                [result] => 65         


        

Answer 1

Use array_merge() to combine the arrays, and then use sort to sort() to sort them, very simple. Would you like an example?

This should sort it for you:

function dateSort($a,$b){
    $dateA = strtotime($a['date']);
    $dateB = strtotime($b['date']);
    return ($dateA-$dateB);
}

$arrayOne = array(
    array(
        'date'      => '2012-01-10',
        'result '   => 65,
        'name'      => 'Les océans'
    ),
    array(
        'date'      => '2012-01-11',
        'result '   => 75,
        'name'      => 'Les mers'
    ),
    array(
        'date'      => '2012-01-13',
        'result '   => 66,
        'name'      => 'Les continents',
        'type'      => 'Scores'
    )
);

$arrayTwo = array(
    array(
        'date'      => '2012-01-12',
        'result '   => 60,
        'name'      => 'Step#1',
        'type'      => 'Summary'
    )
);

// Merge the arrays
$combinedArray = array_merge($arrayOne,$arrayTwo);

// Sort the array using the call back function
usort($combinedArray, 'dateSort');
