How can field entries from one self-created form be passed to another webpage in PHP?

To pass field entries from one self-created form to another webpage in PHP, you can use the POST method to send the form data to the server and then access that data on the next webpage using the $_POST superglobal array. Simply set the form action attribute to the URL of the next webpage where you want to pass the data.

// Form on first webpage
<form action="second_page.php" method="post">
    <input type="text" name="field1">
    <input type="text" name="field2">
    <input type="submit" value="Submit">
</form>

// second_page.php
<?php
$field1 = $_POST['field1'];
$field2 = $_POST['field2'];

echo "Field 1: " . $field1 . "<br>";
echo "Field 2: " . $field2;
?>
