What is the recommended way to pass input content from an HTML input box to a new page using a link in PHP?

To pass input content from an HTML input box to a new page using a link in PHP, you can use the GET method to send the input data as query parameters in the URL. This way, the input content will be accessible on the new page through the $_GET superglobal array. You can then retrieve the input content using the key associated with the input box in the $_GET array.

<!-- HTML form with input box -->
<form action="newpage.php" method="get">
    <input type="text" name="inputContent">
    <input type="submit" value="Submit">
</form>

<!-- newpage.php -->
<?php
if(isset($_GET['inputContent'])){
    $inputContent = $_GET['inputContent'];
    echo "Input content: " . $inputContent;
}
?>
