Here’s something I’m working on. Go ahead and critique it to your hearts desire. Any suggestions will be appreciated. (Yes I know it would be faster to just hard code the drop down list stuff instead of using a for loop on a multidimensional array… But I was being lazy =P)

// Validation Class
// Validates and cleans user based input
// Ver 0.1
// Kenneth Ellis Mccall – August 8th 2007
//
// Functions:
// email():
// Validate an email address
//
// variables:
// $email: Email address.
// $level: Values 1, 2, 3 and 4.
// 1 = Simple regex checking. Default. (Fastest) — Need to add valid TLD’s (.com, .net)
// 2 = Checks to make sure the domain is valid and has an MX record. (Fast)
// 3 = Connects to the mail server and checks to if it really exsists. Doesn’t always work. (Slow)
// 4 = Check to see if the user does exist on the server. Doesn’t always work. (Slowest) — Not completed
//
// phone():
// Validate and clean phone number
//
// variables:
// $phone: Phone number.
// $level: Values 1 and 2.
// 1 = Simple check of US phone number – allow for ()’s, -‘s, spaces and .’s. — Regex isn’t 100% complete to what I want.
// 2 = Format to a simple 10 digit number.
//
// list_pre():
// Returns a form list element of name prefixes and also uses the SELECTED command to show the previous choice
//
// variables:
// $pre: Selection
//
// list_suf():
// Returns a form list element of name suffixes and also uses the SELECTED command to show the previous choice
//
// variables:
// $suf: Selection
//
// list_states():
// Returns a form list element of states and also uses the SELECTED command to show the previous choice
//
// variables:
// $state: Selection
//
// check_pre():
// check to make sure prefixes form element doesn’t have any injection.
//
// variables:
// $pre: prefix selection
//
// check_suf():
// check to make sure suffixes form element doesn’t have any injection.
//
// variables:
// $suf: suffix selection
//
// check_state
// check to make sure states form element doesn’t have any injection.
//
// variables:
// $state: state
//
// slash():
// Escapes strings – auto detects magic quotes and which escaping mechanism to use.
// Use stripslashes() to unescape.
//
// variables:
// $str: string
//
// fixword():
// Converts MS Word quotes and dashes to HTML
//
// variables:
// $str: string
