How to escape Chinese in PHP?

#How does PHP escape Chinese?

In PHP, Chinese can be escaped by using the "urlencode()" function. The function of this function is to encode the URL string. Its syntax is "urlencode($str)", Just pass in Chinese when using it.

Usage examples

<?php
echo &#39;<a href="mycgi?foo=&#39;, urlencode($userinput), &#39;">&#39;;
?>

<?php
function fullescape($in)
{
  $out = &#39;&#39;;
  for ($i=0;$i<strlen($in);$i++)
  {
    $hex = dechex(ord($in[$i]));
    if ($hex==&#39;&#39;)
       $out = $out.urlencode($in[$i]);
    else
       $out = $out .&#39;%&#39;.((strlen($hex)==1) ? (&#39;0&#39;.strtoupper($hex)):(strtoupper($hex)));
  }
  $out = str_replace(&#39;+&#39;,&#39;%20&#39;,$out);
  $out = str_replace(&#39;_&#39;,&#39;%5F&#39;,$out);
  $out = str_replace(&#39;.&#39;,&#39;%2E&#39;,$out);
  $out = str_replace(&#39;-&#39;,&#39;%2D&#39;,$out);
  return $out;
}
?>

<?php
   function flash_encode ($input)
   {
      return rawurlencode(utf8_encode($input));
   }
?>

... could do the problem. Unfortunately flash still have problems with read some quotations, but with this one:

<?php
   function flash_encode($string)
   {
      $string = rawurlencode(utf8_encode($string));

      $string = str_replace("%C2%96", "-", $string);
      $string = str_replace("%C2%91", "%27", $string);
      $string = str_replace("%C2%92", "%27", $string);
      $string = str_replace("%C2%82", "%27", $string);
      $string = str_replace("%C2%93", "%22", $string);
      $string = str_replace("%C2%94", "%22", $string);
      $string = str_replace("%C2%84", "%22", $string);
      $string = str_replace("%C2%8B", "%C2%AB", $string);
      $string = str_replace("%C2%9B", "%C2%BB", $string);

      return $string;
   }
?>
