将字符串转换为整数将返回2147483647

问题描述

很多其他人似乎都遇到了这个问题，但通常与MySQL数据类型有关.

Plenty of others seem to have had this problem, but usually associated with an MySQL datatype.

我正在尝试将String转换为Integer，如下所示:

I'm trying to convert a String to an Integer like this:

$adGroupId  = '5947939396';
$adGroupId  = intval($adGroupId)

但是返回的整数是2147483647，与输入的字符串无关.

However the Integer returned is 2147483647, irrespective of the string input.

推荐答案

该数字太大，无法容纳整数数据类型(如上面所示，最大整数值为2147483647). 将其转换为浮点型将起作用:

That number is too big to fit in an integer data type (the max integer value is 2147483647 as seen above). Converting it to a float instead will work:

$adGroupId  = '5947939396';
$adGroupId  = floatval($adGroupId)
