How can PHP beginners effectively utilize array functions in their code?

PHP beginners can effectively utilize array functions by familiarizing themselves with common functions like `array_push()`, `array_pop()`, `array_shift()`, `array_unshift()`, `array_merge()`, `array_slice()`, `array_key_exists()`, `array_search()`, and `array_unique()`. These functions can help manipulate arrays, search for specific values, and remove duplicates efficiently. 

// Example of utilizing array functions in PHP code
$fruits = ['apple', 'banana', 'orange'];

// Adding an element to the end of the array
array_push($fruits, 'grape');

// Removing the last element from the array
array_pop($fruits);

// Adding an element to the beginning of the array
array_unshift($fruits, 'kiwi');

// Removing the first element from the array
array_shift($fruits);

// Merging two arrays
$moreFruits = ['pineapple', 'strawberry'];
$allFruits = array_merge($fruits, $moreFruits);

// Searching for a value in the array
$index = array_search('banana', $allFruits);

// Checking if a key exists in the array
if(array_key_exists($index, $allFruits)) {
    echo "Found at index: " . $index;
}

// Removing duplicates from the array
$uniqueFruits = array_unique($allFruits);
