PHP请求类型发布

Question

我在VB中遇到过这个函数，有人可以帮助我在PHP中转换它。 我如何将像API KEY这样的特定值解析为http标头？比如说API_KEY变量。

非常感谢...

Dim request = TryCast(System.Net.WebRequest.Create("https://domain.com/getticker"), 

System.Net.HttpWebRequest)
request.Method = "POST"
request.ContentType = "application/x-www-form-urlencoded"
request.Headers.Add("Content-Type", "application/x-www-form-urlencoded")
Using writer = New System.IO.StreamWriter(request.GetRequestStream())
  Dim byteArray As Byte() = System.Text.Encoding.UTF8.GetBytes("timestamp=1387132060")
  request.ContentLength = byteArray.Length
  writer.Write(byteArray)
  writer.Close()
End Using
Dim responseContent As String
Using response = TryCast(request.GetResponse(), System.Net.HttpWebResponse)
  Using reader = New System.IO.StreamReader(response.GetResponseStream())
    responseContent = reader.ReadToEnd()
  End Using
End Using
