+# `pad()`
+
+The pad method will fill the array with the given value until the array reaches the specified size. This method
+behaves like the [array_pad](https://secure.php.net/manual/en/function.array-pad.php) PHP function.
+
+To pad to the left, you should specify a negative size. No padding will take place if the absolute value of the given size is less than or equal to the length of the array:
+
+```js
+const collection = collect(['A', 'B', 'C']);
+
+let filtered = collection.pad(5, 0);
+
+filtered.all();
+
+// ['A', 'B', 'C', 0, 0]
+
+filtered = collection.pad(-5, 0);
+
+filtered.all();
+
+// [0, 0, 'A', 'B', 'C']
+```
