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('./people.txt', true); 
// > php 5 
$file = file_get_contents('./people.txt', file_use_include_path); //打开本地文本
