问题描述



我想要的是:

$ b我已经使用了很多搜索引擎,但是找不到任何有用的函数。
$ b

  100  - > 100 
1000 - > 1,000
142840 - > 142,840



  2023150  - > 2.023M(为了更高的准确性,我还需要3个数字)
5430120215 - > 5.430B

我会完全赞赏任何自定义函数,如果可能的话动态选择限制。



谢谢!

解决方案使用 number_format() code $:

$ $ p $ if($ n <1000000){
//任何小于一百万
$ n_format = number_format($ n);
} else if($ n <1000000000){
//小于十亿
$ n_format = number_format($ n / 1000000,3)。 M;
} else {
//至少十亿
$ n_format = number_format($ n / 1000000000,3)。 B;
}




我会完全理解任何自定义函数的动态如果可能,请选择限制。


如果限制是指小数位数(精度),那很简单:
$ $ p $ b //小于一百万美元b $ b $ n_format = number_format($ n);
} else if($ n <1000000000){
//小于十亿
$ n_format = number_format($ n / 1000000,$ precision)。 M;
} else {
//至少十亿
$ n_format = number_format($ n / 1000000000,$ precision)。 B;
}

返回$ n_format;
}


I've googled this a lot but i can't find any helpful functions based on my queries.

What i want is:

100 -> 100
1000 -> 1,000
142840 -> 142,840

BUT

2023150 -> 2.023M ( i still want 3 additional numbers for more accuracy )
5430120215 -> 5.430B

I would totally appreciate any custom functions to dynamically choose the limit if possible.

Thanks!

解决方案

Use 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';
}

I would totally appreciate any custom functions to dynamically choose the limit if possible.

If "limit" refers to the number of decimal places (the precision), that's easy:

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;
}
