Custom PHP script in header

So, I did what you said but for some reason he is not showing it in the correct place.

Example:

What did I do?
1) add my php script to header.php before the closing head tag.
2) added the call for the php script in my secondary header

Example:

But as you can see, the output result is correct but the place needs to move next to the phone number.

Hi Boeckske23,

Try wrapping it in a span with some class. And that file should have somehting like this

ob_start();
$yourcode = ob_get_contents();
ob_end_clean();
return $yourcode;
Can you show us the code from that file?
Best regards,
Victoria

I don’t understand your example

This is the code snippet, adjusted to what you gave me:

/* Openingsuren tonen in header */
add_action('wp_head', 'openingsuren');
function openingsuren(){
?>
	$vandaag = date("l");
	switch($vandaag)
	{
		case 'Monday':
			echo 'Maandag: 14u - 19u';
			break;
		case 'Tuesday':
			echo 'Dinsdag: 14u - 19u';
			break;
		case 'Wednesday':
			echo 'Woensdag: : 14u - 19u';
			break;
		case 'Thursday':
			echo 'Donderdag: 14u - 19u';
			break;
		case 'Friday':
			echo 'Vrijdag: : 14u - 19u';
			break;
		case 'Saturday':
			echo 'Zaterdag: 9u - 17u';
			break;
		case 'Sunday':	
			echo 'Zondag: gesloten';
			break;		
	}
<?php
};

But I get a HTTP error 5000 then.
But actually what I need to know is how to refer to the PHP script in the header location that I marked above.
The result of the script needs to be shown in the ‘Phone Number or small info text’ field, see image below.
How do I call the php script for the result to be shown there.
If you can tell me this, I think thats all I need to know.

Thank you!
I got it working!

Thank you for pointing me in the right direction!

you may close it!
