方法1: 用file_get_contents 以get方式获取内容

[php] view plaincopyprint?
  1. <?php  
  2. $url=‘http://www.domain.com/‘;  
  3. $html = file_get_contents($url);  
  4. echo $html;  
  5. ?>  
<?php$url=‘http://www.domain.com/‘;$html = file_get_contents($url);echo $html;?>

 

方法2: 用fopen打开url, 以get方式获取内容

[php] view plaincopyprint?
  1. <?php  
  2. $fp = fopen($url, ‘r‘);  
  3. //返回请求流信息（数组：请求状态，阻塞，返回值是否为空，返回值http头等）  
<?php$fp = fopen($url, ‘r‘);//返回请求流信息（数组：请求状态，阻塞，返回值是否为空，返回值http头等）
[php] view plaincopyprint?
  1. stream_get_meta_data($fp);  
stream_get_meta_data($fp);
[php] view plaincopyprint?
  1. while(!feof($fp)) {  
  2. $result .= fgets($fp, 1024);  
  3. }  
  4. echo "url body: $result";  
  5. fclose($fp);  
  6. ?>  
while(!feof($fp)) {$result .= fgets($fp, 1024);}echo "url body: $result";fclose($fp);?>

 

方法3：用file_get_contents函数,以post方式获取url

[php] view plaincopyprint?
  1. <?php  
  2. $data = array (‘foo‘ => ‘bar‘);  
<?php$data = http://www.mamicode.com/array (‘foo‘ => ‘bar‘);
[php] view plaincopyprint?
  1. //生成url-encode后的请求字符串，将数组转换为字符串  
  2. $data = http_build_query($data);  
  3. $opts = array (  
  4. <span style="white-space: pre;">    </span>‘http‘ => array (  
  5. <span style="white-space: pre;">        </span>‘method‘ => ‘POST‘,  
  6. <span style="white-space: pre;">        </span>‘header‘=> "Content-type: application/x-www-form-urlencoded\r\n" .  
  7. <span style="white-space: pre;">        </span>"Content-Length: " . strlen($data) . "\r\n",  
  8. <span style="white-space: pre;">        </span>‘content‘ => $data  
  9. <span style="white-space: pre;">    </span>)  
  10. );  
//生成url-encode后的请求字符串，将数组转换为字符串$data = http://www.mamicode.com/http_build_query($data);"white-space: pre;">	‘http‘ => array (		‘method‘ => ‘POST‘,		‘header‘=> "Content-type: application/x-www-form-urlencoded\r\n" .		"Content-Length: " . strlen($data) . "\r\n",		‘content‘ => $data	));
[php] view plaincopyprint?
  1. //生成请求的句柄文件  
  2. $context = stream_context_create($opts);  
  3. $html = file_get_contents(‘http://localhost/e/admin/test.html‘, false, $context);  
  4. echo $html;  
  5. ?>  
//生成请求的句柄文件$context = stream_context_create($opts);$html = file_get_contents(‘http://localhost/e/admin/test.html‘, false, $context);echo $html;?>

 

方法4：用fsockopen函数打开url，以get方式获取完整的数据，包括header和body,fsockopen需要 PHP.ini 中 allow_url_fopen 选项开启

[php] view plaincopyprint?
  1. <?php  
  2. function get_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;  
  10. } else {  
  11. $request = "GET $query HTTP/1.1\r\n";  
  12. $request .= "Host: $url[host]\r\n";  
  13. $request .= "Connection: Close\r\n";  
  14. if($cookie) $request.="Cookie:   $cookie\n";  
  15. $request.="\r\n";  
  16. fwrite($fp,$request);  
  17. while()) {  
  18. $result .= @fgets($fp, 1024);  
  19. }  
  20. fclose($fp);  
  21. return $result;  
  22. }  
  23. }  
  24. //获取url的html部分，去掉header  
  25. function GetUrlHTML($url,$cookie=false)  
  26. {  
  27. $rowdata = get_url($url,$cookie);  
  28. if($rowdata)  
  29. {  
  30. $body= stristr($rowdata,"\r\n\r\n");  
  31. $body=substr($body,4,strlen($body));  
  32. return $body;  
  33. }  
  34.     return false;  
  35. }  
  36. ?>  
<?phpfunction get_url ($url,$cookie=false){$url = parse_url($url);$query = $url[path]."?".$url[query];echo "Query:".$query;$fp = fsockopen( $url[host], $url[port]?$url[port]:80 , $errno, $errstr, 30);if (!$fp) {return false;} else {$request = "GET $query HTTP/1.1\r\n";$request .= "Host: $url[host]\r\n";$request .= "Connection: Close\r\n";if($cookie) $request.="Cookie:   $cookie\n";$request.="\r\n";fwrite($fp,$request);while()) {$result .= @fgets($fp, 1024);}fclose($fp);return $result;}}//获取url的html部分，去掉headerfunction GetUrlHTML($url,$cookie=false){$rowdata = http://www.mamicode.com/get_url($url,$cookie);"\r\n\r\n");$body=substr($body,4,strlen($body));return $body;}    return false;}?>

 

方法5：用fsockopen函数打开url，以POST方式获取完整的数据，包括header和body

[php] view plaincopyprint?
  1. <?php  
  2. function HTTP_Post($URL,$data,$cookie, $referrer="")  
  3. {  
  4.     // parsing the given URL  
  5. $URL_Info=parse_url($URL);  
  6.     // Building referrer  
  7. if($referrer=="") // if not given use this script as referrer  
  8. $referrer="111";  
  9.     // making string from $data  
  10. foreach($data as $key=>$value)  
  11. $values[]="$key=".urlencode($value);  
  12. $data_string=implode("&",$values);  
  13.     // Find out which port is needed - if not given use standard (=80)  
  14. if(!isset($URL_Info["port"]))  
  15. $URL_Info["port"]=80;  
  16.     // building POST-request:  
  17. $request.="POST ".$URL_Info["path"]." HTTP/1.1\n";  
  18. $request.="Host: ".$URL_Info["host"]."\n";  
  19. $request.="Referer: $referer\n";  
  20. $request.="Content-type: application/x-www-form-urlencoded\n";  
  21. $request.="Content-length: ".strlen($data_string)."\n";  
  22. $request.="Connection: close\n";  
  23.     $request.="Cookie:   $cookie\n";  
  24.     $request.="\n";  
  25. $request.=$data_string."\n";  
  26.     $fp = fsockopen($URL_Info["host"],$URL_Info["port"]);  
  27. fputs($fp, $request);  
  28. while(!feof($fp)) {  
  29. $result .= fgets($fp, 1024);  
  30. }  
  31. fclose($fp);  
  32.     return $result;  
  33. }  
  34. ?>  
<?phpfunction HTTP_Post($URL,$data,$cookie, $referrer=""){    // parsing the given URL$URL_Info=parse_url($URL);    // Building referrerif($referrer=="") // if not given use this script as referrer$referrer="111";    // making string from $dataforeach($data as $key=>$value)$values[]="$key=".urlencode($value);$data_string=implode("&",$values);    // Find out which port is needed - if not given use standard (=80)if(!isset($URL_Info["port"]))$URL_Info["port"]=80;    // building POST-request:$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";$request.="Connection: close\n";    $request.="Cookie:   $cookie\n";    $request.="\n";$request.=$data_string."\n";    $fp = fsockopen($URL_Info["host"],$URL_Info["port"]);fputs($fp, $request);while(!feof($fp)) {$result .= fgets($fp, 1024);}fclose($fp);    return $result;}?>

 

方法6:使用curl库，使用curl库之前，可能需要查看一下php.ini是否已经打开了curl扩展

[php] view plaincopyprint?
  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, CURLOPT_CONNECTTIMEOUT, $timeout);  
  7. $file_contents = curl_exec($ch);  
  8. curl_close($ch);  
  9. echo $file_contents;  
  10. ?>
