用js进行url编码后用php反解以及用php实现js的escape功能函数总结

escape php smarty url function Function Can accomplish right Summarize use of coding conduct

smarty可以直接对url进行编码, 比如
但在smarttemplate里面就好像没有,由于链接是由js提交的,而不是表单提交,所以不能自动编码。
解决办法: 采用js对URL中的汉字进行escape编码。

这样点击链接后的效时:

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:

复制代码 代码如下:


function js_unescape($str)
{
$ret = '';
$len = strlen($str);
for ($i = 0; $i {
if ($str[$i] == '%' && $str[$i+1] == 'u')
{
$val = hexdec(substr($str, $i+2, 4));
if ($val else if($val >6)).chr(0x80|($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。
如下:

另外我找到个用PHP实现js的escape编码的函数:

复制代码 代码如下:


function phpescape($str)
{
$sublen=strlen($str);
$retrunString="";
for ($i=0;$i{
if(ord($str[$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;
}
