How do I fix this error in PHP: "A non well formed numeric value encountered"
php, strtotime
Solution
The second parameter of `strtotime` expects a timestamp, not a string. See the manual on `strtotime`.
You can use `strtotime` again on your second parameter to get what you want:
echo gmdate('Y-m-d H:i:s',strtotime('+7 days',strtotime('2035-01-01 00:00:00')));
Problem
