我的切换案例允许查找具有两个特定值的表。这是我想做的：
foreach ($array as $key => $value) {
switch($value) {
case "C":
case "D":
//Take all key from "C" until I come across a second value "C" or "D"
}
}
这是一个例子：
$array =
(
[53] => q
[61] => f
[74] => s
[87] => C
[19] => D
[101] => e
[22] => C
[13] => h
)
结果：“ 87 19 101”
这是一个奇怪的逻辑，但这应该可以工作：
//Triggers are the flags that trigger opening or close of filters
$triggers = array('C', 'D');
$filtered = [];
$stack = [];
foreach($array as $k => $v) {
//If the trigger is opened and I see it again, break the loop
if (in_array($v, $stack)) {
break;
}
//If we sees the trigger OR the stack is not empty (we are opened)
//continuously pull the keys out
if (in_array($v, $triggers) || !empty($stack)) {
$stack[] = $v;
$filtered[] = $k;
}
}
的输出是
Array
(
[0] => 87
[1] => 19
[2] => 101
)
