PHP封裝curl的呼叫介面及常用函數的介紹

今天为大家分享一篇PHP封装curl的调用接口及常用函数详解，具有很好的参考价值，希望对大家有所帮助。一起过来看看吧

如下所示：

<?php
	/**

	 */

		if($url == "" || $requestString == "" || $timeout <= 0){
			return false;
		}
		 $con = curl_init((string)$url);
	 curl_setopt($con, CURLOPT_HEADER, false);
	 curl_setopt($con, CURLOPT_POSTFIELDS, $requestString);
	 curl_setopt($con, CURLOPT_POST, true);
	 curl_setopt($con, CURLOPT_RETURNTRANSFER,true);
	 curl_setopt($con, CURLOPT_TIMEOUT, (int)$timeout);
		curl_setopt($con, CURLOPT_SSL_VERIFYPEER, false);
		curl_setopt($con, CURLOPT_SSL_VERIFYHOST, false);
	 return curl_exec($con);
	}
