Sample code for php curl to simulate post requests and submit multi-dimensional arrays, curl sample code

The following code introduces to you the sample code for php curl to simulate post requests. The specific code is as follows:

<&#63;php
$uri = "http://www.cnblogs.com/test.php";//这里换成自己的服务器的地址
// 参数数组
$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);

2, Remote server:

<&#63;php
if(isset($_POST['name'])){
 if(!empty($_POST['name'])){
 echo '您好，',$_POST['name'].'！';
 }
}

The following will introduce curl to simulate post submission of multi-dimensional arrays in PHP.

Today, we need to use curl to simulate post submission parameters and request an interface provided by colleagues; however, among the parameters passed, the value of one parameter is an array. If submitted with ordinary curl post code, an error will be reported

PHP Notice: Array to string conversion in /test/functions.php on line 30
Notice: Array to string conversion in /test/functions.php on line 30

The code is as follows:

<&#63;php
        $param = array(
                'uid' => 123, 
                'uids' => array(12,455), 
                'msgType' => 'WITH',  
                'nick' => 'aaa',   
               );
        $url = "http://cx.com/t.php";
        //通过curl的post方式发送接口请求
        SendDataByCurl($url,$param);
       //通过curl模拟post的请求；
function SendDataByCurl($url,$data=array()){
  //对空格进行转义
  $url = str_replace(' ','+',$url);
  $ch = curl_init();
  //设置选项，包括URL
  curl_setopt($ch, CURLOPT_URL, "$url");
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch,CURLOPT_TIMEOUT,3); //定义超时3秒钟 
   // POST数据
  curl_setopt($ch, CURLOPT_POST, 1);
  // 把post的变量加上
  curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
  //执行并获取url地址的内容
  $output = curl_exec($ch);
  //释放curl句柄
  curl_close($ch);
  return $output;
}

After modifying the above code, you can complete the function of submitting the array without reporting a php notice. The code is as follows:

//通过curl模拟post的请求；
function SendDataByCurl($url,$data=array()){
  //对空格进行转义
  $url = str_replace(' ','+',$url);
  $ch = curl_init();
  //设置选项，包括URL
  curl_setopt($ch, CURLOPT_URL, "$url");
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch,CURLOPT_TIMEOUT,3); //定义超时3秒钟 
   // POST数据
  curl_setopt($ch, CURLOPT_POST, 1);
  // 把post的变量加上
  curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));  //所需传的数组用http_bulid_query()函数处理一下，就ok了
  //执行并获取url地址的内容
  $output = curl_exec($ch);
  $errorCode = curl_errno($ch);
  //释放curl句柄
  curl_close($ch);
  if(0 !== $errorCode) {
    return false;
  }
  return $output;
}
