Example of a curl batch implemented in PHP php curl download php curl.dll download php Curl simulator

Curl is an open source file Transfer tool that works with URL syntax in command line mode

This article implements a Curl batch instance in PHP.

The code is as follows:

1Header("Content-type:text/html;charset=utf8");23/*get all a labels for two pages first*/4//Initialize two simple handle handles5$ch 1=curl_init ();6$ch 2=curl_init ();7Curl_setopt_array ($ch 1,Array(8Curlopt_url = ' http://www.sina.com.cn ',9Curlopt_header = 0,TenCurlopt_returntransfer = 1, One)); ACurl_setopt_array ($ch 2,Array( -Curlopt_url = ' http://www.baidu.com/', -Curlopt_header = 0, theCurlopt_returntransfer = 1, -)); - -//Initializes a batch handle, and adds a simple handle to the processing handle +$MH=curl_multi_init (); -Curl_multi_add_handle ($MH,$ch 1); +Curl_multi_add_handle ($MH,$ch 2); A at//Initialize execution State -$state=NULL; - -//perform batch processing - Do{ -$MC= Curl_multi_exec ($MH,$state);  in} while($MC==curlm_call_multi_perform); - while($MC= = Curlm_ok &&$state) { to while(Curl_multi_exec ($MH,$state) ===curlm_call_multi_perform); +//after an experiment, it was found that curl_multi_select ($MH) always returns 1, meaning that the code will not execute -if(Curl_multi_select ($MH)! =-1) { the Do{ *$MC= Curl_multi_exec ($MH,$state); $} while($MC==curlm_call_multi_perform);Panax Notoginseng    }     -} the +//Get content A$text= Curl_multi_getcontent ($ch 1); the$text. = Curl_multi_getcontent ($ch 2); + -//Find all the A tags on the page and save to $matches $$matches=NULL; $Preg_match_all("/(.*?) <\/a>/",$text,$matches); - -//close each handle theCurl_multi_remove_handle ($MH,$ch 1); -Curl_multi_remove_handle ($MH,$ch 2);WuyiCurl_multi_close ($MH); the -/*continue to find the title tag in the found connection*/ Wu -$handle=Array();//arrays that store simple handle handles About$mhandle= Curl_multi_init ();//Batch handle $//Processing 100 pages -foreach(Array_slice($matches[1],0,100] as$href) { -$tmp _h=curl_init (); -Curl_setopt_array ($tmp _h,Array( ACurlopt_url =$href, +Curlopt_header = 0, theCurlopt_returntransfer = 1, -    )); $Curl_multi_add_handle ($mhandle,$tmp _h); the$handle[] =$tmp _h; the} the Do{ the$MRC= Curl_multi_exec ($mhandle,$active); -} while($MRC==curlm_call_multi_perform); in while($MRC= = Curlm_ok &&$active) { the while(Curl_multi_exec ($mhandle,$active) ==curlm_call_multi_perform); theif(Curl_multi_select ($mhandle)! =-1) { About Do{ the$MRC= Curl_multi_exec ($mhandle,$active); the} while($MRC==curlm_call_multi_perform); the    } +} - the//get the contents of these pagesBayi$mtext=NULL; theforeach($handle as$tmp _h) { the$mtext. = Curl_multi_getcontent ($tmp _h); -Curl_multi_remove_handle ($mhandle,$tmp _h); -} the$mmatches=Array(); thePreg_match_all("/<title>(.*?) <\/title>/",</title>$mtext,$mmatches); the the//Encoding Conversion -Mb_detect_order (' Gb2312,gbk,big5,gb18030,unicode, CP936 '); theforeach($mmatches[1] as$key=$val) { the$encoding= Mb_detect_encoding ($val); theif($encoding! = ' UTF-8 ' &&$encoding! = ' CP936 ' &&$encoding! = ' GB18030 ' &&$encoding!='') {94$mmatches[1] [$key] =Iconv($encoding, ' Utf-8//ignore ',$val); the    } the} the98//Print title Information AboutVar_dump($mmatches[1]); -101//close a batch handle102Curl_multi_close ($mhandle);

The above is introduced in PHP implementation of a Curl batch of examples, including the curl,php aspects of the content, I hope the PHP tutorial interested in a friend helpful.
