How do you navigate a matrix in PHP?

A multidimensional array is an array under an array, like this:

$array = array
 (
 array("brand"=>" Nissan", "stock"=> 15, "sold"=> 12),
 array("brand"=>" Volswagen", "stock"=> 17, "sold"=> 11),
 array("brand"=>" Totota", "stock"=> 8, "sold"=> 6),
 array("brand"=>" Peugeot", "stock"=> 18, "sold"=> 14)
 ); 

This table contains four cars and has two indices: rows and columns. To access or browse all the elements, we need to specify both the row and column indices.

echo $voitures[0][0].": In stock: ".$voitures[0][1].", Sold: ".$voitures[0][2].". 
"; 
Nissan In Stock: 15 Sold: 12

The keyless foreach buckle:

foreach($array as $item) {
 echo $item['brand']." < br>"; print the brand of all cars

 // to find out what's in object
 // var_dump($item); 
}

Runtime:

Nissan
Volswagen
Totota
Peugeot

Using the foreach loop with key:

foreach($array as $i => $item) {
 echo $array[$i]['mark']." In stock: ".$array[$i]['stock']." Sold: ".$array[$i]['sold']." \n"; 

 // $array[$i] is equilent to $item
}

Execution:

Nissan In Stock: 15 Sold: 12
Volswagen In Stock: 17 Sold: 11
Totota In Stock:  8 Sold: 6
Peugeot In Stock: 18 Sold: 14

With for loop:

for($i=0; $i < count($array); $i++) {
 echo $array[$i]['brand']." In stock: ".$array[$i]['stock']." Sold: ".$array[$i]['sold']." \n"; 
}
