How can using arrays in PHP affect the comparison of values in IF clauses?

When comparing values in IF clauses with arrays in PHP, you need to use functions like `in_array()` or `array_search()` to check if a value exists within the array. Directly comparing arrays using `==` or `===` will not work as expected. By using array functions, you can properly check if a value is present in an array and make decisions based on that. 

<?php
// Example of comparing values in IF clauses with arrays
$fruits = ['apple', 'banana', 'orange'];

// Incorrect way to compare values in an array
if ($fruits == 'apple') {
    echo 'Apple is in the array';
}

// Correct way to check if a value exists in an array
if (in_array('apple', $fruits)) {
    echo 'Apple is in the array';
}
?>
