execute php code within string

Question

This question is just for me to learn from. I can easily resolve it outside of the echo...but there MUST be a way to perform a basic calculation or function call within an echo statement...right?

$CurrentMembershipYear = '2016';

echo '<h2>Two-Year Membership for '.$CurrentMembershipYear.' and '.intval($CurrentMembershipYear)+1.'</h2>';

This should be echoing "Two-Year Membership for 2016 and 2017" but instead is generating errors. Usually I would just pre-calculate the second value before the echo statement and just pass it as a variable...but surely there is a way to put this calculation inline?

Put some parentheses around it. (Look up operator precedence for more info) — Rizier123

never mind...bone-headed brain asleep. Just needed parenthesis...I had only tried curvy braces:

$CurrentMembershipYear = '2016';

echo '<h2>Two-Year Membership for '.$CurrentMembershipYear.' and '.(intval($CurrentMembershipYear)+1).'</h2>';

side note, you dont need intval

I added that because my numeric year is actually stored as a string not a number...so I thought that might have been the issue initially. I will give it a test without the intval and see what happens. Thanks.

its php, its loosely typed, so things like that work (they wouldn't in other languages)

parenthesis should solve it

(intval($CurrentMembershipYear)+1)
