一分钟解读js与PHP 设置cookie的相互读取（附代码）

PHP与JavaScript下Cookie的交互使用下面的例子列出几种情形交互场景，列出JS和php交互的方法。总结下，以免日后再为cookie问题困扰。setcookie.php<?php    setcookie('php_cn_ck','php_中文_cookie');setcookie('php_en_ck','php_english_cookie');?><script src="cookie.js"></script><script>    Cookies.set('js_cn_ck','js_中文_cookie',5000); Cookies.set('js_en_ck','js_english_cookie');</script><meta http-equiv="Content-Type" content="text/html; charset=utf8">PHP cookie已经设置<br>php_cn_ck=php_中文_cookie<br>php_en_ck=php_english_cookie<br><br>JS cookie已经设置<br>js_cn_ck=js_中文_cookie<br>js_en_ck=js_english_cookie<br><br><a href="https://zhishitu.com/ke" http-equiv="Content-Type" content="text/html; charset=utf8">一 读取php传送的中英文cookie<br><br><p>1 php读取php设置php cookie<br><br><?phpinclude('function.php'); $php_cn_ck=$_COOKIE['php_cn_ck'];  $un_php_cn_ck=unescape($php_cn_ck);    echo "解码前的中文cookie:php_cn_ck=$php_cn_ck<br><br>";    echo "解码后的中文cookie:un_php_cn_ck=$un_php_cn_ck<br><br>";10        $php_en_ck=$_COOKIE['php_en_ck'];    11       echo "英文cookie无需解码:php_en_ck=$php_en_ck<br><br>";    12    ?>    13    <p>2 js读取php设置cookie<br><br>    14    <script src="cookie.js"></script>    15    <script>    16        php_cn_ck=Cookies.get('php_cn_ck');    17        un_php_cn_ck = decodeURIComponent (escape(php_cn_ck));    18       document.write("解码前的中文cookie :php_cn_ck="+php_cn_ck+"<Br><br>");    19        document.write("解码后的中文cookie :un_php_cn_ck="+un_php_cn_ck+"<Br><br>");    20        php_en_ck=Cookies.get('php_en_ck');    21      document.write("英文cookie无需解码 :php_en_ck="+php_en_ck+"<Br><br>");    22    </script>    23    -----------------------------------------------<br>    24    二 读取JS传送的中英文cookie<br><br>    25    <p>1 php读取JS设置js cookie<br><br>    26    <?php    27        $js_cn_ck=$_COOKIE['js_cn_ck'];    28      $un_js_cn_ck=unescape($js_cn_ck);    29      echo "解码前的中文cookie:js_cn_ck=$js_cn_ck<br><br>";    30        echo "解码后的中文cookie:un_js_cn_ck=$un_js_cn_ck<br><br>";    31        $js_en_ck=$_COOKIE['js_en_ck'];    32        echo "英文cookie无需解码:js_en_ck=$js_en_ck<br><br>";    33    ?>    34    </p>    35    <p>2 js读取js设置的cookie<br><br>    36    <script>    37        js_cn_ck=Cookies.get('js_cn_ck');    38        document.write("解码前的中文cookie :js_cn_ck="+js_cn_ck+"<Br><br>");    39        //un_js_cn_ck = decodeURIComponent (escape(js_cn_ck)); 调用这两句会出现js解析中断    40        //document.write("解码后的中文cookie :un_js_cn_ck="+un_js_cn_ck+"<Br><br>");    41        js_en_ck=Cookies.get('js_en_ck');    42        document.write("英文cookie无需解码 :js_en_ck="+js_en_ck+"<Br><br>");    43    </script>    44    </p>    总结:php用自身函数读取php 的cookie，没有任何障碍，无需解码处理。js采用cookie.js方法读取js 的cookie，没有任何障碍，无需解码处理。js读取php的中文cookie，需要做 "decodeURIComponent (escape(php_cn_ck)) "函数处理php读取js的中文cookie 需要做 "unescape()" 函数处理cookie.jsview sourceprint    ?01        var Cookies = {};    02        /**    03        * 设置Cookies    04        */    05        Cookies.set = function(name, value){    06            var argv = arguments;    07            var argc = arguments.length;    08            var expires = (argc > 2) ? argv[2] : null;    09            if(expires != null){    10                var exp　　 = new Date();    11                exp.setTime(exp.getTime() + 8*3600 + expires);    12            }    13            alert(exp.toGMTString());    14            var path = (argc > 3) ? argv[3] : '/';    15            var domain = (argc > 4) ? argv[4] : null;    16            var secure = (argc > 5) ? argv[5] : false;    17            document.cookie = name + "=" + escape (value) +    18            ((expires == null) ?
