如何在if条件下检查数组值？ [英] How to check the array value in if condition?

问题描述

我正在使用codeignator，并且正在数组中获得多个值。

I am using codeignator and I am getting the multiple value in the array.

$status = $this->input->post('Status[]');
print_r($status);

输出为

Array ( 
[0] => 1 
[1] => 7 
[2] => 8 
[3] => 7 
)
It will increase and value will be duplicate like 7.

现在，我必须检查每个数组的值。所以我尝试了

Now I have to check each array value. so I tried

if (($status=1)||($status=3) || ($status=6) || ($status=8)|| ($status=9)) {
    $remark = $this->input->post('remark[]');
   }
   else{$remark="";}

if(($status=2)||($status=4) || ($status=5)){
    $reasonDate = $this->input->post('reasonDate[]');
    $remark = $this->input->post('remark[]');
     }
  else{
       $reasonDate="";
       $remark="";
}

if($status=7){
   $reasonA = $this->input->post('reasonA[]');
   $reason = $this->input->post('reason[]');
   }
   else{
        $reasonAmt="";
        $reason="";
 }

您能帮我如何通过if条件检查数组值吗？我是否需要使用in_array或其他任何方法？

Can you help me out how to check the array value with if condition? Should I need to use in_array or any other way?

推荐答案

目前尚不清楚100％您正在尝试做什么，所以希望以下答案之一会有所帮助。

It's not 100% clear what you're attempting to do, so hopefully one of the answers below will help.

如果您要遍历数组中的每个状态并检查其是否为特定值，则可以使用foreach循环。看起来像这样：

If you're trying to go through each status in the array and check if it is a specific value, you can use a foreach loop. It would look something like this:

$statuses = [1, 7, 8, 7];

foreach ($statuses as $status) {
    if ($status=1 || $status=3 || $status=6 || $status=8 || $status=9) {
        // Do something
    }
    else {
        // Do something else
    }
    // etc...
}

如果您要检查数组中至少一个状态是否为特定状态值，则可以使用Dave建议的 in_array函数。看起来像这样：

If you're trying to check if at least one of the statuses in the array is a specific value, you can use the "in_array" function like Dave suggested. It would look something like this:

$statuses = [1, 7, 8, 7];

if (in_array(1, $statuses) || in_array(3, $statuses) || in_array(6, $statuses) || in_array(8, $statuses) || in_array(9, $statuses)) {
    // Do something
}
else {
    // Do something else
}
// etc...

您可以查找 in_array函数的文档此处。

You can look up the documentation for the "in_array" function here.
