Function: number_format( )

Here’s a nice function I learned, number_format().
I was looking for a way to add in the commas for the cost of an item since they were exceeding $1,000. The number $100000.00 is hard to read as opposed to $100,000.00. I thought some parsing would be involved, but I should have know that PHP would already have a function for this. ;)
Here’s a code snippet:
<?php
$value = 100000.00;
echo ‘The cost is $’ . number_format($value, 2) . ‘.’;
?>
Having a ’2′ in the parameters tells the function to return 2 decimal spaces. :) Simple huh? The function comes in handy if you ever have to print out the cost of items in a project.
