Re: Re: [PHP] CR and LF Filtering

This function takes as argument a single string, the sting most likly being a line from a file. It returns the string formatted as though it was printed on the console or through a carriage (dot matrix) printer. ------------------------------------------------------ // removes all ascii charactor 13 (carriage returns) // compresses the content to emulate the output a carriage printer would give function compressCR ($str){ $pos = strpos($str, 13); // find position of first CR $i = 0; while (!($pos === false)) { // while a CR exists if ($pos == 0){ // CR = first char of string $str = substr($str, ($pos + 1)); // save all after CR } else { $newStr[$i] = substr($str, 0, $pos); // save all before CR $str = substr($str, ($pos + 1)); // save from char ($pos+4) to end } $i++; $pos = strpos($str, 13); // find postition of next CR } $newStr[$i] = $str; $j = 1; $str = chop($newStr[0]); // remove trailling spaces while ($newStr[$j]){ // while array element exists $str .= chop(substr($newStr[$j], strlen($str))); // add two string together // first removing the number of charactors // in the first string from the beginning // of the second string $j++; } return $str; } ------------------------------------------------------ Hope you find this useful. I would like to hear any comments you have on it.
