在php中动态创建多维数组

Question

I am fetching for some values from the database, and i need to dynamicaly create a multidimensional array to look like this:

$found_data = 
array( 
    array('2011-11-02' => 'Mobile'),
    array('2011-11-02' => 'Mobile'),
    array('2011-11-04' => 'Mobile'),
    array('2011-11-08' => 'Desktop'),
    array('2011-11-08' => 'Mobile'),
    array('2011-11-08' => 'Mobile'),
    array('2011-11-08' => 'Mobile'),
    array('2011-11-15' => 'Mobile'),
    array('2011-11-18' => 'Mobile'),
    array('2011-11-21' => 'Desktop'),
    array('2011-11-23' => 'Mobile'),
    array('2011-11-28' => 'Desktop'),
    array('2011-11-30' => 'Mobile')
);

I am thinking something in the lines of:

$found_data = array();

while($last_30_days_fetch = mysql_fetch_assoc($last_30_days_result))
{
    $hit_date = $last_30_days_fetch['hit_date'];
    $hit_device = $last_30_days_fetch['hit_device'];    
    array_push($found_data, array($clean_date=>$hit_device));

}

However the above code, does not work as intended. Any ideas?

// Thanks

Answer 1

$found_data = array();

while($last_30_days_fetch = mysql_fetch_assoc($last_30_days_result))
{
    $found_data[] = array($last_30_days_fetch['hit_date']=>$last_30_days_fetch['hit_device']);
}

why over complicate it or as Dan says put it into a single array there's no need for a multi array unless there's additional data you're not telling us about
