Sorting a multidimensional PHP array chronologically -

this question has answer here:

• how can sort arrays , data in php? 7 answers

i've got multidimensional array stores location , date of gigs looks this

for ($i=0; $i < $numberofgigs ; $i++) {    $gig[$i] = array(     "date" => $date,     "place" => $location   ); } 

i'm getting date , location google calendar api , building table using data, api's response lists events in date added calendar, rather date of event. gives me table looking this.

15/03/2014 - venue 1

30/03/2014 - venue 2

06/04/2014 - venue 3

16/03/2014 - venue 4

i want events in table sorted chronologically, i'm looking way sort $gig array $gig[0] earliest date , $gig[5] latest. i've been looking sorting arrays, i'm having trouble getting head around multidimensional example.

if point me in right direction appreciated!

if have no control how array created, suggest use usort():

$gigs = array(     array('date' => '15/03/2014', 'place' => 'venue 1'),     array('date' => '30/03/2014', 'place' => 'venue 2'),     array('date' => '06/04/2014', 'place' => 'venue 3'),     array('date' => '16/03/2014', 'place' => 'venue 4') );  usort($gigs, 'sortgigs');  print_r($gigs);  function sortgigs($a, $b) {      $datea = date_create_from_format('d/m/y', $a['date']);     $dateb = date_create_from_format('d/m/y', $b['date']);     return date_format($datea, 'u') > date_format($dateb, 'u'); } 

however, if build array yourself, convert date timestamp , use key of array. then, use ksort().

$gigs = array(); ($i=0; $i < $numberofgigs ; $i++) {   $date = date_create_from_format('d/m/y', $date);   $gigs[date_format($date, 'u')] = $location } ksort($gigs); 

loop through gigs:

$content = '<table>'; foreach($gigs $timestamp => $place) {     $content .= '         <tr>             <td>' . date('d.m.y h:i', $timestamp) . '</td>             <td>' . $place . '</td>         </tr>     '; } $content .= '</table>'; print $content;
