note 58314 added to function.ord

I wrote the following function to clean illegal characters from input strings. (Background: I have a php-based news website. People were writing articles in MS Word, then copy-and-pasting the text into the website. Word uses non-standard characters for opening and closing quotes and double-quotes, and for "..." - and this was resulting in articles on the website that failed XHTML validation) <?php function clean_string_input($input) { $interim = strip_tags($input); if(get_magic_quotes_gpc()) { $interim=stripslashes($interim); } // now check for pure ASCII input // special characters that might appear here: // 96: opening single quote (not strictly illegal, but substitute anyway) // 145: opening single quote // 146: closing single quote // 147: opening double quote // 148: closing double quote // 133: ellipsis (...) // 163: pound sign (this is safe, so no substitution required) // these can be substituted for safe equivalents $result = ''; for ($i=0; $i<strlen($interim); $i++) { $char = $interim{$i}; $asciivalue = ord($char); if ($asciivalue == 96) { $result .= '\\''; } else if (($asciivalue > 31 && $asciivalue < 127) || ($asciivalue == 163) || // pound sign ($asciivalue == 10) || // lf ($asciivalue == 13)) // cr { // it's already safe ASCII $result .= $char; } else if ($asciivalue == 145) // opening single quote { $result .= '\\''; } else if ($asciivalue == 146) // closing single quote { $result .= '\\''; } else if ($asciivalue == 147) // opening double quote { $result .= '"'; } else if ($asciivalue == 148) // closing double quote { $result .= '"'; } else if ($asciivalue == 133) // ellipsis { $result .= '...'; } } return $result; } ?> ---- Manual Page -- http://www.php.net/manual/en/function.ord.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+58314 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+58314&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+58314&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+58314&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+58314&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+58314&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+58314&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+58314&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+58314&report=yes Search -- http://master.php.net/manage/user-notes.php
