速战速决 之 PHP


  • 获取 http 请求数据
  • 获取 get 数据 和 post 数据
  • json 字符串与对象之间的相互转换


示例

1、获取 http 请求数据

http/http1.php


<?php /**  * 获取 http 请求数据  */  // 通过 $_SERVER 获取相关数据 echo "PHP_SELF : " . $_SERVER['PHP_SELF'] . "<br />"; echo "GATEWAY_INTERFACE : " . $_SERVER['GATEWAY_INTERFACE'] . "<br />"; echo "SERVER_ADDR : " . $_SERVER['SERVER_ADDR'] . "<br />"; echo "SERVER_NAME : " . $_SERVER['SERVER_NAME'] . "<br />"; echo "SERVER_SOFTWARE : " . $_SERVER['SERVER_SOFTWARE'] . "<br />"; echo "SERVER_PROTOCOL : " . $_SERVER['SERVER_PROTOCOL'] . "<br />"; echo "REQUEST_METHOD : " . $_SERVER['REQUEST_METHOD'] . "<br />"; echo "REQUEST_TIME : " . $_SERVER['REQUEST_TIME'] . "<br />"; echo "REQUEST_TIME_FLOAT : " . $_SERVER['REQUEST_TIME_FLOAT'] . "<br />"; echo "QUERY_STRING : " . htmlspecialchars($_SERVER['QUERY_STRING']) . "<br />"; echo "DOCUMENT_ROOT : " . $_SERVER['DOCUMENT_ROOT'] . "<br />"; echo "HTTP_ACCEPT : " . $_SERVER['HTTP_ACCEPT'] . "<br />"; echo "HTTP_ACCEPT_CHARSET : " . $_SERVER['HTTP_ACCEPT_CHARSET'] . "<br />"; echo "HTTP_ACCEPT_ENCODING : " . $_SERVER['HTTP_ACCEPT_ENCODING'] . "<br />"; echo "HTTP_ACCEPT_LANGUAGE : " . $_SERVER['HTTP_ACCEPT_LANGUAGE'] . "<br />"; echo "HTTP_CONNECTION : " . $_SERVER['HTTP_CONNECTION'] . "<br />"; echo "HTTP_HOST : " . $_SERVER['HTTP_HOST'] . "<br />"; echo "HTTP_REFERER : " . $_SERVER['HTTP_REFERER'] . "<br />"; echo "HTTP_USER_AGENT : " . $_SERVER['HTTP_USER_AGENT'] . "<br />"; echo "HTTPS : " . $_SERVER['HTTPS'] . "<br />"; echo "REMOTE_ADDR : " . $_SERVER['REMOTE_ADDR'] . "<br />"; echo "REMOTE_HOST : " . $_SERVER['REMOTE_HOST'] . "<br />"; echo "REMOTE_PORT : " . $_SERVER['REMOTE_PORT'] . "<br />"; echo "REMOTE_USER : " . $_SERVER['REMOTE_USER'] . "<br />"; echo "REDIRECT_REMOTE_USER : " . $_SERVER['REDIRECT_REMOTE_USER'] . "<br />"; echo "SCRIPT_FILENAME : " . $_SERVER['SCRIPT_FILENAME'] . "<br />"; echo "SERVER_ADMIN : " . $_SERVER['SERVER_ADMIN'] . "<br />"; echo "SERVER_PORT : " . $_SERVER['SERVER_PORT'] . "<br />"; echo "SERVER_SIGNATURE : " . $_SERVER['SERVER_SIGNATURE'] . "<br />"; echo "PATH_TRANSLATED : " . $_SERVER['PATH_TRANSLATED'] . "<br />"; echo "SCRIPT_NAME : " . $_SERVER['SCRIPT_NAME'] . "<br />"; echo "REQUEST_URI : " . htmlspecialchars($_SERVER['REQUEST_URI']) . "<br />"; echo "PHP_AUTH_DIGEST : " . $_SERVER['PHP_AUTH_DIGEST'] . "<br />"; echo "PHP_AUTH_USER : " . $_SERVER['PHP_AUTH_USER'] . "<br />"; echo "PHP_AUTH_PW : " . $_SERVER['PHP_AUTH_PW'] . "<br />"; echo "AUTH_TYPE : " . $_SERVER['AUTH_TYPE'] . "<br />"; echo "PATH_INFO : " . $_SERVER['PATH_INFO'] . "<br />"; echo "ORIG_PATH_INFO : " . $_SERVER['ORIG_PATH_INFO'] . "<br />";


2、获取 get 数据 和 post 数据

http/http2.php


<?php /**  * 获取 get 数据 和 post 数据  */  // 获取 url 参数（get 数据） $params = getQueryParams($_SERVER['QUERY_STRING']); echo "param1: " . $params["param1"]; echo "<br />"; echo "param2: " . $params["param2"]; echo "<br />";  function getQueryParams($query) {     $queryParts = explode('&', $query);     $params = array();     foreach ($queryParts as $param)     {         $item = explode('=', $param);         $params[$item[0]] = $item[1];     }     return $params; }    // 通过 $_POST 获取 post 数据 // 判断 $_POST["btnSubmit"] 是否存在，如果存在则表示有 post 过来的 form if  (isset($_POST["btnSubmit"])) {     if (empty($_POST['txtUsername']))     {         echo "您没有输入用户名";         exit(0);     }      echo "您的用户名: " . $_POST['txtUsername'] . ""; } ?>  <form action="" method="post">     <div>姓名：</div>     <div><input type="text" id="txtUsername" name="txtUsername" value="wanglei" /></div>      <div><input type="submit" name="btnSubmit" value="提交"/></div> </form>


3、获取 get 数据 和 post 数据

encode/json.php


<?php /**  * Created by PhpStorm.  * User: wanglei  * Date: 2015/12/30  * Time: 9:45  */  class Name {     public $firstName;     public $lastName; }  class Student {     public $name;      public $number;     public $date1;     public $date2; }  $jsonArray = ' [     {         "name":{"firstName":"abc", "lastName":"xyz"},         "number":1,         "date1":"2015-12-30 10:00:48",         "date2":1451440848     },     {         "name":{"firstName":"lmn", "lastName":"rst"},         "number":2,         "date1":"2015-11-22 17:13:41",         "date2":1448183621     } ]';  // 设置当前时区为东八时区（北京时区） date_default_timezone_set("Etc/GMT-8");  // json 字符串转对象 $result = array(); $myArray = json_decode($jsonArray, true); $myArrayCount = count($myArray); for ($i = 0; $i < $myArrayCount; $i++) {     $student = new Student();     $student->number = $myArray[$i]["number"];     $student->date1 = $myArray[$i]["date1"];     $student->date2 = date('Y-m-d H:i:s', $myArray[$i]["date2"]);      $name = new Name();     $jsonName = $myArray[$i]["name"];     $name->firstName = $jsonName["firstName"];     $name->lastName = $jsonName["lastName"];      $student->name = $name;     $result[] = $student; } var_dump($result);  // 对象转 json 字符串 echo json_encode($result); echo "<br />";  echo "<br />";   // 获取当前时间的时间戳（到 1970-1-1 的秒数） echo time(); echo "<br />";  // 获取指定时间的时间戳（到 1970-1-1 的秒数） echo strtotime("2015-12-30 16:00:10"); echo "<br />";  // 时间戳的格式化 echo date('Y-m-d H:i:s', time()); echo "<br />";  // 时间戳的格式化 echo date('Y-m-d H:i:s', 1460969676); echo "<br />";
