这篇文章主要介绍了关于js和php对url编码的处理方法,需要的朋友可以参考下

解决办法：采用js对URL中的汉字进行escape编码。代码如下: 这样点击链接后的效时：引用：http://127.0.0.1/shop/product_list.php?p_sort=PHP%u5F00%u53D1%u8D44%u6E90%u7F51 生成了这样的效果, 很明显用PHP的urldecode()或者base64_decode()是无法反解的。解决方法, 用PHP写一个反解函数：代码如下: function js_unescape($str){ $ret = ''; $len = strlen($str); for ($i = 0; $i >6)).chr(0x80|($val&0x3f)); else $ret .= chr(0xe0|($val>>12)).chr(0x80|(($val>>6)&0x3f)).chr(0x80|($val&0x3f)); $i += 5; } else if ($str[$i] == '%'){ $ret .= urldecode(substr($str, $i, 3)); $i += 2; } else $ret .= $str[$i]; } return $ret; } 注意JS编码会自动转换成为UTF-8, 所以必须进行编码转换才能得到正确的结果，否则会中文乱码。代码如下: print iconv('utf-8', 'gb2312', js_unescape($_REQUEST['p_sort'])); 到此我们就成功地反解了js的escape编码了。另外我找到个用PHP实现js的escape编码的函数：代码如下: function phpescape($str){ $sublen=strlen($str); $retrunString=""; for ($i=0;$i=127){ $tmpString=bin2hex(iconv("gb2312","ucs-2",substr($str,$i,2))); //$tmpString=substr($tmpString,2,2).substr($tmpString,0,2);window下可能要打开此项 $retrunString.="%u".$tmpString; $i++; } else { $retrunString.="%".dechex(ord($str[$i])); }} return $retrunString; }
