数组操作的想法

Question

I have two arrays.

$Array1 = array("Maza", "Nissan","Tacoma","Cobalt","Explorer");

and second array is

array(
    (int) 0 => array(
        (int) 0 => 'In Stock',
        (int) 1 => 'Cars'
    ),
    (int) 1 => array(
        (int) 0 => 'In stock',
        (int) 1 => 'Cars/Toyota/Tacoma'
    ),
    (int) 2 => array(
        (int) 0 => 'Out of Stock',
        (int) 1 => 'Cars/Toyota/Celica'
    ),
    (int) 3 => array(
        (int) 0 => 'In Stock',
        (int) 1 => 'Cars/Ford/Fusion'
    ),
    (int) 4 => array(
        (int) 0 => 'Out of Stock',
        (int) 1 => 'Cars/Ford/Explorer'
    ),
    (int) 5 => array(
        (int) 0 => 'In Stock',
        (int) 1 => 'Cars/Chevy/Cobalt'
    ),
    (int) 6 => array(
        (int) 0 => 'In Stock',
        (int) 1 => 'Cars/Nissan'
    )

)

Now I want to see what cars in stock or not based on the first and second array. So for Cobalt, it will return me In Stock, where as for Explorer, it will return me out of stock. And for Mazda it can retun "Do not carry" Where I am confused is wheher or not to explode the array[1] by slash"/" and then lookinto it. Is there another easier/faster way to do it. thanks

Try this:

$cars = array("Maza", "Nissan","Tacoma","Cobalt","Explorer");
$stocks=array(
    (int) 0 => array(
        (int) 0 => 'In Stock',
        (int) 1 => 'Cars'
    ),
    (int) 1 => array(
        (int) 0 => 'In stock',
        (int) 1 => 'Cars/Toyota/Tacoma'
    ),
    (int) 2 => array(
        (int) 0 => 'Out of Stock',
        (int) 1 => 'Cars/Toyota/Celica'
    ),
    (int) 3 => array(
        (int) 0 => 'In Stock',
        (int) 1 => 'Cars/Ford/Fusion'
    ),
    (int) 4 => array(
        (int) 0 => 'Out of Stock',
        (int) 1 => 'Cars/Ford/Explorer'
    ),
    (int) 5 => array(
        (int) 0 => 'In Stock',
        (int) 1 => 'Cars/Chevy/Cobalt'
    ),
    (int) 6 => array(
        (int) 0 => 'In Stock',
        (int) 1 => 'Cars/Nissan'
    )

);
$output=array();
foreach ($cars as $car) {
   foreach ($stocks as $stock) {
    if(in_array($car, explode('/', $stock[1]))){
        $output[$car]=$stock[0]; 
        break;
        }else{$output[$car]='Do not care';}
} 
}
echo '<pre>';
print_r($output);

This will print:

Array
(
    [Maza] => Do not care
    [Nissan] => In Stock
    [Tacoma] => In stock
    [Cobalt] => In Stock
    [Explorer] => Out of Stock
)
