Question

I Need to rework an PHP array of time zones. I am trying to move the american timezones to the top of the array. How do you single out iterations and either remove them or reorder the array?

Answer 1

assuming you know the exact values of americanTimezones and stored those in an array $moveUsToTheTop, and that the current disordered array is $timezones, the following should reposition those values at $moveUsToTheTop at the beginning of the array

foreach ($moveUsToTheTop as $americanTimezone){
    $pos = array_search($americanTimezone, $timezones);
    unset($timezones[$pos]);
    array_unshift($timezones, $americanTimezone);
}
