How to remove outer array in a multi-dimensional array in PHP and create a new array or make modifications in the same array?

Question

I've a multidimensional array titled $event_details as follows :

I want to remove the outermost array(i.e. first among the multidimensional array) and needs the final array exactly as below :

The second level array elements should come outside and the indexing should be from 0,1,2,3,....and so on.

You can do this thing to the same multi dimensional array $event_details or can create a new one as per the optimality and efficiency of the code.

Wont doing that loose some useful information about when these events takes place — RiggsFolly

@RiggsFolly:It will be fine for me even if the event information regarding the time vanishes from array. — PHPLover

You can do it using array_reduce()

$result = array_reduce($event_details, 'array_merge', array());

You can easily loop over your array with two loops and create a new array out of it. I would not bother manipulating the old array. Like so:

$newArray = array();
foreach($event_details as $day) {
    foreach($day as $singleEntry) {
        $newArray[] = $singleEntry;
    }
}

The $newArray variable will afterwards contain the array you are looking for.

However, next time you ask a question, you should also include the things that you have already tried, or at least some approaches that you thought of but failed with, or something like that.

And P.S.: The indices will be increasing integers in your new array automatically, just like you wanted.

Thanks for your answer and recommendation but I haven't seen usage of any of the built-in array functions that are available in PHP.

Well there is no usage of it. Why would you need it? As you can see the task is pretty simple

If I'm not mistaken, couldn't a simple way like this will work? (untested)

$event_details = array (...);
$newArray = $event_details["today"];

Just simply copy the array from the point of entry "today" to the $newArray
