+# Explode Validator
+
+`Zend\Validator\Explode` executes a validator for each item exploded.
+
+## Supported options
+
+The following options are supported for `Zend\Validator\Explode`:
+
+- `valueDelimiter`: Defines the delimiter used to explode the value to an array. It defaults to `,`. If working with an array, this option isn't used.
+- `validator`: Sets the validator that will be executed on each exploded item.
+
+## Basic usage
+
+To validate if every item in an array is into a certain haystack:
+
+```php
+$inArrayValidator = new Zend\Validator\InArray([
+    'haystack' => [1, 2, 3, 4, 5, 6]
+]);
+
+$explodeValidator = new Zend\Validator\Explode([
+    'validator' => $inArrayValidator
+]);
+
+$value  = [1, 4, 6, 8];
+$return = $valid->isValid($value);
+// returns false
+```
+
+The above example returns `true` if all $value items are between 1 and 6.
