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

<span>php
</span><span>/*</span><span>*
 * 获取 http 请求数据
 </span><span>*/</span><span>//</span><span> 通过 $_SERVER 获取相关数据</span><span>echo</span> "PHP_SELF : " . <span>$_SERVER</span>['PHP_SELF'] . "<br>"<span>;
</span><span>echo</span> "GATEWAY_INTERFACE : " . <span>$_SERVER</span>['GATEWAY_INTERFACE'] . "<br>"<span>;
</span><span>echo</span> "SERVER_ADDR : " . <span>$_SERVER</span>['SERVER_ADDR'] . "<br>"<span>;
</span><span>echo</span> "SERVER_NAME : " . <span>$_SERVER</span>['SERVER_NAME'] . "<br>"<span>;
</span><span>echo</span> "SERVER_SOFTWARE : " . <span>$_SERVER</span>['SERVER_SOFTWARE'] . "<br>"<span>;

</span><span>echo</span> "HTTP_ACCEPT_ENCODING : " . <span>$_SERVER</span>['HTTP_ACCEPT_ENCODING'] . "<br>"<span>;
</span><span>echo</span> "HTTP_ACCEPT_LANGUAGE : " . <span>$_SERVER</span>['HTTP_ACCEPT_LANGUAGE'] . "<br>"<span>;
</span><span>echo</span> "HTTP_CONNECTION : " . <span>$_SERVER</span>['HTTP_CONNECTION'] . "<br>"<span>;
</span><span>echo</span> "HTTP_HOST : " . <span>$_SERVER</span>['HTTP_HOST'] . "<br>"<span>;

</span><span>echo</span> "REMOTE_ADDR : " . <span>$_SERVER</span>['REMOTE_ADDR'] . "<br>"<span>;
</span><span>echo</span> "REMOTE_HOST : " . <span>$_SERVER</span>['REMOTE_HOST'] . "<br>"<span>;
</span><span>echo</span> "REMOTE_PORT : " . <span>$_SERVER</span>['REMOTE_PORT'] . "<br>"<span>;
</span><span>echo</span> "REMOTE_USER : " . <span>$_SERVER</span>['REMOTE_USER'] . "<br>"<span>;
</span><span>echo</span> "REDIRECT_REMOTE_USER : " . <span>$_SERVER</span>['REDIRECT_REMOTE_USER'] . "<br>"<span>;
</span><span>echo</span> "SCRIPT_FILENAME : " . <span>$_SERVER</span>['SCRIPT_FILENAME'] . "<br>"<span>;
</span><span>echo</span> "SERVER_ADMIN : " . <span>$_SERVER</span>['SERVER_ADMIN'] . "<br>"<span>;
</span><span>echo</span> "SERVER_PORT : " . <span>$_SERVER</span>['SERVER_PORT'] . "<br>"<span>;

</span><span>echo</span> "ORIG_PATH_INFO : " . <span>$_SERVER</span>['ORIG_PATH_INFO'] . "<br>";

2、获取 get 数据 和 post 数据
http/http2.php

<span>php
</span><span>/*</span><span>*
 * 获取 get 数据 和 post 数据
 </span><span>*/</span><span>//</span><span> 获取 url 参数（get 数据）</span><span>$params</span> = getQueryParams(<span>$_SERVER</span>['QUERY_STRING'<span>]);
</span><span>echo</span> "param1: " . <span>$params</span>["param1"<span>];
</span><span>echo</span> "<br>"<span>;
</span><span>echo</span> "param2: " . <span>$params</span>["param2"<span>];
</span><span>echo</span> "<br>"<span>;

</span><span>function</span> getQueryParams(<span>$query</span><span>)
{
    </span><span>$queryParts</span> = <span>explode</span>('&', <span>$query</span><span>);
    </span><span>$params</span> = <span>array</span><span>();
    </span><span>foreach</span> (<span>$queryParts</span><span>as</span><span>$param</span><span>)
    {
        </span><span>$item</span> = <span>explode</span>('=', <span>$param</span><span>);
        </span><span>$params</span>[<span>$item</span>[0]] = <span>$item</span>[1<span>];
    }
    </span><span>return</span><span>$params</span><span>;
}



</span><span>//</span><span> 通过 $_POST 获取 post 数据
// 判断 $_POST["btnSubmit"] 是否存在，如果存在则表示有 post 过来的 form</span><span>if</span>  (<span>isset</span>(<span>$_POST</span>["btnSubmit"<span>]))
{
    </span><span>if</span> (<span>empty</span>(<span>$_POST</span>['txtUsername'<span>]))
    {
        </span><span>echo</span> "您没有输入用户名"<span>;
        </span><span>exit</span>(0<span>);
    }

    </span><span>echo</span> "您的用户名: " . <span>$_POST</span>['txtUsername'] . ""<span>;
}
</span>?>

姓名：

3、获取 get 数据 和 post 数据
encode/json.php

<span>php
</span><span>/*</span><span>*

}

</span><span>$jsonArray</span> = '<span>[
    {
        "name":{"firstName":"abc", "lastName":"xyz"},
        "number":1,
        "date1":"2015-12-30 10:00:48",
        "date2":1451440848
    },
    {

        "number":2,
        "date1":"2015-11-22 17:13:41",

</span><span>$myArray</span> = json_decode(<span>$jsonArray</span>, <span>true</span><span>);
</span><span>$myArrayCount</span> = <span>count</span>(<span>$myArray</span><span>);
</span><span>for</span> (<span>$i</span> = 0; <span>$i</span> $myArrayCount; <span>$i</span>++<span>)
{
    </span><span>$student</span> = <span>new</span><span> Student();
    </span><span>$student</span>-><span>number</span> = <span>$myArray</span>[<span>$i</span>]["number"<span>];
    </span><span>$student</span>->date1 = <span>$myArray</span>[<span>$i</span>]["date1"<span>];
    </span><span>$student</span>->date2 = <span>date</span>('Y-m-d H:i:s', <span>$myArray</span>[<span>$i</span>]["date2"<span>]);

    </span><span>$name</span> = <span>new</span><span> Name();
    </span><span>$jsonName</span> = <span>$myArray</span>[<span>$i</span>]["name"<span>];
    </span><span>$name</span>->firstName = <span>$jsonName</span>["firstName"<span>];
    </span><span>$name</span>->lastName = <span>$jsonName</span>["lastName"<span>];

    </span><span>$student</span>->name = <span>$name</span><span>;
    </span><span>$result</span>[] = <span>$student</span><span>;
}
</span><span>var_dump</span>(<span>$result</span><span>);

</span><span>//</span><span> 对象转 json 字符串</span><span>echo</span> json_encode(<span>$result</span><span>);
</span><span>echo</span> "<br>"<span>;

</span><span>echo</span> "<br>"<span>;


</span><span>//</span><span> 获取当前时间的时间戳（到 1970-1-1 的秒数）</span><span>echo</span><span>time</span><span>();
</span><span>echo</span> "<br>"<span>;

</span><span>//</span><span> 获取指定时间的时间戳（到 1970-1-1 的秒数）</span><span>echo</span><span>strtotime</span>("2015-12-30 16:00:10"<span>);
</span><span>echo</span> "<br>"<span>;

</span><span>//</span><span> 时间戳的格式化</span><span>echo</span><span>date</span>('Y-m-d H:i:s', <span>time</span><span>());
</span><span>echo</span> "<br>"<span>;

</span><span>//</span><span> 时间戳的格式化</span><span>echo</span><span>date</span>('Y-m-d H:i:s', 1460969676<span>);
</span><span>echo</span> "<br>";
