I'm assuming you want the english format.
我假设你想要英文格式。
<?php
$number = 1234.56;
// english notation (default)
$english_format_number = number_format($number);
// 1,235
// French notation
$nombre_format_francais = number_format($number, 2, ',', ' ');
// 1 234,56
$number = 1234.5678;
// english notation with a decimal point and without thousands seperator
$english_format_number = number_format($number, 2, '.', '');
// 1234.57
?>

$number = 1234.56;
//Vietnam notation(comma for decimal point, dot for thousand separator)
$number_format_vietnam = number_format($number, 2, ',', '.');
//1.234,56

Often, if a number is big enough to have commas in it, you might want to do without any numbers after a decimal point - but if the value you are showing could ever be small, you would want to show those decimal places. Apply number_format conditionally, and you can use it to both add your commas and clip off any irrelevant post-point decimals.
通常，如果一个数字大到足以在其中包含逗号，您可能希望在小数点后没有任何数字 - 但如果您显示的值可能很小，您可能希望显示这些小数位。有条件地应用 number_format，您可以使用它来添加逗号并剪掉任何不相关的后点小数。
if($measurement1 > 999) {
//Adds commas in thousands and drops anything after the decimal point
$measurement1 = number_format($measurement1);
}
Works well if you are showing a calculated value derived from a real world input.
如果您显示的是从真实世界输入中导出的计算值，则效果很好。
