Getting rid of shouting

PHP
1

Hi,

Somebody posted this on my web site:

Nooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

How can I “disable” this type of shouting? i.e.,

This!!!

to This!

Would it be best to divide the string into an array (explode() with spaces) and process each word individually? Or… what? I want to make sure I do this efficiently, too.

Any suggestions are welcomed.

Thanks in advanced.

$string = "Nooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!";

$newstring = '';
$last = '';
$repititions = 0;
$max_repititions = 2;

for ($i = 0; $i < strlen($string); $i++) {

  if ($string{$i} == $last) {

    $repititions++;
    if ($repititions < $max_repititions)
      $newstring .= $string{$i};

  } else {

    $last = $string{$i};
    $repititions = 0;
    $newstring .= $string{$i};

  }

}

echo $string . "\
" . $newstring;

Output:

Nooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Noo!!

Don’t set max-repititions to 1 or you’ll change the word “cartoon” to “carton”.

Another possibility:

function RemoveExcessiveCharacters($String, $Limit = 3){
	$ReplaceString = str_repeat('\\1', $Limit);
	return preg_replace('/(.)' . $ReplaceString . '+/i', $ReplaceString, $String);
}
echo RemoveExcessiveCharacters('NNnNnNoooOooOooooOO!!!!!!!', 2);
//output: NNOO!!
