How can array_merge() be utilized to add headers to the beginning of an array in PHP?

To add headers to the beginning of an array in PHP, you can use the array_merge() function to merge the headers array with the existing array. This will add the headers at the beginning of the array without changing the order of the existing elements. 

$headers = ['Header1', 'Header2', 'Header3'];
$data = ['Data1', 'Data2', 'Data3'];

$newArray = array_merge($headers, $data);

print_r($newArray);
