formatting - How do I format a number to a dollar amount in PHP

Question

How do you convert a number to a string showing dollars and cents?

eg:
123.45    => '$123.45'
123.456   => '$123.46'
123       => '$123.00'
.13       => '$0.13'
.1        => '$0.10'
0         => '$0.00'

Answer 1

If you just want something simple:

'$' . number_format($money, 2);

number_format()
