Question

Lets say I have

<?php 

$type[ford][focus] = 'some text';
$type[ford][fiesta] = 'some text';

$type[toyota][corola] = 'some text';
$type[toyota][avensis] = 'some text';

$type[bmw][x6] = 'some text';
$type[bmw][x5] = 'some text';

$type[audi][a6] = 'some text';
$type[audi][a8] = 'some text';



function show($car){

foreach ($car as $model)
{
echo $model;
}

}



echo 'Best cars';
show ( $type[bmw] );

echo 'Other cars';
show ( $type[ford] );


?>

What I need is that the rest of cars that are not used (audi and toyota) to be displayed in the last function. So show ( $type[ford] ) should display ford, audi and toyota cars.

Thank you in advance.

I’m making a copy of the original variable here, but you can modify the original too if it’s not used anymore after this.

$cars = $type;

echo 'Best cars';
show ( $type[ 'bmw' ] );
unset( $cars[ 'bmw' ] );

echo 'Other cars';
foreach( $cars as $car ) {
    show( $car );
}
