Are there any specific PHP functions or techniques that can help with handling arrays effectively?

When working with arrays in PHP, there are several built-in functions and techniques that can help with handling them effectively. One common technique is using foreach loops to iterate over arrays and perform operations on each element. Additionally, functions like array_push, array_pop, array_shift, and array_unshift can be used to add or remove elements from arrays. Another useful function is array_merge, which can be used to merge two or more arrays together. 

// Example of using foreach loop to iterate over an array
$numbers = [1, 2, 3, 4, 5];
foreach ($numbers as $number) {
    echo $number . " ";
}

// Example of using array_push to add elements to an array
$fruits = ['apple', 'banana'];
array_push($fruits, 'orange', 'kiwi');

// Example of using array_merge to merge two arrays
$vegetables = ['carrot', 'broccoli'];
$food = array_merge($fruits, $vegetables);
