PHP Transform string to UTF-8 encoding
Here are some nice pieces of code that allow you to make all your data (i.e. when it comes from datafeeds) consistant in UTF-8
function utf8_transform($content)
{
if(!mb_check_encoding($content, 'UTF-8')
OR !($content === mb_convert_encoding(mb_convert_encoding($content, 'UTF-32', 'UTF-8' ), 'UTF-8', 'UTF-32'))) {
$content = mb_convert_encoding($content, 'UTF-8');
if (mb_check_encoding($content, 'UTF-8')) {
// log('Converted to UTF-8');
} else {
// log('Could not converted to UTF-8');
}
}
return $content;
}
Another function is this one, that transforms a string so it fits the formats of MySQL better
function utf8_transform_mysql($string)
{
if(empty($string))
{
return $string;
}
$string = preg_match_all("#[\x09\x0A\x0D\x20-\x7E]|[\xC2-\xDF][\x80-\xBF]|\xE0[\xA0-\xBF][\x80-\xBF]|[\xE1-\xEC\xEE\xEF][\x80-\xBF]{2}|\xED[\x80-\x9F][\x80-\xBF]#x", $string, $matches );
return implode("",$matches[0]);
}

Validate creditcard number
This piece of code will check if a creditcard number could possibly be valid, determined on the number ranges given. It will NOT actually validate the number with the creditcard company but it could function as a pre-check.
function validate_creditcard($number)
{
$false = false;
$card_type = "";
$card_regexes = array(
"/^4\d{12}(\d\d\d){0,1}$/" => "visa",
"/^5[12345]\d{14}$/" => "mastercard",
"/^3[47]\d{13}$/" => "amex",
"/^6011\d{12}$/" => "discover",
"/^30[012345]\d{11}$/" => "diners",
"/^3[68]\d{12}$/" => "diners",
);
foreach ($card_regexes as $regex => $type) {
if (preg_match($regex, $number)) {
$card_type = $type;
break;
}
}
if (!$card_type) {
return $false;
}
$revcode = strrev($number);
$checksum = 0;
for ($i = 0; $i < strlen($revcode); $i++) {
$current_num = intval($revcode[$i]);
if($i & 1) {
$current_num *= 2;
}
$checksum += $current_num % 10; if
($current_num > 9) {
$checksum += 1;
}
}
if ($checksum % 10 == 0) {
return $card_type;
} else {
return $false;
}
}

Validate dutch bank account
This is a piece of code used to validate bank account numbers in the Netherlands, and maybe also in other countries. This is also called the ’11-proef’.
function validate_bank($number)
{
$start=0;
$end=9;
for($i = 0; $i < strlen($number); $i++)
{
$num=substr($number,$i,1);
if ( is_numeric( $num ))
{
$start+=$num * $end;
$end--;
}
}
$giro=($end> 1) && ($end< 7);
$mod=$start% 11;
return($giro || !($end || $mod));
}
