Call php variable array name in foreach loop

Question

I have arrays with the following names: $MyMondayClasses, $MyTuesdayClasses, $MyWednesdayClasses, $MyThursdayClasses, $MyFridayClasses

And I have an array for days of the week: $days = array('Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday');

I want to loop through the days of the week and then run the appropriate array, but I'm not sure how to refer to the variable to make:

foreach($days as $value){
    foreach($My{$value}Classes as $ClassKey => $ClassVar){
        some code goes here
    }
}

I used to use eval for this sort of thing, but understand that's not best practice. Anyway, the above code isn't working.

Why don't you just have one class that you pass the day of the week to? I presume the days of the week classes will be similar. — karmafunk

have you considered constructing your $MyDAYClasses arrays in another array with the days for indices from the beginning ? e.g. classes = array('Monday'=> $MyMondayClasses), ...); That way when you want to look them up, you can find them easily. — dnagirl

Sounds not very clever.

Why don’t you just have one array, with 'monday', 'tuesday' etc. as keys - and then have your data arrays for each day under that key …?

Does not make sense .. you should use array but if you insist you can try :

foreach ( $days as $value ) {
    $name = sprintf("My%sClasses", $value);
    if (! isset(${$name})) { // the boss asked
        continue;
    }
    foreach ( ${$name} as $ClassKey => $ClassVar ) {
        // play some ball
    }
}
