What are some strategies for merging and processing data from multiple arrays in PHP before displaying it in a foreach loop?

When merging and processing data from multiple arrays in PHP before displaying it in a foreach loop, one strategy is to use functions like array_merge() or array_merge_recursive() to combine the arrays. Additionally, you can use array_map() or array_walk() to process the data before looping through it with a foreach loop. 

// Merge multiple arrays
$array1 = [1, 2, 3];
$array2 = [4, 5, 6];
$mergedArray = array_merge($array1, $array2);

// Process the merged array
$processedArray = array_map(function($item) {
    return $item * 2;
}, $mergedArray);

// Display the processed data in a foreach loop
foreach ($processedArray as $item) {
    echo $item . "<br>";
}
