使用php模擬post傳值雖然在日常生活中用到的不是很多，但是在某些場(chǎng)合還是經(jīng)常用到的。下面VeVb武林網(wǎng)小編給大家整理了三種php模擬post傳值的方法，file_get_contents、curl和socket。
第一種：file_get_contents來(lái)模擬post
<phpfunction file_get_contents_post($url, $post){$options = array(‘http‘=> array(‘method‘=>‘POST‘,‘content‘=> http_build_query($post),),);$result = file_get_contents($url,false, stream_context_create($options));return $result;}$data = file_get_contents_post("http://www.a.com/post/post.php", array(‘name‘=>‘caiknife‘,‘email‘=>‘caiknife#gmail.com‘));var_dump($data); 第二種：curl模擬post
<phpfunction curl_post($url, $post){$options = array(CURLOPT_RETURNTRANSFER =>true,CURLOPT_HEADER =>false,CURLOPT_POST =>true,CURLOPT_POSTFIELDS => $post,);$ch = curl_init($url);curl_setopt_array($ch, $options);$result = curl_exec($ch);curl_close($ch);return $result;}$data = curl_post("http://www.a.com/post/post.php", array(‘name‘=>‘caiknife‘,‘email‘=>‘caiknife#gmail.com‘));var_dump($data); 第三種：socket來(lái)模擬post
<phpfunction socket_post($url, $post){$urls = parse_url($url);if(!isset($urls[‘port‘])){$urls[‘port‘]=80;}$fp = fsockopen($urls[‘host‘], $urls[‘port‘], $errno, $errstr);if(!$fp){echo "$errno, $errstr";exit();}$post = http_build_query($post);$length = strlen($post);$header =<<<HEADER<span class="Apple-tab-span" style="white-space:pre"></span>POST {$urls[‘path‘]} HTTP/1.1<span class="Apple-tab-span" style="white-space:pre"></span>Host:{$urls[‘host‘]}<span class="Apple-tab-span" style="white-space:pre"></span>Content-Type: application/x-www-form-urlencoded<span class="Apple-tab-span" style="white-space:pre"></span>Content-Length:{$length}<span class="Apple-tab-span" style="white-space:pre"></span>Connection: close<span class="Apple-tab-span" style="white-space:pre"></span>{$post}<span class="Apple-tab-span" style="white-space:pre"></span>HEADER;fwrite($fp, $header);$result =‘‘;while(!feof($fp)){$result .= fread($fp,512);}$result = explode("/r/n/r/n", $result,2);return $result[1];}$data = socket_post("http://www.a.com/post/post.php", array(‘name‘=>‘caiknife‘,‘email‘=>‘caiknife#gmail.com‘));var_dump($data); 上面這三種方法最后看到的內(nèi)容都是一樣的，都可以得到post的傳值；但是在是用socket的時(shí)候，發(fā)送header信息時(shí)必須要注意header的完整信息，比如content type和content length必須要有，connection: close和post數(shù)據(jù)之間要空一行，等等；而通過(guò)socket取得的內(nèi)容是包含了header信息的，要處理一下才能獲得真正的內(nèi)容。
下面給大家說(shuō)下php模擬post提交請(qǐng)求，調(diào)用接口
/*** 模擬post進(jìn)行url請(qǐng)求* @param string $url* @param string $param*/function request_post($url = '', $param = '') {if (empty($url) || empty($param)) {return false;}$postUrl = $url;$curlPost = $param;$ch = curl_init();//初始化curlcurl_setopt($ch, CURLOPT_URL,$postUrl);//抓取指定網(wǎng)頁(yè)curl_setopt($ch, CURLOPT_HEADER, 0);//設(shè)置headercurl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求結(jié)果為字符串且輸出到屏幕上curl_setopt($ch, CURLOPT_POST, 1);//post提交方式curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);$data = curl_exec($ch);//運(yùn)行curlcurl_close($ch);return $data;} 這是方法，
下面是具體的調(diào)用案例。
function testAction(){$url = 'http://mobile.jschina.com.cn/jschina/register.php';$post_data['appid'] = '10';$post_data['appkey'] = 'cmbohpffXVR03nIpkkQXaAA1Vf5nO4nQ';$post_data['member_name'] = 'zsjs123';$post_data['password'] = '123456';$post_data['email'] = 'zsjs123@126.com';$o = "";foreach ( $post_data as $k => $v ) { $o.= "$k=" . urlencode( $v ). "&" ;}$post_data = substr($o,0,-1);$res = $this->request_post($url, $post_data); print_r($res);} 這樣就提交請(qǐng)求，并且獲取請(qǐng)求結(jié)果了。一般返回的結(jié)果是json格式的。
這里的post是拼接出來(lái)的。
也可以改造成下面的方式。
/*** 模擬post進(jìn)行url請(qǐng)求* @param string $url* @param array $post_data*/function request_post($url = '', $post_data = array()) {if (empty($url) || empty($post_data)) {return false;}$o = "";foreach ( $post_data as $k => $v ) { $o.= "$k=" . urlencode( $v ). "&" ;}$post_data = substr($o,0,-1);$postUrl = $url;$curlPost = $post_data;$ch = curl_init();//初始化curlcurl_setopt($ch, CURLOPT_URL,$postUrl);//抓取指定網(wǎng)頁(yè)curl_setopt($ch, CURLOPT_HEADER, 0);//設(shè)置headercurl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求結(jié)果為字符串且輸出到屏幕上curl_setopt($ch, CURLOPT_POST, 1);//post提交方式curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);$data = curl_exec($ch);//運(yùn)行curlcurl_close($ch);return $data;} 將拼接也封裝了起來(lái)，這樣調(diào)用的時(shí)候就更簡(jiǎn)潔了。
function testAction(){$url = 'http://mobile.jschina.com.cn/jschina/register.php';$post_data['appid'] = '10';$post_data['appkey'] = 'cmbohpffXVR03nIpkkQXaAA1Vf5nO4nQ';$post_data['member_name'] = 'zsjs124';$post_data['password'] = '123456';$post_data['email'] = 'zsjs124@126.com';//$post_data = array();$res = $this->request_post($url, $post_data); print_r($res);}
