In PHP to simulate POST request data submission we will use the CURL function, below I would like to give you a few Curl analog Post request submission data examples of friends who need to refer to.

Note: The curl function is not supported by default in PHP, if you need to use the Curl function we need to change the settings of your php.ini file to find Php_curl.dll to remove the previous ";" It's all right.

Example 1

The code is as follows

Copy Code

<?php $uri = "http://tanteng.duapp.com/test.php"; Parameter array $data = Array ( ' Name ' = ' Tanteng ' ' Password ' = ' password ' ); $ch = Curl_init (); Print_r ($ch); curl_setopt ($ch, Curlopt_url, $uri); curl_setopt ($ch, Curlopt_post, 1); curl_setopt ($ch, Curlopt_header, 0); curl_setopt ($ch, Curlopt_returntransfer, 1); curl_setopt ($ch, Curlopt_postfields, $data); $return = curl_exec ($ch); Curl_close ($ch); Print_r ($return); Accept the PHP page remote server: <?php if (isset ($_post[' name ')) { if (!empty ($_post[' name ')) { echo ' Hello, ', $_post[' name ']. '! ‘; } } ?>

Example 2

Use curl to simulate post request crawl ZIP code and address

Full code:

The code is as follows

Copy Code

#!/usr/local/php/bin/php <?php $runtime = new runtime (); $runtime->start (); $cookie _jar = Tempnam ('/tmp ', ' Cookie '); $filename = $argv [1]; $start _num= $argv [2]; $end _num = $argv [3]; for ($i = $start _num; $i < $end _num; $i + +) { $zip = sprintf (' 6s ', $i); $fields _post = Array ( ' Postcode ' = $zip, ' Querykind ' = 2, ' Reqcode ' = ' gotosearch ', ' Search_button.x ' =>37, ' Search_button.y ' =>12 ); $fields _string = http_build_query ($fields _post, ' & '); $ch = Curl_init (); curl_setopt ($ch, Curlopt_url, "url?reqcode=gotosearch&querykind=2&postcode=". $zip); curl_setopt ($ch, Curlopt_header, true); curl_setopt ($ch, Curlopt_returntransfer, true); curl_setopt ($ch, Curlopt_post, true); curl_setopt ($ch, Curlopt_connecttimeout, 120); curl_setopt ($ch, Curlopt_referer, $refer); curl_setopt ($ch, Curlopt_httpheader, $headers _login); curl_setopt ($ch, Curlopt_cookiefile, $cookie _jar); curl_setopt ($ch, Curlopt_cookiejar, $cookie _jar); curl_setopt ($ch, curlopt_useragent, $_server[' http_user_agent '); curl_setopt ($ch, Curlopt_post, 1); Send a regular POST request curl_setopt ($ch, Curlopt_postfields, $fields _string); $data = curl_exec ($ch); Preg_match_all ('/id= ' table1 ">[s]*?<tr>[s]*?<td class=" Maintext ">[ss]*?</td>[s]*?</tr >/', $data, $matches); if (! $handle = fopen ($filename, ' A + ')) { echo "Cannot open file $filename"; echo "n"; Exit } if (fwrite ($handle, $matches [0][1]) = = = = FALSE) { echo "Cannot write to file $filename"; echo "n"; Exit } echo "successfully wrote $somecontent to file $filename"; echo "n"; Fclose ($handle); Curl_close ($ch); } Class runtime { var $StartTime = 0; var $StopTime = 0; function Get_microtime () { List ($usec, $sec) =explode (", Microtime ()); return (float) $usec + (float) $sec); } function Start () { $this->starttime= $this->get_microtime (); } function Stop () { $this->stoptime= $this->get_microtime (); } function spent () { Return ($this->stoptime-$this->starttime); } } $runtime->stop (); $con = ' processed in '. $runtime->spent (). ' Seconds '; echo ' processed in '. $runtime->spent (). ' Seconds ';

Impersonate a POST request to submit data or upload a file.

.

The code is as follows

Copy Code

http://www.a.com/a.php Send a POST request function Execupload () { $file = '/doucment/readme.txt '; $ch = Curl_init (); $post _data = Array ( ' Loginfield ' = ' username ', ' Username ' = ' ybb ', ' Password ' = ' 123456 ', ' File ' = ' @d:usrwwwtranslatedocumentreadme.txt ' ); curl_setopt ($ch, Curlopt_header, false); When enabled, a regular post request is sent with the type: application/x-www-form-urlencoded, just as the form was submitted. curl_setopt ($ch, Curlopt_post, true); curl_setopt ($ch, curlopt_binarytransfer,true); curl_setopt ($ch, Curlopt_postfields, $post _data); curl_setopt ($ch, Curlopt_url, ' http://www.b.com/handleUpload.php '); $info = curl_exec ($ch); Curl_close ($ch); Print_r ($info); } 2.http://www.b.com/handleupload.php function Handleupload () { Print_r ($_post); Echo ' ===file upload info: '; Print_r ($_files); }
