php curl、fopen、file_get_contents实例代码

//php curl实例代码如下:

session_write_close();
$pageurl = "http://www.phprm.com/index.html";
curl_setopt($ch, curlopt_returntransfer, 1);
curl_setopt ($ch, curlopt_url, $pageurl );
$html = curl_exec ( $ch );
curl_close($ch);
//then you need to fix pathing to absolute
$search = "/(src|href|background)="[^:,^>,^"]*"/i";
preg_match_all ( $search, $html, $a_matches );

//php fopen实例,代码如下:

$file = fopen("http://www.phprm.com/","r"); //读取远程文件
$file = fopen("a.txt","r");//读取本地文件
//php file_get_contents
$homepage = file_get_contents('http://www.phprm.com/'); //读取远程文本
echo $homepage;
:
// <= php 5
$file = file_get_contents(&#39;./people.txt&#39;, true);
// > php 5
$file = file_get_contents(&#39;./people.txt&#39;, file_use_include_path); //打开本地文本
