Are there specific considerations or best practices to keep in mind when using header(location) for redirection in PHP?

When using header(location) for redirection in PHP, it's important to remember that the header() function must be called before any actual output is sent to the browser. This means that there should be no HTML, whitespace, or even a byte order mark before the header() function is called. Additionally, it's a good practice to include an exit() or die() statement after the header() function to prevent any further code execution. 

<?php
// Ensure no output has been sent before calling header
ob_start();

// Perform any necessary checks or processing
if($condition){
    header("Location: new_page.php");
    exit();
}

// Output any necessary content after header redirection
echo "This is the content of the page";
