PHP如何对中文进行转义？

PHP如何对中文进行转义？

在PHP中可以通过使用“urlencode()”函数将中文进行转义，该函数的作用是对URL字符串进行编码，其语法为“urlencode($str )”，使用时将中文传入即可。

使用示例

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

<?php
function fullescape($in)
{
  $out = '';
  for ($i=0;$i<strlen($in);$i  )
  {
    $hex = dechex(ord($in[$i]));
    if ($hex=='')
       $out = $out.urlencode($in[$i]);
    else
       $out = $out .'%'.((strlen($hex)==1) ? ('0'.strtoupper($hex)):(strtoupper($hex)));
  }
  $out = str_replace(' ',' ',$out);
  $out = str_replace('_','_',$out);
  $out = str_replace('.','.',$out);
  $out = str_replace('-','-',$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("–", "-", $string);
      $string = str_replace("‘", "'", $string);
      $string = str_replace("’", "'", $string);
      $string = str_replace("‚", "'", $string);
      $string = str_replace("“", """, $string);
      $string = str_replace("”", """, $string);
      $string = str_replace("„", """, $string);
      $string = str_replace("‹", "«", $string);
      $string = str_replace("›", "»", $string);

      return $string;
   }
?>
