摘要:
在这篇文章中主要讲解php_curl库的知识,并教你如何更好的使用php_curl。
简介
你可能在你的编写php脚本代码中会遇到这样的问题:怎么样才能从其他站点获取内容呢?这里有几个解决方式;最简单的就是在php中使用fopen()函数,但是fopen函数没有足够的参数来使用,比如当你想构建一个“网络爬虫”,想定义爬虫的客户端描述(ie,firefox),通过不同的请求方式来获取内容,比如post,get;等等这些需求是不可能用fopen()函数实现的。
为了解决我们上面提出的问题,我们可以使用php的扩展库-curl,这个扩展库通常是默认在安装包中的,你可以它来获取其他站点的内容,也可以来干别的。
备注:这两段代码需要php_curl扩展库的支持,查看phpinfo(),如果curl support enabled则表示支持curl库。
1、windows下的php开启curl库支持:
打开php.ini,将extension=php_curl.dll前的;号去掉。
2、linux下的php开启curl库支持:
编译php时在./configure后加上 –with-curl
在这篇文章中,我们一起来看看如何使用curl库,并看看它的其他用处,但是接下来,我们要从最基本的用法开始
基本用法:
第一步,我们通过函数curl_init()创建一个新的curl会话,代码如下:
// create a new curl resource
$ch = curl_init();
?>
我们已经成功创建了一个curl会话,如果需要获取一个url的内容,那么接下的一步,传递一个url给curl_setopt()函数,代码:
// set url and other appropriate options
curl_setopt($ch, curlopt_url, “http://www.google.com/”);
?>
