        [project_planned_hour] => 500
        [module_name] => Design
        [project_module_time] => 150
        [allocated_time] => 50
    )

[1] => Array
    (
        [employee_id] => 2
        [project_name] => WeeFavR
        [project_planned_hour] => 500
        [module_name] => Coding
        [project_module_time] => 250
        [allocated_time] => 200
    )

    (
        [employee_id] => 2
        [project_name] => WeeFavR
        [project_planned_hour] => 500
        [module_name] => Testing
        [project_module_time] => 100
        [allocated_time] => 50
    )

[3] => Array
    (
        [employee_id] => 2
        [project_name] => Online License
        [project_planned_hour] => 600

Looks like what you want to do is actually run through your array and group it according to project.

This is easy enough if you set up an associated array that lets you lookup your projects.

$grouped_data   = array();
foreach ($data as $item) {
    //we'll used the project name as the key
    $key        = $item['project_name'];
    if (empty($grouped_data[$key])) {
        //this project isn't created yet, create it
        $grouped_data[$key]         = $item;
        $grouped_data[$key]['modules']  = array(); //create the module sub array to store things
    }
    $grouped_data[$key]['modules'][]        = $item; //store your module for this project 
}

Of course you'll need to do some work of your own to clean up what you store in the sub array. Currently it stores everything so some keys are duplicated. But this should get you started without a problem.

JohnP Over a year ago

Not sure how they don't match up, so I can't really help you anymore unless you give me more information.

Update your question with what you tried, and how it is differing from what you are expecting.

Just like you could save a variable inside an array, you also can save an array inside an array:

$someArray = array(
    'Value 1',
    array(
        array(
            'Some more value,
            'more'
        ),
        array(
            'Some more value,
            'more'
        )
    )
);

Make sure you will have some index for your modules

$myArray = Array();    

$myArray[0] = Array(    
    "employee_id" => 2,    
    "project_name" => "WeeFavR",    
    "project_planned_hour" => 500,    
    "modules" => Array(    
        Array(    
            "module_name" => "Design",    
            "project_module_time" => 150,    
            "allocated_time" => 50    
        ),    
    ),    
);

What you can do is something like this:

    $arr_project = array ();
    $arr_example_tmp =  array ("module_name" => "Design",
                        "project_module_time" => 200,
                        "allocated_time" => 100);


    $arr_project["project_planned_hour"][] = $arr_example_tmp;


    $arr_example_tmp =  array ("module_name" => "Coding",
                        "project_module_time" => 200,
                        "allocated_time" => 100);

   $arr_project["project_planned_hour"][] = $arr_example_tmp;

what isn't? I did a little edit because I missed some quotes. When I var_dump($arr_project) it's a filled array

$out = array();
foreach ($arr as $key => $value){
    $dex = $value['employee_id'].' - '.$value['project_name'];
    if ( ! isset($out[$dex])){
        $out[$dex] = array_slice($value, 0, 3);
    }
    $out[$dex]['details'][] = array_slice($value, 3);
}
$out = array_values($out);
print_r($out);
