Question

I have a variable in php, print_r:

Array ( 
    [0] => Array ( 
        [0] => Array ( 
            [sum(`Lgsl`.`players`)] => 7769 
        ) 
    )
)

And I have a few such arrays with similiar structure. What is the easiest way to get 7769 number from it without referencing to string-key in latest array.

Answer 1

list ($number) = array_values($arr[0][0]);

The function array_values returns a list of all values with a numeric index, so that you can access the first and only element via index 0. The list keyword can extract array elements into separate variables.
