我已经在Google上进行了很多搜索，但根据查询找不到任何有用的功能。
我想要的是：
100 -> 100 1000 -> 1,000 142840 -> 142,840
但
2023150 -> 2.023M ( i still want 3 additional numbers for more accuracy ) 5430120215 -> 5.430B
如果可以的话，我非常感谢任何自定义函数可以动态选择限制。
谢谢！
用途number_format()：
number_format()
if ($n < 1000000) { // Anything less than a million $n_format = number_format($n); } else if ($n < 1000000000) { // Anything less than a billion $n_format = number_format($n / 1000000, 3) . 'M'; } else { // At least a billion $n_format = number_format($n / 1000000000, 3) . 'B'; }
如果“限制”是指小数位数（精度），则很简单：
function custom_number_format($n, $precision = 3) { if ($n < 1000000) { // Anything less than a million $n_format = number_format($n); } else if ($n < 1000000000) { // Anything less than a billion $n_format = number_format($n / 1000000, $precision) . 'M'; } else { // At least a billion $n_format = number_format($n / 1000000000, $precision) . 'B'; } return $n_format; }
