I have read that money_format is not available on windows, and on some Linux distributions (i.e. BSD 4.11 variants). But I want to write cross-platform library using normal function, when available and using this workaround when not, so my library will be able to run on every PHP-based web server.
Is there any simple solution to check whether built-in function is available and if not to include the solution from above?
The function money_format() is only defined if the system has strfmon capabilities. For example, Windows does not, so money_format() is undefined in Windows.
So you can use this php code:
setlocale(LC_ALL, ''); // Locale will be different on each system.
$amount = 1000000.97;
$locale = localeconv();
echo $locale['currency_symbol'], number_format($amount, 2, $locale['decimal_point'], $locale['thousands_sep']);
With this you can write code that is actually portable instead of relying on operating system features. Having the money_format function available in PHP without it being an extension is pretty stupid. I don’t see why you would want to create inconsistencies like this between different operating systems in a programming language
The money_format() is not worked on Windows machine. So here is your solution for Indian currency format:
<?php
function inr_money_format($number){
$decimal = (string)($number - floor($number));
$money = floor($number);
$length = strlen($money);
$delimiter = '';
$money = strrev($money);
for($i=0;$i<$length;$i++){
if(( $i==3 || ($i>3 && ($i-1)%2==0) )&& $i!=$length){
$delimiter .=',';
}
$delimiter .=$money[$i];
}
$result = strrev($delimiter);
$decimal = preg_replace("/0\./i", ".", $decimal);
$decimal = substr($decimal, 0, 3);
if( $decimal != '0'){
$result = $result.$decimal;
}
return $result;
}
?>
