Note Submitter: bartosz dot zawadzki at gmail dot com ---- simple function that trims and removes repeating chairs from the middle of a string. i'm sure that it's not optimized, but it works for me <?php function mtrim($str,$chair=" ") // function that trims and removes repeating chairs from the middle of a string // { for ($i = 0; $i < strlen($chair); $i++) { $count = 1; $str = trim($str); while($count) { $str = str_replace($chair{$i}.$chair{$i}, $chair{$i}, $str, $count); } } return trim($str,$chair); } $string = "Anno\n\n\ndomini 2012"; echo mtrim($string," \n"); //double quote " /* output: Anno domini 2012 */ echo mtrim($string,' \n'); //single quote ' /* output: Ano domini 2012 */ ?> I know it can be done with preg_replace, but not everybody wish to work around escape sequences < http://www.php.net/manual/en/regexp.reference.escape.php > to remove doubled letter :) <?php // remove any whitespaces $str = trim(preg_replace("'\s+'", ' ', $str)); ?>
