在PHP中将1999格式化为19.99 [关闭]

I am trying to format 1999 into 19.99 using PHP number format.

I tried:

$<?php echo number_format('1999',2); ?>

But I received:

$1,999.00 instead of $19.99

Please help!

Simply divide the number by 100

$<?php echo number_format(1999/100,2); ?>

Try with this code:

echo number_format((1999/100),2);

$<?php 
$value = 1999;
echo number_format(($value/100),2); 
?>
