Hello Guys, This tutorial is all about How to Convert Number into Words in PHP. This tutorial is very easy and helpful as you will learn How to Convert Number into Words in PHP. So let’s get started:
First is to create a class name it “index.php” and put this code:
<!DOCTYPE>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Convert Number to Words</title>
</head>
<body>
<form method="post" action="">
<label>Enter Number
<input type="text" name="textfield" onchange="convert_number_to_words()" />
</label>
<input type="submit" value="Convert" />
</form>
<p>
Equivalent in words:
<?php
function convert_number_to_words($number) {
$hyphen = '-';
$conjunction = ' ';
$separator = ' ';
$negative = 'negative ';
$decimal = ' point ';
$dictionary = array(
0 => 'Zero',
1 => 'One',
2 => 'Two',
3 => 'Three',
4 => 'Four',
5 => 'Five',
6 => 'Six',
7 => 'Seven',
8 => 'Eight',
9 => 'Nine',
10 => 'Ten',
11 => 'Eleven',
12 => 'Twelve',
13 => 'Thirteen',
14 => 'Fourteen',
15 => 'Fifteen',
16 => 'Sixteen',
17 => 'Seventeen',
18 => 'Eighteen',
19 => 'Nineteen',
20 => 'Twenty',
30 => 'Thirty',
40 => 'Fourty',
50 => 'Fifty',
60 => 'Sixty',

);
if (!is_numeric($number)) {
return false;
}
if (($number >= 0 && (int) $number < 0) || (int) $number < 0 - PHP_INT_MAX) {
// overflow
trigger_error(
'convert_number_to_words only accepts numbers between -' . PHP_INT_MAX . ' and ' . PHP_INT_MAX,
E_USER_WARNING
);
return false;
}
if ($number < 0) {
return $negative . convert_number_to_words(abs($number));
}
$string = $fraction = null;
if (strpos($number, '.') !== false) {
list($number, $fraction) = explode('.', $number);
}
switch (true) {
case $number < 21:
$string = $dictionary[$number];
break;
case $number < 100:
$tens = ((int) ($number / 10)) * 10;
$units = $number % 10;
$string = $dictionary[$tens];
if ($units) {
$string .= $hyphen . $dictionary[$units];
}
break;
case $number < 1000:
$hundreds = $number / 100;
$remainder = $number % 100;
$string = $dictionary[$hundreds] . ' ' . $dictionary[100];
if ($remainder) {
$string .= $conjunction . convert_number_to_words($remainder);
}
break;
default:
$baseUnit = pow(1000, floor(log($number, 1000)));
$numBaseUnits = (int) ($number / $baseUnit);
$remainder = $number % $baseUnit;
$string = convert_number_to_words($numBaseUnits) . ' ' . $dictionary[$baseUnit];
if ($remainder) {
$string .= $remainder < 100 ? $conjunction : $separator;
$string .= convert_number_to_words($remainder);
}
break;
}
if (null !== $fraction && is_numeric($fraction)) {
$string .= $decimal;
$words = array();
foreach (str_split((string) $fraction) as $number) {
$words[] = $dictionary[$number];
}
$string .= implode(' ', $words);
}
return $string;
}
echo '<b>'.convert_number_to_words($_POST['textfield']).'</b>';
?>
</p>
</body>
