- How to add elements to an empty array in PHP? 9 answers
如何在PHP中向空数组添加元素? 9个答案
$highest = max($data);
$check = array();
$resultype = array();
foreach($data as $key => $value){
if($value === $highest){
echo $key;
//output (t1,t3);
$check = $key;
}
}
echo $check;
//ouput(t3);
Why is it working when I store the $key into a array ?
When I echo in $key in foreach I get what I want (t1,t3) but when I store into and array and output it out side foreach, it only give me (t3).
How do I fix this and store $key into a array with the result I wanted?
当我将$ key存储到数组中时,为什么它工作?当我在foreach中回显$ key时,我得到我想要的东西(t1,t3),但是当我存储到数组并将其输出到foreach时,它只给我(t3)。我如何修复此问题并将$ key存储到具有我想要的结果的数组中?

You're not storing $key in the array, you're assigning it to the variable $check.
你没有在数组中存储$ key,你将它分配给变量$ check。
Try using $check[] = $key;.
尝试使用$ check [] = $ key;。
