在php中更改0的格式

Question

有没有办法在PHP中将0格式化为空格？我知道如何改变正负值的格式而不是0，使用类似的东西：

$final = number_format($number,2); 

Answer 1

$final = $number ? number_format($number,2) : ""; 

Answer 2

这应该适合你：

<?php

    $number = 3.12;
    if (substr(number_format($number,2), -2) == 0)
        $final = $number;
    else
        $final = number_format($number,2);
    echo $final;


?>

输入/输出：

//number = 3.00
//Output = 3

//number = 3.12
//output = 3.12
