PHP在1个变量中存储多个整数变量？ [英] PHP storing multiple integer variables in 1 variable?

问题描述

我正在创建一个php脚本，它创建一个长度为7位且不包含0的随机数，唯一的问题是我必须调用函数rand 7次并存储在a中生成的每个数字不同的变量，但我想知道如何将这些数字放在变量中而不是将它们加在一起

I'm creating a php script which creates a random number which is 7 digits long and doesn't contain 0's, the only problem with this is that I have to call the function rand 7 times and store every number generated in a different variable, but I was wondering how I could put these numbers together in a variable instead of adding them together

$ security_number = $ 1&& $ 2&& $ 3等等。

$security_number = $1&&$2&&$3 and so on.

提前感谢。

推荐答案

我想我知道你想要实现的目标。你需要一种你真正想要七个字符的数字串的心态。例如，如果您的号码是0028172，如果它被存储为数字，那么就像数字计算器一样，它将显示为28172，除非您使用字符串格式。

I think I know what you are trying to achieve. You need the mindset that you actually want a seven character string of digits. For example, if your number was 0028172, if it is stored as a number then just like a digital calculator it will be displayed as 28172 unless you use string formatting.

如果你已经有代码创建个别数字，只需使用连接：

If you already have code creating the individual digits, simply use concatenation:

$ securitycode = $ digit1。 $ digit2。 $ digit3。 $ digit4。 $ digit5。 $ digit6。 $ digit7;

$securitycode = $digit1 . $digit2 . $digit3 . $digit4 . $digit5 . $digit6 . $digit7;

希望这可以帮到你。
