[](#usage)

#### Simple

[](#simple)

A simple loop over an array.

```
use Enzyme\Loopy\Each;

$array = [1, 2, 3];

Each::shallow()->begin($array, function($bag) {
    echo $bag->value() . ', ';
});
```

The above will output `1, 2, 3, `

#### Deep

[](#deep)

A deep loop over a multidimensional array.

```
use Enzyme\Loopy\Each;

$array = [1, 2, 3, 4 => [4, 5, 6]];

Each::deep()->begin($array, function($bag) {
    echo $bag->value() . ', ';
});
```

The above will output `1, 2, 3, 4, 5, 6, `

#### Filtered

[](#filtered)

A loop over a filtered array.

```
use Enzyme\Loopy\Each;
use Enzyme\Loopy\Filters\SkipNulls;

$array = [1, 2, null, 4, 5];

Each::deep(new SkipNulls)->begin($array, function($bag) {
    echo $bag->value() . ', ';
});
```

The above will output `1, 2, 4, 5, `

Bags

The `$bag` object passed to the callback function generally contains the follow information.

KeyValueDescriptionkey()KeyThe enumerable objects key for the given pass.value()ValueThe enumerable objects value for the given pass.cycle()Current cycle (0 based)How many times around the entire object the looper has gone.depth()Current depth (0 based)The current depth of the pass, for multidimensional arrays.index()Current index (0 based)The current index, in this case index is really a count of the number of items encountered so far.Filters
=======

[](#filters)

FilterDescriptionSkipNullsWill skip over any values which are null.RegexWill test value against the supplied regular expression.EqualWill test value for equality against the given rule.
