note 39078 added to function.is-numeric

Here is a simple function that I found usefull for filtering user input into numbers. Basically, it attempts to fix fat fingering. For example: $userString = "$654.4r5"; function numpass_filter($userString){ $money = explode(".", $userString); //now $money[0] = "$645" and $money[1] = "4r5" //next remove all characters save 0 though 9 //in both elements of the array $dollars = eregi_replace("[^0-9]", null, $money[0]); $cents = eregi_replace("[^0-9]", null, $money[1]); //if there was a decimal in the original string, put it back if((string)$cents!=null){ $cents = "." . $cents; } $result = $dollars . $cents; return($result); } The output in this case would be '654.45'. Please note that this function will work properly unless the user fat fingers an extra decimal in the wrong place. ---- Manual Page -- http://www.php.net/manual/en/function.is-numeric.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+39078 Delete -- http://master.php.net/manage/user-notes.php?action=delete+39078&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+39078&report=yes Search -- http://master.php.net/manage/user-notes.php
