Hex htmlentities

I'm checking a couple of things in phpDig 1.6.4.

In robot_functions.php, the function phpdigCleanHtml has a line:

Quote:

$text = ereg_replace('&#([0-9]+);',chr('\1').' ',$text);

I guess that this line recognises entities such as ' & # 233; ' as being lowercase e with acute accent.

I see no code to recognise equivalent entities such as ' & # x e9; '. If these hex entities aren't currently recognised, could the code be added to recognise them?

Hi. In robot_functions find:

PHP Code:


		
			
$text = ereg_replace('&#([0-9]+);',chr('\\1').' ',$text);

and replace with:

PHP Code:


		
			
while (eregi('&#([0-9]{3});',$text,$reg)) {

    $text = str_replace($reg[0],chr($reg[1]),$text);

}

while (eregi('&#x([a-f0-9]{2});',$text,$reg)) {

    $text = str_replace($reg[0],chr(base_convert($reg[1],16,10)),$text);

}
