長時間。是否有可能同時運行所有數組循環元素？這裏

你的問題是消費擋在HTTP請求中的foreach的每次迭代的時間。這是API延遲的一個問題，它通常是通過同時處理HTTP請求的一部分來處理的。

例如，如果每個HTTP請求需要3秒鐘即可完成，並可以同時處理10個HTTP請求，那麼你就做你的腳本大致快10倍

100 Requests w/o concurrency (3 seconds each, 1 at a time) = 300 seconds 
100 Requests w/ concurrency (3 seconds each, 10 at a time) = 30 seconds 

有一個漂亮的並行化HTTP請求的最佳方式是curl_multi*套功能。它建立在cURL庫上，它使用起來非常簡單。

教程：http://www.phpied.com/simultaneuos-http-requests-in-php-with-curl/

PHP手冊：http://php.net/manual/en/function.curl-multi-exec.php

重要的是要注意，有給你可以，也應該同時執行HTTP請求的數量真正極限是非常重要的。 curl_multi*默認爲10個併發HTTP請求，這是一個相當不錯的限制。增加此限制必須通過關心，尊重和責任它可以對其他服務造成嚴重損害。

爲了增加此限制（例如，如果你對自己的服務器發出請求），可以使用curl_multi_setopt與CURLMOPT_MAXCONNECTS選項

$new_limit = 15; 
curl_multi_setopt ($mh, CURLMOPT_MAXCONNECTS, $new_limit); 

另外請注意，您可以不使單個請求往前走比它已經做得更快，除非你的服務器/互聯網連接有問題。併發性不會幫助您提高個人請求速度（只是認爲我明確表示了這一點）。

您也可以使用線程，如果你喜歡，但我覺得內建的捲曲的方法將是最快，最簡單，最易於維護給您現有的代碼

在這種@edhurtig開始思想的同一行，你可能想看看PHP中的threading。我認爲你錯誤地指出了問題。你需要做幾個獨立的請求，他們不需要串行，這發生在一個foreach循環內。可以通過爲每個請求打開一個新線程來並行執行並行API調用。
