How can PHP developers efficiently handle input from multiple textareas in a form?

When handling input from multiple textareas in a form, PHP developers can efficiently manage the data by using an array to store the values from each textarea. By naming the textareas with array notation in the form, developers can easily loop through the array in the PHP script to process each textarea's content individually. 

// HTML form with multiple textareas named as an array
<form method="post">
    <textarea name="textareas[]"></textarea>
    <textarea name="textareas[]"></textarea>
    <textarea name="textareas[]"></textarea>
    <input type="submit" name="submit" value="Submit">
</form>

// PHP script to handle input from multiple textareas
if(isset($_POST['submit'])) {
    $textareas = $_POST['textareas'];
    
    foreach($textareas as $textarea) {
        // Process each textarea's content here
        echo $textarea . "<br>";
    }
}
