The following printf()call should work for you:

以下printf()电话应该适合您：

<?php printf("%.2f", $price); ?>

The documentation for this syntax is best described on the sprintf()page.

此语法的文档最好在sprintf()页面上进行描述。

number_formatis your best bet.

number_format是您最好的选择。

string number_format ( float $number , int $decimals = 0 , string $dec_point = '.' , string $thousands_sep = ',' )

Example:

例子：

<?php echo number_format(1.0000, 2, '.', ','); ?>
