I have an array shown below and this line in my php controller:

 if(count($crew_rows != 0)){

Bluehost upgraded to php7.2 and I now get the following error:

Warning: count(): Parameter must be an array or an object that implements Countable in /home2/sailwbob/public_html/skipper/public/crew.php on line 1885

How do I fix this? (without reverting to an earlier version of php)

    Move the comparision outside of the function call. Or remove it alltogether, 0 is falsey. Commented Sep 15, 2019 at 20:42

Reset to default

You have the closing parenthesis in the wrong place in your if statement. It should look like this: 

if (count($crew_rows) != 0) {

Right now, you're passing the result of $crew_rows != 0 to the count() function - a boolean, rather than an array.

Even not neccessary to compare at all. If count() is > 0, the expression is true. if (count($crew_rows)) { ... }.
@Alex P, thanks. Thats be in my code for 5 years and this is the first time I got an error warning!
