文章提供的这个PHP 把科学计数法转换为原始数字字符串函数非常的好用,希望能帮助到各位朋友吧,代码如下:

function NumToStr($num){ 
    if (stripos($num,'e')===false) return $num; 
    $num = trim(preg_replace('/[=\'"]/','',$num,1),'"');//出现科学计数法,还原成字符串 
    $result = ""; 
    while ($num > 0){ 
        $v = $num - floor($num / 10)*10; 
        $num = floor($num / 10); 
        $result   =   $v . $result; 
    }//开源代码phprm.com 
    return $result; 
}
