Hello experts i have this array from check boxes and i want to echo it by index values i.e. in order of keys like all 0 index values in one pocket and 1 index values in one pocket for example [[0, 0, 0], [1, 1, 1], [2, 2, 2]] with its values like [[1, none, none], [none, 2, 2], [none, none, 3]]
Please can somebody help me ?

$myArray = array(   1 => array( 0 => 1, 1 => "none", 2 => "none"),                   
                    2 => array( 0 => "none", 1 => 2, 2 => "none"),                   
                    5 => array( 0 => "none", 1 => 2, 2 => 3) );  

$newArray = array();
foreach( $myArray AS $masterIndex => $childArray )
{
    foreach( $childArray AS $index => $value )     
    {
        if( !isset($newArray[$index]) )
        {
            $newArray[$index] = array();
        }
        $newArray[$index][] = $value;
    }
}

$outputValues = "["; 

foreach( $newArray AS $childArray ) 
{     
    $outputValues .= "[" . implode(",", $childArray) . "],";
} 
$outputValues = substr($outputValues, 0, strlen($outputValues) -1) . "]";
echo $outputValues;

That is slightly refined version, with ‘implode’ instead of another loop…
