How can PHP developers effectively use array functions like array_search, array_merge, and array_filter to streamline data processing tasks?

PHP developers can effectively use array functions like array_search, array_merge, and array_filter to streamline data processing tasks by leveraging their specific functionalities. For example, array_search can be used to find the key of a specific value in an array, array_merge can combine multiple arrays into a single array, and array_filter can be used to filter elements based on a callback function. By utilizing these array functions efficiently, developers can simplify complex data manipulation tasks and improve code readability. 

// Example of using array_search to find the key of a specific value in an array
$fruits = ['apple', 'banana', 'orange', 'grape'];
$key = array_search('orange', $fruits);
echo "Key of 'orange' in the array is: " . $key;

// Example of using array_merge to combine multiple arrays into a single array
$numbers1 = [1, 2, 3];
$numbers2 = [4, 5, 6];
$combined = array_merge($numbers1, $numbers2);
print_r($combined);

// Example of using array_filter to filter elements based on a callback function
$numbers = [1, 2, 3, 4, 5];
$filtered = array_filter($numbers, function($num) {
    return $num % 2 == 0;
});
print_r($filtered);
