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=getcookie.php>读取cookie</a><br> getcookie.php <meta 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> <?php include('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.js view source print ? 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) ?
