Question

如果多维数组中的所有数组在减去两个值时满足特定条件，我想执行特定操作。

什么循环可以帮助我实现这种类型的结果，如下面的代码所示：

$array = Array( 
    [0] => Array("id" => 1, "value1" => 7, "value2" => 10), 
    [1] => Array("id" => 2, "value1" => 6, "value2" => 10), 
    [2] => Array("id" => 3, "value1" => 8, "value2" => 11), 
    [3] => Array("id" => 4, "value1" => 9, "value2" => 12),
    [n] => Array( ...)
);

$val1 = $array[0]['value2'] - $array[0]['value1']; // 10 - 7 = 3
$val2 = $array[1]['value2'] - $array[1]['value1']; // 10 - 6 = 4
$val3 = $array[2]['value2'] - $array[2]['value1']; // 11 - 8 = 3
$val4 = $array[3]['value2'] - $array[3]['value1']; // 12 - 9 = 3
$valn = $array[n]...

if ($val1 < 5 && $val2 < 5 && $val3 < 5 && $val4 < 5 ... && valn < 5){

  //from my example, the answer is TRUE for all
 // Do this action

}else{
 // Do something else

}

Answer 1

$all_less_than_5 = true;
foreach($array as $item){
    if($item['value2'] - $item['value1'] >= 5){
         $all_less_than_5 = false;
         break;
    } 
}
if($all_less_than_5){
    // Do this action
}else{
    // Do something else
}
