Display message according to the priority wise

Question

i have an array like

Array ( [0] => Array ( [msg] => xyx 
                       [social] =>xxx 
                       [priority] => 1 ) 
        [1] => Array ( [msg] => vvv 
                       [social] => 
                       [priority] => 2 ) 
        [2] => Array ( [msg] => hhh 
                       [social] => 
                       [priority] => 2 ) 
        [3] => Array ( [msg] => rrr 
                       [social] => jws 
                       [priority] => 2 ) 
        [4] => Array ( [msg] => hhhh. 
                       [social] => fff 
                       [priority] => 3 ) 
)

i need to display this msg priority wise. The condition is msg will be changed on each page load. I have used shuffle() but it's not proper.

Is it possible to change the sequence of the array ??

is this array going to be same on each page, and which message need to show first `priority=1` or `priority=4` — Alive to die - Anant, Feb 24 '16 at 16:07
"Obviously"... Sure, obvious... – Sure it's possible to change the sequence of items in an array, it's called *sorting*. — deceze, Feb 24 '16 at 16:12
on first page load it will be display 1 by using array short ... whats next ?? only one msg can be displayed — codeBloger, Feb 24 '16 at 16:14
@deceze on sccond load it will be p2 ??? so dont mark as duplicate without reading the question properly also .. its already sorted according to priority wise — codeBloger, Feb 24 '16 at 16:15
So on first page load the first message, next page load second message etc... then on the sixth page load it starts from the beginning...? — deceze, Feb 24 '16 at 16:19
should i have to count the page load ??? isnt thir any other way to shuffle according to the priotywise — codeBloger, Feb 24 '16 at 16:22

finally what i have done is :

Array ( [0] => Array ( [msg] => xyx 
                       [social] =>xxx 
                       [priority] => 1 ) 
[0] => Array ( [msg] => xyx 
                       [social] =>xxx 
                       [priority] => 1 ) 
[0] => Array ( [msg] => xyx 
                       [social] =>xxx 
                       [priority] => 1 ) 
[0] => Array ( [msg] => xyx 
                       [social] =>xxx 
                       [priority] => 1 ) 
[0] => Array ( [msg] => xyx 
                       [social] =>xxx 
                       [priority] => 1 ) 
        [1] => Array ( [msg] => vvv 
                       [social] => 
                       [priority] => 2 ) 
        [2] => Array ( [msg] => hhh 
                       [social] => 
                       [priority] => 2 ) 
        [3] => Array ( [msg] => rrr 
                       [social] => jws 
                       [priority] => 2 ) 
        [4] => Array ( [msg] => hhhh. 
                       [social] => fff 
                       [priority] => 3 ) 
)

After that suffle() . .

Store the messages in a/the session, display one on each load:

session_start();

if (empty($_SESSION['messages'])) {
    $_SESSION['messages'] = $messages;

    // sort by priority if necessary:
    // usort($_SESSION['messages'], function ($a, $b) { return $a['priority'] - $b['priority']; });
}

$message = array_shift($_SESSION['messages']);
echo $message['msg'];

To rotate the array (feedback to comment):

$messages[] = array_shift($messages);

i have tried it ??? :( .. its not the solution fr MVC and ajax base loading i have also tried to create the session on index page but when the ajes load its clared the session – codeBloger Feb 24 '16 at 16:27
Huh? Why is it not a solution "for MVC", and how does AJAX factor into this? – deceze Feb 24 '16 at 16:28
just give the answer yes or no .. is their any method to shuffle the array sequentially ??? like this 0 1 2 3 4 ---> 1 2 3 4 0 ---> 2 3 4 0 1 – codeBloger Feb 24 '16 at 16:33
That's not "shuffling sequentially", that's called *rotating*. I've added how to do that to the answer. – deceze Feb 24 '16 at 16:35
There's no big difference between rotating the array and doing what I'm suggesting, just that rotating uses more session storage (assuming you'd store that in the session). – deceze Feb 24 '16 at 16:36
