How can arrays be effectively utilized in PHP to streamline the evaluation of multiple form inputs?

When dealing with multiple form inputs in PHP, arrays can be effectively utilized to streamline the evaluation process. By naming form inputs with square brackets (e.g., name="input[]"), all values will be submitted as an array. This allows for easy iteration and processing of multiple inputs without the need for individual variable names. 

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $inputs = $_POST['input'];
    
    foreach ($inputs as $input) {
        // Process each input value here
        echo $input . "<br>";
    }
}
?>

<form method="post">
    <input type="text" name="input[]">
    <input type="text" name="input[]">
    <input type="text" name="input[]">
    <input type="submit" value="Submit">
</form>
