There is an array of rules:

```
array
(
[0] = & gt; Array.
(
[Value] = & gt; thirty
[description] = & gt; 30 seconds
)
[1] = & gt; Array.
(
[Value] = & gt; 45.
[description] = & gt; 45 seconds
)
[2] = & gt; Array.
(
[Value] = & gt; 60.
[description] = & gt; 1 minute
)
[3] = & gt; Array.
(
[Value] = & gt; 120.
[description] = & gt; 2 minutes
)
)
```

and I get a variable $ rule_value (for example $ rule_value = 60)

and you need to check if there is a number 60 in this array in the VALUE key.

Is it possible to implement it in 1 line without cycles?

Paw to Array_Map, Array_Search

But not yet. Please tell me

## Answer 1, Authority 100%

so:

```
array_filter ($ ARR, FUNCTION ($ A) {
RETURN $ A ["VALUE"] == 60;
});
```

## Answer 2, Authority 17%

Even I don’t know, try array_walk, array_walk_recursive something from this but it seems to me it’s easier to pass an array once and say to replace the keys to value

## Answer 3

If possible, form an array

```
$ ar = array (
[30] = & gt; '30 seconds',
[60] = & gt; '1 minute',
[120] = & gt; '2 minutes'
)
// Value will become the key of the array.
//Farther:
if (Array_Key_exists ($ Rule_Value, $ Ar)) {
// Apply the key to the cell.
echo $ ar [$ rule_value];
}
```

## Answer 4

`$ key = array_search ($ rule_value, array_column ($ array, 'value')); `
