[3]php获取网页内容方法总结
    来源: 互联网  发布时间: 2013-11-30
抓取到的内容在通过正则表达式做一下过滤就得到了你想要的内容，至于如何用正则表达式过滤，在这里就不做介绍了，有兴趣的，以下就是几种常用的用php抓取网页中的内容的方法。
1.file_get_contents
PHP代码
代码如下:

<?php
$url = "http://www.";
$contents = file_get_contents($url);
//如果出现中文乱码使用下面代码
//$getcontent = iconv("gb2312", "utf-8",$contents);
echo $contents;
?>

2.curl
PHP代码
代码如下:

<?php
$url = "http://www.";
$ch = curl_init();
$timeout = 5;
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
//在需要用户检测的网页里需要增加下面两行
//curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_ANY);
//curl_setopt($ch, CURLOPT_USERPWD, US_NAME.":".US_PWD);
$contents = curl_exec($ch);
curl_close($ch);
echo $contents;
?>

3.fopen->fread->fclose
PHP代码
代码如下:

<?php
$handle = fopen ("http://www.", "rb");
$contents = "";
do {
$data = fread($handle, 1024);
if (strlen($data) == 0) {
break;
}
$contents .= $data;
} while(true);
fclose ($handle);
echo $contents;
?>

注：
1.使用file_get_contents和fopen必须空间开启allow_url_fopen。方法：编辑php.ini，设置allow_url_fopen = On，allow_url_fopen关闭时fopen和file_get_contents都不能打开远程文件。
2.使用curl必须空间开启curl。方法：windows下修改php.ini，将extension=php_curl.dll前面的分号去掉，而且需要拷贝ssleay32.dll和libeay32.dll到C:\WINDOWS\system32下；Linux下要安装curl扩展。
