PHP: 如何使用 if-else 语句更改数组中的值?
原标题:PHP: How to change values in an array using if-else statement?

假设我有一个有10个元素的阵列,例如: 阵列(1,0,0,0,0,0,0,0,0,0,0,1)

如何使用 if-elee 语句来评估数组的元素 。 说如果值是 之一, 我希望有 " 是 " 输出, 如果是 0, 那么就是 NO 。 我肯定我会使用一个循环语句来评估每个单元格或元素。 另外, 如果一个元素的值为 1. 5 或任何浮动数字, 我也会希望它被替换为 " 是 " 。

任何提示都感激不尽 事先谢谢

问题回答

只要绕过阵列检查元素

 if(!$arr[$i]) echo "NO"
 else echo "Yes"

你已经有办法了,你到底需要什么?
