php curl用法
在php使用curl时必须先在php.ini中开启extension=php_curl.dll前面的;去了才行,curl是php中一款内置的浏览器,它可以模仿用户浏览信息进行网站浏览,等下面来看一实例,代码如下:
function postpage( $url ) { $response = "" ; $rd =rand(1,4); $proxy = 'http://221.214.27.253:808' ; if ( $rd ==2) $proxy = 'http://222.77.14.56:8088' ; if ( $rd ==3) $proxy = 'http://202.98.123.126:8080' ; if ( $rd ==4) $proxy = 'http://60.14.97.38:8080' ; if ( $url != "" ) { $ch = curl_init( $url ); curl_setopt( $ch , curlopt_header, 0); curl_setopt( $ch , curlopt_returntransfer, true); curl_setopt( $ch , curlopt_proxy, $proxy ); $response = curl_exec( $ch ); if (curl_errno( $ch )) $response = "" ; curl_close( $ch ); } return $response ; }curl包括部份函数,如下所示:
curl_close — close a curl session curl_copy_handle — copy a curl handle along with all of its preferences curl_errno — return the last error number curl_error — return a string containing the last error for the current session curl_exec — perform a curl session curl_getinfo — get information regarding a specific transfer curl_init — initialize a curl session curl_multi_add_handle — add a normal curl handle to a curl multi handle curl_multi_close — close a set of curl handles curl_multi_exec — run the sub-connections of the current curl handle curl_multi_getcontent — return the content of a curl handle if curlopt_returntransfer is set curl_multi_info_read — get information about the current transfers curl_multi_init — returns a new curl multi handle curl_multi_remove_handle — remove a multi handle from a set of curl handles curl_multi_select — wait for activity on any curl_multi connection curl_setopt_array — set multiple options for a curl transfer curl_setopt — set an option for a curl transfer curl_version — gets curl version information查看更多关于php curl用法 - php函数的详细内容...
