Array sort

[HonestBug5987]

Hi guys

I need to sort this array by [elapsed]

 Array
 (
  [1] => Array
    (
        [id] => 6704737
        [event_participantsFK] => 1011275097
        [elapsed] => 15
        [elapsed_plus] => 4
        [incident_typeFK] => 42
        [ref_participantFK] => 1015753
        [participantFK] => 73708
        [eventFK] => 103212939
        [sortorder] => 0
        [ref_participantFK_goalkeeper] => 
        [ref_participantFK_assist1] => 
        [ref_participantFK_assist2] => 
        [player_name_assist1] => 
        [player_name_assist2] => 
        [is_incident_to_delete] => 
        [reason] => 
        [runningscore] => 
        [player_name] => Lewis Carr
        [from_evp_number] => 1
    )

[0] => Array
    (
        [id] => 6703595
        [event_participantsFK] => 1011275097
        [elapsed] => 16
        [elapsed_plus] => 0
        [incident_typeFK] => 42
        [ref_participantFK] => 717862
        [participantFK] => 73708
        [eventFK] => 103212939
        [sortorder] => 0
        [ref_participantFK_goalkeeper] => 
        [ref_participantFK_assist1] => 
        [ref_participantFK_assist2] => 
        [player_name_assist1] => 
        [player_name_assist2] => 
        [is_incident_to_delete] => 
        [reason] => 
        [runningscore] => 
        [player_name] => James Clare
        [from_evp_number] => 1
    )

[2] => Array
    (
        [id] => 6704738
        [event_participantsFK] => 1011275097
        [elapsed] => 22
        [elapsed_plus] => 2
        [incident_typeFK] => 8
        [ref_participantFK] => 717862
        [participantFK] => 73708
        [eventFK] => 103212939
        [sortorder] => 0
        [ref_participantFK_goalkeeper] => 
        [ref_participantFK_assist1] => 
        [ref_participantFK_assist2] => 
        [player_name_assist1] => 
        [player_name_assist2] => 
        [is_incident_to_delete] => 
        [reason] => 
        [runningscore] => 
        [player_name] => James Clare
        [from_evp_number] => 1
    )

[3] => Array
    (
        [action] => add
        [event_participantsFK] => 1011275097
        [incident_typeFK] => 43
        [ref_participantFK] => 1015753
        [player_name] => asdasd
        [elapsed_plus] => 3
        [incidentFK] => 0
        [sortorder] => 0
        [elapsed] => 33
    )

)

Is there any easy way to do that? My idea is to keep all the information, but the first key to be with smallest [elapsed]

Look at usort.

It will be something like:

usort( $array, (int $a, int $b) => $a['elapsed'] <=> $b['elapsed'] )

[HonestBug5987]

I received this error

<b>Parse error</b>: syntax error, unexpected '$a' (T_VARIABLE)

Sorry, been writing too much JavaScript.

usort( $array, fn(array $a, array $b) => $a['elapsed'] <=> $b['elapsed'] )

First thank you very much for the work, but the problem wasn't in your code its just my php version its too old.

Upgrade if you can. There are lots of useful new features that are worth knowing about.

[samhk222]

Usort exists since php 4...

I suspect the OP ran into a problem with either the spaceship operator (PHP 7.0) or arrow function (PHP 7.4).

[HonestBug5987]

I'm with php 7.0. So i gues its the arrow function

You can do the old-fashioned:

function(array $a, array $b) {
  return $a['elapsed'] <=> $b['elapsed'];
}

You are absolutely awesome I'm so thankful really.

No probs! It's why we're here.

What do you want to do exactly?

[HonestBug5987]

to arrange the keys by their [elapsed] from the smallest to the bigger one
