I have a slight improvement on the roman numerals function:
<?php
function ar_rom($ar,$br="\r\n"){
$lin='';
$num='';
$rom=array(
array('no'=>1000000, 'lin'=>'_',
'num'=>'M'),
array('no'=>900000, 'lin'=>'_',
'num'=>'CM'),
array('no'=>500000, 'lin'=>'_',
'num'=>'D'),
array('no'=>400000, 'lin'=>'_',
'num'=>'CD'),
array('no'=>100000, 'lin'=>'_',
'num'=>'C'),
array('no'=>90000, 'lin'=>'_',
'num'=>'XC'),
array('no'=>50000, 'lin'=>'_',
'num'=>'L'),
array('no'=>40000, 'lin'=>'_',
'num'=>'XL'),
array('no'=>10000, 'lin'=>'_',
'num'=>'X'),
array('no'=>9000, 'lin'=>'_',
'num'=>'IX'),
array('no'=>5000, 'lin'=>'_',
'num'=>'V'),
array('no'=>4000, 'lin'=>'_',
'num'=>'IV'),
array('no'=>1000, 'lin'=>' ',
'num'=>'M'),
array('no'=>900, 'lin'=>' ',
'num'=>'CM'),
array('no'=>500, 'lin'=>' ',
'num'=>'D'),
array('no'=>400, 'lin'=>' ',
'num'=>'CD'),
array('no'=>100, 'lin'=>' ',
'num'=>'C'),
array('no'=>90, 'lin'=>' ',
'num'=>'XC'),
array('no'=>50, 'lin'=>' ',
'num'=>'L'),
array('no'=>40, 'lin'=>' ',
'num'=>'XL'),
array('no'=>10, 'lin'=>' ',
'num'=>'X'),
array('no'=>9, 'lin'=>' ',
'num'=>'IX'),
array('no'=>5, 'lin'=>' ', 'num'=>'V'),
array('no'=>4, 'lin'=>' ',
'num'=>'IV'),
array('no'=>1, 'lin'=>' ', 'num'=>'I'),
);
foreach($rom as $k => $v){
while($ar>=$v['no']){
$ar=$ar-$v['no'];
$lin.=$v['lin'];
$num.=$v['num'];
}
}
if(strpos($lin, '_')===FALSE){
return $num;
}else{
return $lin.$br.$num;
}
}
echo ar_rom(1957938,'<br>');
?>
in browser returns:
____
MCMLVMMCMXXXVIII
(Line above = Number X 1000)
This is good for numbers up to about 10 million, otherwise you get:
______________________________________________
MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM etc.
(normally the lines would be flush, if dealing with numbers over 3000 make sure to use Lucida
Console or some other font where all the chars are the same length)
