Use the NumberFormatter class that are in php ;)
$f = new NumberFormatter("en", NumberFormatter::SPELLOUT);
echo $f->format(1432);
That would output "one thousand four hundred thirty-two"

You can do this in many ways I am mentioning here two ways by using The NumberFormatter class as mentioned in Martindilling answer (if you have php version 5.3.0 or higher and also PECL extension 1.0.0 or higher) or by using the following custom function.
function convertNumberToWord($num = false)
{
$num = str_replace(array(',', ' '), '' , trim($num));
if(! $num) {
return false;
}
$num = (int) $num;
$words = array();
$list1 = array('', 'one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten', 'eleven',
'twelve', 'thirteen', 'fourteen', 'fifteen', 'sixteen', 'seventeen', 'eighteen', 'nineteen'
);
$list2 = array('', 'ten', 'twenty', 'thirty', 'forty', 'fifty', 'sixty', 'seventy', 'eighty', 'ninety', 'hundred');
$list3 = array('', 'thousand', 'million', 'billion', 'trillion', 'quadrillion', 'quintillion', 'sextillion', 'septillion',
'octillion', 'nonillion', 'decillion', 'undecillion', 'duodecillion', 'tredecillion', 'quattuordecillion',
'quindecillion', 'sexdecillion', 'septendecillion', 'octodecillion', 'novemdecillion', 'vigintillion'
);
$num_length = strlen($num);
$levels = (int) (($num_length + 2) / 3);
$max_length = $levels * 3;
$num = substr('00' . $num, -$max_length);
$num_levels = str_split($num, 3);
for ($i = 0; $i < count($num_levels); $i++) {
$levels--;
$hundreds = (int) ($num_levels[$i] / 100);
$hundreds = ($hundreds ? ' ' . $list1[$hundreds] . ' hundred' . ' ' : '');
$tens = (int) ($num_levels[$i] % 100);
$singles = '';
if ( $tens < 20 ) {
$tens = ($tens ? ' ' . $list1[$tens] . ' ' : '' );
} else {
$tens = (int)($tens / 10);
$tens = ' ' . $list2[$tens] . ' ';
$singles = (int) ($num_levels[$i] % 10);
$singles = ' ' . $list1[$singles] . ' ';
}
$words[] = $hundreds . $tens . $singles . ( ( $levels && ( int ) ( $num_levels[$i] ) ) ? ' ' . $list3[$levels] . ' ' : '' );
} //end for loop
$commas = count($words);
if ($commas > 1) {
$commas = $commas - 1;
}
return implode(' ', $words);
}
Solution 3 - Php
In case of using Yii2 you can do this as simple as the following:
$sum = 100500;
echo Yii::$app->formatter->asSpellout($sum);
This prints spelled out $sum
in your app's language.
