代码很简洁,也很简单,就不多废话了。

复制代码 代码如下:

/**
 * 去除多余的0
 */ 
function del0($s) 

    $s = trim(strval($s)); 
    if (preg_match('#^-?\d+?\.0+$#', $s)) { 
        return preg_replace('#^(-?\d+?)\.0+$#','$1',$s); 
    }  
    if (preg_match('#^-?\d+?\.[0-9]+?0+$#', $s)) { 
        return preg_replace('#^(-?\d+\.[0-9]+?)0+$#','$1',$s); 
    } 
    return $s; 
}

小伙伴们自由扩展下,可以做很多事情,希望大家能够喜欢。
