PHP实现高亮度代码

  <?
  function HeighPHPcode($Heightstring){
  do{
  $z=0;
  if(preg_match(‘/<phpcode>(.*)</phpcode>/sU’,$Heightstring,$reg)) {
  $z=1;
  $code=”;
  ob_start();
  highlight_string($reg[1]);
  $code = ob_get_contents();
  ob_end_clean();
  $reg[1] = addslashes($reg[1]);
  $Heightstring=preg_replace(“/<phpcode>(.*)</phpcode>/sU”,”$code”,$Heightstring,1);
  }
  }while($z);
  return $Heightstring;
  }
