Several ways that PHP sends a GET, POST request

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. ?>

<?php$url= ' http://www.domain.com/'; $html = file_get_contents ($url); Echo $html; >

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

1. <?php
2. $fp = fopen ($url, ' R ');
3. Return request flow information (array: Request status, block, return value is empty, return value HTTP first)

<?PHP$FP = fopen ($url, ' r ');//Return request flow information (array: request state, block, return value is empty, return value HTTP first)

1. Stream_get_meta_data ($fp);

Stream_get_meta_data ($FP);

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);? >

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

1. <?php
2. $data = Array (' foo ' = ' bar ');

<?php$data = Array (' foo ' = ' bar ');

2. Generate Url-encode Request string, convert array to string
4. $data = Http_build_query ($data);
6. $opts = Array (
8. <span style="WHITE-SPACE:PRE;" > </span>' http ' = = Array (
10. <span style="WHITE-SPACE:PRE;" > </span>' method ' = ' POST ',
12. <span style="WHITE-SPACE:PRE;"  > </span>' header ' = ' content-type:application/x-www-form-urlencoded\r\n '.
14. <span style="WHITE-SPACE:PRE;" > </span>"content-length:". strlen ($data). "\ r \ n",
16. <span style="WHITE-SPACE:PRE;" > </span>' content ' = $data
18. <span style="WHITE-SPACE:PRE;" > </span>)
20. );

After generating the Url-encode request string, convert the array to a string $data = Http_build_query ($data); $opts = Array (the ' http ' = = Array ('method ' = > ' POST ',' header ' = ' content-type:application/x-www-form-urlencoded\r\n '." Content-length: ". Strlen ($data). "\ r \ n",' content ' = $data));

1. Generate a handle file for the request
2. $context = Stream_context_create ($opts);
3. $html = file_get_contents (' http://localhost/e/admin/test.html ', false, $context);
4. echo $html;
5. ?>

The handle file for the build request $context = Stream_context_create ($opts); $html = file_get_contents (' http://localhost/e/admin/test.html ', False, $context); Echo $html;? >

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

2. <?php
4. function Get_url ($url,$cookie =false)
6. {
8. $url = Parse_url ($url);
10. $query = $url [path]."?".  $url [query];
12. Echo "Query:".   $query;
14. $fp = fsockopen ( $url [host], $url [port]?   $url [port]:80, $errno, $errstr, 30);
16. if (! $FP) {
18. return false;
20. } Else {
22. $request = "GET $query http/1.1\r\n";
24. $request. = "Host: $url [host]\r\n";
26. $request. = "connection:close\r\n";
28. if ($cookie) $request. ="Cookie: $cookie \ n";
30. $request. ="\ r \ n";
32. Fwrite ($fp,$request);
34. while ()) {
36. $result. = @fgets ($fp, 1024);
38. }
40. Fclose ($fp);
42. return $result;
44. }
46. }
48. Gets the HTML part of the URL, removing the header
50. function geturlhtml ($url,$cookie =false)
52. {
54. $rowdata = Get_url ($url,$cookie);
56. if ($rowdata)
58. {
60. $body = stristr ($rowdata,"\r\n\r\n");
62. $body =substr ($body, 4,strlen ($body));
64. return $body;
66. }
68. return false;
70. }
72. ?>

<?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,); if (! $fp) { return false;} else {$request = "GET $query http/1.1\r\n"; $request. = "Host: $url [host]\r\n"; $request. = "connection:close\r\n"; if ($coo Kie) $request. = "Cookie:   $cookie \ n"; $request. = "\ r \ n"; fwrite ($fp, $request); while ()) {$result. = @fgets ($fp, 1024) ;} Fclose ($FP); return $result;}} Gets the HTML portion of the URL, removing headerfunction geturlhtml ($url, $cookie =false) {$rowdata = Get_url ($url, $cookie), or if ($rowdata) {$ Body= stristr ($rowdata, "\r\n\r\n"), $body =substr ($body, 4,strlen ($body)); return $body;}    return false;}? >

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

2. <?php
4. function Http_post ($URL,$data,$cookie, $referrer ="")
6. {

12. //Building referrer

20. foreach ($data as $key =$value)
22. $values []="$key =". UrlEncode ($value);
24. $data _string=implode ("&",$values);

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&NBSP;&NBSP;
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;
