介绍
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 />";
