php模拟post提交请求，curl调用接口

/**
* 模拟post进行url请求
* @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;
$ch = curl_init();//初始化curl
curl_setopt($ch, CURLOPT_URL,$postUrl);//抓取指定网页
curl_setopt($ch, CURLOPT_HEADER, 0);//设置header
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);//要求结果为字符串且输出到屏幕上
curl_setopt($ch, CURLOPT_POST, 1);//post提交方式
curl_setopt($ch, CURLOPT_POSTFIELDS, $curlPost);
$data = curl_exec($ch);//运行curl
curl_close($ch);
return $data;
}
　　将拼接也封装了起来，这样调用的时候就更简洁了。

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);
}
