How can PHP headers affect the integration of scripts into a template?

PHP headers can affect the integration of scripts into a template by controlling the HTTP response sent to the browser. If headers are set improperly or conflicting with other headers, it can lead to unexpected behavior or errors in script integration. To ensure smooth integration, make sure to set headers before any output is sent to the browser, avoid duplicate header declarations, and check for any conflicts with existing headers. 

// Set headers before any output
header('Content-Type: text/html');

// Include scripts or template files here
include 'header.php';
include 'content.php';
include 'footer.php';
