What are best practices for sending content from a text field to multiple PHP files?

When sending content from a text field to multiple PHP files, it is best to use a form submission method like POST to securely transmit the data. You can then access the submitted data in each PHP file using the $_POST superglobal array. Make sure to sanitize and validate the input data to prevent security vulnerabilities. 

// Form submission in HTML
<form method="post" action="file1.php">
    <input type="text" name="content">
    <button type="submit">Submit</button>
</form>

// file1.php
<?php
if(isset($_POST['content'])) {
    $content = $_POST['content'];
    // Sanitize and validate the input data
    // Process the data or pass it to another PHP file
    include 'file2.php';
}
?>

// file2.php
<?php
// Access the submitted data from file1.php
if(isset($content)) {
    // Process the data further
}
?>
