  • Hi,

    The error message “Warning: usort() expects parameter 2 to be a valid callback, function ‘date_compare’ not found or invalid function name” indicates that there is an issue with the second parameter passed to the usort() function.

    The usort() function is used to sort an array using a user-defined comparison function. The second parameter of the usort() function should be a valid callback function that can be used to compare the elements of the array.

    In this case, the error message suggests that the function named “date_compare” is either not defined or has an invalid function name.

    To resolve this error, you need to make sure that the function named “date_compare” is defined and has a valid function name. You should check the spelling of the function name and make sure that the function is defined in the correct file and in the correct scope.

    You should also ensure that the function is properly defined as a callback function. A valid callback function must accept two parameters and return an integer value that represents the result of the comparison between the two parameters.
