用INR方法格式化价格

Question

我有一段代码，将数字格式化为印度卢比价格(₹1.00/-，₹10,00,000.00/-等):

function price_format($num,$type = 1){
$num_full = number_format($num,2);
if (strpos($num, '.') !== false) {
$num = substr($num_full, 0, strpos($num_full, "."));
}

if($type == 1){ // '₹10,00,000.00/-'
$explrestunits = "" ;
if(strlen($num)>3) {
$lastthree = substr($num, strlen($num)-3, strlen($num));
$restunits = substr($num, 0, strlen($num)-3); // extracts the last three digits
$restunits = (strlen($restunits)%2 == 1)?"0".$restunits:$restunits; // explodes the remaining digits in 2's formats, adds a zero in the beginning to maintain the 2's grouping.
$expunit = str_split($restunits, 2);
for($i=0; $i<sizeof($expunit); $i++) {
// creates each of the 2's group and adds a comma to the end
if($i==0) {
$explrestunits .= (int)$expunit[$i].","; // if is first value , convert into integer
} else {
$explrestunits .= $expunit[$i].",";
}
}
$thecash = "₹".$explrestunits.$lastthree.substr($num_full, -3, strpos($num_full, "."))."/-";
} else {
$thecash = "₹".$num.substr($num_full, -3, strpos($num_full, "."))."/-";
}
return $thecash; // writes the final format where $currency is the currency symbol.
}
}

对于下面的测试，没有给出预期的结果。

echo price_format(1)."<br />";
echo price_format(10)."<br />";
echo price_format(84289.35);

现场演示

此外，代码是开放的，如果有人想让这个代码更清晰和简短，我很高兴

设置为$thecash时，不使用strpos。大小写敏感文档

使用number_format()作为:number_format((float)$num,2,'.','');

工作代码:

function price_format($num,$type = 1){
$num_full = number_format((float)$num,2,'.','');
if (strpos($num, '.') !== false) {
$num = substr($num_full, 0, strpos($num_full, "."));
}

if($type == 1){ // '₹10,00,000.00/-'
$explrestunits = "" ;
if(strlen($num)>3) {
$lastthree = substr($num, strlen($num)-3, strlen($num));
$restunits = substr($num, 0, strlen($num)-3); // extracts the last three digits
$restunits = (strlen($restunits)%2 == 1)?"0".$restunits:$restunits; // explodes the remaining digits in 2's formats, adds a zero in the beginning to maintain the 2's grouping.
$expunit = str_split($restunits, 2);
for($i=0; $i<sizeof($expunit); $i++) {
// creates each of the 2's group and adds a comma to the end
if($i==0) {
$explrestunits .= (int)$expunit[$i].","; // if is first value , convert into integer
} else {
$explrestunits .= $expunit[$i].",";
}
}
$thecash = "₹".$explrestunits.$lastthree.substr($num_full, -3)."/-";
} else {
$thecash = "₹".$num.substr($num_full, -3)."/-";
}
return $thecash; // writes the final format where $currency is the currency symbol.
}
}
echo price_format(1).PHP_EOL;
echo price_format(10).PHP_EOL;
echo price_format(84289.35);
