How can the use of in_array() function improve array handling in PHP?

The in_array() function in PHP can improve array handling by allowing you to easily check if a specific value exists in an array. This can be useful for avoiding duplicate entries, validating user input, or determining if a certain value is present in an array before performing further operations. 

// Example of using in_array() function to check if a value exists in an array
$fruits = ['apple', 'banana', 'orange', 'kiwi'];

if (in_array('banana', $fruits)) {
    echo 'Found banana in the array!';
} else {
    echo 'Banana not found in the array.';
}
