Crucial Array Question!

marcobr

Hi!

I have an array with some repeated keys and i need to print that as it is without override values like php does.

// Example

$my_array = array('year' => '1974', 'car' => 'monza', 'car' => 'fusca', 'owner' => 'Giba');

foreach($my_array as $key => $val){
    echo $key'. => .'$val.'<br>';
}

// actually prints:  

//year => 1974 
//car => fusca
//owner => Giba


// i would like:

//year => 1974
//car => monza
//car => fusca
//owner => Giba

I had dreaming about some function with an specified parameter to do it easily, e.g. :rolleyes:

function loop_array($arr, $override = FALSE){

// if TRUE no override values else overrride ...  

}

Maybe do you know a trick or bypath to do it.

Kindest Regards,

BTW:.

Please, don't ask me why i need it ... just tell me if is possible to accomplish it! And sorry 4 my poor english. :p

Ummm I don't think you can have duplicate keys in an array?

The second time you set the 'car' key, it overwrites the first one.

Perhaps instead you should have 'car' be an array of cars. Or you could have car1, car2, car3 etc if you had a finite amount of cars to represent.

I would use a multidimensional array so you would have

$my_array[$carname][year] = 1924;
$my_array[$carname][owner] = "Giba";

Then you would just use nested foreach loops to get the variables out.

something like

foreach ($my_array as $key=>$value)
{
    foreach ($my_array[$key] as $key2 =>$value2)
    {
        print "car $key has a $key2 of $value2";
    }
}

Really a trick. 🆒

Thanks jamie_kerwick !
