PHP add an array inside an array

问题

I am creating an array like so:

foreach($communitiesArray as $row => $value)
{
        $newArray[]['Project'] = $value; 
}

which gives me this:

[0] => Array
        (
            [Project] => Array
                (
                    [ExternalProjectID] => 53
                    [ProjectName] => Doon Creek
                    [Address] => 123 Fake St
                    [City] => Toronto
                    [Province] => ON
                    [Latitude] => 43.0000
                    [Longitude] =>  -80.0000
                    [Website] => http://www.website.com/our-communities.php?newcommunity=53
                    [ContactPhone] => 555-5555
                    [ContactEmail] => email@email.com
                    [SalesOfficeAddress] => 123 Fake St
                    [SalesOfficeCity] => Toronto
                    [SalesOfficeProvince] => ON
                )

        )

What I am trying to do inside this array is create another array called Location and have the Address, City, Province, Latitude and Longitude inside this array called Location which will be inside the Project array. How would accomplish this?

UPDATE

I tried the following:

foreach($communitiesArray as $row => $value) {
        $newArray[]['Project'] = $value;
        $newArray[]['Project']['Location'] = array (
    'Address'   => $Address,
    'City'      => $City,
    'Province'  => $Province,
    'Latitude'  => $Latitude,
    'Longitude' => $Longitude
);
}


[0] => Array
            (
                [Project] => Array
                    (
                        [ExternalProjectID] => 53
                        [ProjectName] => Doon Creek
                        [Address] => 123 Fake St
                        [City] => Toronto
                        [Province] => ON
                        [Latitude] => 43.0000
                        [Longitude] =>  -80.0000
                        [Website] => http://www.website.com/our-communities.php?newcommunity=53
                        [ContactPhone] => 555-5555
                        [ContactEmail] => email@email.com
                        [SalesOfficeAddress] => 123 Fake St
                        [SalesOfficeCity] => Toronto
                        [SalesOfficeProvince] => ON
                    )

            )
[1] => Array
        (
            [Project] => Array
                (
                    [Location] => Array
                        (
                            [Address] => 
                            [City] => 
                            [Province] => 
                            [Latitude] => 
                            [Longitude] => 
                        )

                )

        )

Assuming that your original $value contains the array itself you can do the following:

$locationKeys = array('Address', 'City', 'Province', 'Latitude', 'Longitude');
$newArray = array();

//going over all the projects
foreach($communitiesArray as $projects) {

    $project = array('Location' => array());

    //Going over the keys and values of the current project
    foreach($projects as $key => $value) {
        //if the current key is the location info, we put it under Location
        if(in_array($key, $locationKeys)) {
            $project['Location'][$key] = $value;
        } else {
            $project[$key] = $value;
        }
    }

    $newArray[] = $project;
}

If I am understanding you correctly, you are wanting a location element under the project element in your array. And this location element is also an associative array that will hold address, city, etc. If this is correct, you can instantiate it like this:

$newArray[]['Project']['Location'] = array (
    'Address'   => $Address,
    'City'      => $City,
    'Province'  => $Province,
    'Latitude'  => $Latitude,
    'Longitude' => $Longitude
);

This should works

foreach($communitiesArray as $row => $value)
    { 
            if($row == 'Address'){
               $newArray[]['Project']['Location']['Address'] = $value; 
            }elseif($row=="City"){
               $newArray[]['Project']['Location']['City'] = $value; 
            }
            elseif($row=="Province"){
               $newArray[]['Project']['Location']['Province'] = $value; 
            }
            elseif($row=="Latitude"){
               $newArray[]['Project']['Location']['Latitude'] = $value; 
            }
            elseif($row=="Longitude"){
               $newArray[]['Project']['Location']['Longitude'] = $value; 
            }else{
               $newArray[]['Project'] = $value; 
            }
    }

You will need to check each occurance in the $value array so you can decide what you want to do with each entry in that array.

Simply build 2 new temporary arrays, and at the end put them together and add them to your $newArray

foreach($communitiesArray as $row => $value) {

    $t1 = array();
    $t2 = array();

    foreach ( $value as $name => $val ) {

        switch ($name) {
            case 'Address':
            case 'City':
            case 'Province':
            case 'Latitude':
            case 'Longitude':
                $t1[$name] = $value;
                break;
            default:
                $t2[$name] = $value;
        }
        $t2['Location'] = $t1;
        $newArray[]['Project'] = $t2;
}

回答5:

// List of keys for new Location 
$keys = array_flip(['Address', 'City', 'Province', 'Latitude', 'Latitude',    'Longitude']);

$newArray[] = array_merge (
       //  Those not in list
       array_diff_key($communitiesArray[0]['Project'], $keys),
       // And those in list
       array('Location' => array_intersect_key($communitiesArray[0]['Project'], $keys)));
