Question

I have a javascript client passing a parameter to a server function (I’m using ExtJS Direct). Sometimes the client sends a single object, sometimes it sends an array of objects.

Currently I’m using this EnsureArray function to ensure the parameter is an array, and then I do foreach:

// Wraps a non array variable with an array.
function EnsureArray( &$aVar )
{
    if ( !is_array( $aVar ) )
        $var = array( $aVar );
}

function Destroy( $aRecords )
{
    // $aRecords might be a single object or an array of objects. Ensure it's wrapped as an array.        
    $this->EnsureArray( $aRecords );

    foreach ( $aRecords as $aRecord )
    {
        sql( "UPDATE Groups SET deleted = true WHERE id = $aRecord->id LIMIT 1" );
    }        

    return array(
        'success' => true,
    );
}   

Is there a trick, neater way, one line that can do the same?

Edit: Since posting this question, I’ve found that ExtJS has an option to send all records wrapped in array.

You could try the following, instead of the function:

$aRecords = is_array($aRecords) ? $aRecords : array($aRecords);
