# Convert numbers to words

Numbers are great, sure, but sometimes you need to spell them out … and if you think the possibility for that to happen is slim, invoices and checks for example need to have the ammount in both numbers and letters (in most countries).

That’s why a script to convert numbers to words (to spell numbers) can come in handy.

``````
function number_to_words (\$x)
{
global \$nwords;
if(!is_numeric(\$x))
{
\$w = '#';
}else if(fmod(\$x, 1) != 0)
{
\$w = '#';
}else{
if(\$x < 0)
{
\$w = 'minus ';
\$x = -\$x;
}else{
\$w = '';
}
if(\$x < 21)
{
\$w .= \$nwords[\$x];
}else if(\$x < 100)
{
\$w .= \$nwords[10 * floor(\$x/10)];
\$r = fmod(\$x, 10);
if(\$r > 0)
{
\$w .= ' '. \$nwords[\$r];
}
} else if(\$x < 1000)
{

\$w .= \$nwords[floor(\$x/100)] .' hundred';
\$r = fmod(\$x, 100);
if(\$r > 0)
{
\$w .= ' '. number_to_words(\$r);
}
} else if(\$x < 1000000)
{
\$w .= number_to_words(floor(\$x/1000)) .' thousand';
\$r = fmod(\$x, 1000);
if(\$r > 0)
{
\$w .= ' ';
if(\$r < 100)
{
\$w .= ' ';
}
\$w .= number_to_words(\$r);
}
} else {
\$w .= number_to_words(floor(\$x/1000000)) .' million';
\$r = fmod(\$x, 1000000);
if(\$r > 0)
{
\$w .= ' ';
if(\$r < 100)
{
\$word .= ' ';
}
\$w .= number_to_words(\$r);
}
}
}
return \$w;
}

I noticed a couple bugs you may or may not want to fix.

Some spelling errors:
1. ‘eightteen’ should be ‘eighteen’
2. ‘fourty’ should be ‘forty’
3. ‘eigthy’ should be ‘eighty’

A grammatical error:
1. Two digit numbers greater than 20 and not ending in zero should be separated by a hyphen, not a space. i.e. ‘twenty one’ should be ‘twenty-one’, ‘eighty nine’ should be ‘eighty-nine’, etc. (http://en.wikipedia.org/wiki/List_of_numbers#Small_numbers)
