Transferred from: http://blog.csdn.net/haha00217/article/details/7969504

Method 1: Use file_get_contents to get the content in the Get mode

 
 1 
   PHP  2$url= ' http://www.domain.com/';   3 $html file_get_contents ($url);   4 Echo $html ;   5 ?>  

Method 2: Open the URL with fopen and get the content in Get mode

 
 1 
   PHP  2$fpfopen($url, ' R ');   3 //

1 Stream_get_meta_data ($fp);  

1  while (! feof ($fp)) {  2$resultfgets($fp, 1024x768);   3 }  4echo$result";   5 fclose ($fp);   6 ?>  7  

Method 3: Use the file_get_contents function to get the URL by post

 
 1 
   PHP  2$dataarray (' foo ' = ' bar ');  

1 // generate Url-encode Request string, convert array to string   2 $data Http_build_query ($data);   3 $opts Array (    4array  (    5  6   7  Strlen($data). "\ r \ n",   8$data   9)  

1 // generate a handle file  for the request 2 $context stream_context_create ($opts);   3 $html file_get_contents false $context );   4 Echo $html ;   5 ?>  

Method 4: Open the URL with the Fsockopen function, get the complete data in Get mode, including header and Body,fsockopen need php.ini allow_url_fopen option to open

1 
 Php2 functionGet_url ($url,$cookie=false)  3 {  4 $url=Parse_url($url); 5 $query=$url[path]. "?".$url[query]; 6 Echo"Query:".$query; 7 $fp=Fsockopen($url[Host],$url[Port]?$url[Port]:80,$errno,$errstr, 30); 8 if(!$fp) {  9 return false; Ten}Else {   One $request= "GET$queryHttp/1.1\r\n ";  A $request. = "Host:$url[host]\r\n];  - $request. = "connection:close\r\n";  - if($cookie)$request. = "Cookie:$cookie\ n ";  the $request. = "\ r \ n";  - fwrite($fp,$request);  -  while()) {   - $result.= @fgets($fp, 1024);  + }   - fclose($fp);  + return $result;  A }   at }   - //gets the HTML part of the URL, removing the header - functionGeturlhtml ($url,$cookie=false)   - {   - $rowdata= Get_url ($url,$cookie);  - if($rowdata)   in {   - $body=Stristr($rowdata, "\r\n\r\n");  to $body=substr($body, 4,strlen($body));  + return $body;  - }   the     return false;  * }   $?>

Method 5: Use the Fsockopen function to open the URL, post to get the full data, including header and body

1 
 Php2 functionHttp_post ($URL,$data,$cookie,$referrer="")  3 {  4     //parsing the given URL5 $URL _info=Parse_url($URL); 6     //Building Referrer7 if($referrer=="")//if not given use this script as referrer8 $referrer= "111"; 9     //making string from $dataTen foreach($data  as $key=$value)   One $values[]="$key=".UrlEncode($value);  A $data _string=implode("&",$values);  -     //Find out which port was needed-if not given use standard (=80) - if(!isset($URL _info["Port"]))   the $URL _info["Port"]=80;  -     //Building Post-request: - $request. = "POST".$URL _info["Path"]. " Http/1.1\n ";  - $request. = "Host:".$URL _info["Host"]. " \ n ";  + $request. = "Referer:$referer\ n ";  - $request. = "content-type:application/x-www-form-urlencoded\n";  + $request. = "Content-length:".strlen($data _string)." \ n ";  A $request. = "Connection:close\n";  at     $request. = "Cookie:$cookie\ n ";  -     $request. = "\ n";  - $request.=$data _string." \ n ";  -     $fp=Fsockopen($URL _info["Host"],$URL _info["Port"]);  - fputs($fp,$request);  -  while(!feof($fp)) {   in $result.=fgets($fp, 1024);  - }   to fclose($fp);  +     return $result;  - }   the?>

Method 6: Using the Curl Library, before using the Curl Library, you may need to see if php.ini has the curl extension turned on

 
 1 
   PHP   2$ch = curl_init ();   3 $timeout = 5;   4 curl_setopt ($ch, Curlopt_url, ' http://www.domain.com/');   5 curl_setopt ($ch, Curlopt_returntransfer, 1);   6 curl_setopt ($ch$timeout);   7 $file _contents = curl_exec ($ch);   8 curl_close ($ch);   9 Echo $file _contents ;   Ten ?>
