In Symfony, you can easily merge arrays using PHP's built-in functions. One common method to merge arrays is using the `array_merge()` function. Below is an example of how to merge two arrays in Symfony:
<?php
$array1 = ['apple', 'banana'];
$array2 = ['orange', 'grape'];
// Merging the arrays
$mergedArray = array_merge($array1, $array2);
print_r($mergedArray); // Outputs: Array ( [0] => apple [1] => banana [2] => orange [3] => grape )
?>
