Good morning, I am doing a virtual store with php without databases and I have a problem. As you can see I have a table with the products. Since there is no database, I have to store this data in a file as an array and I do not know how to do it. I attach code. I also use sessions in this case I'm in session and I mean that aspect does not matter. Thanks

<?php session_start(); ?>

How do I get a Select with PDO in Php correctly How to capture the Primary Key Duplicated error in Android (java) with SQLServer?

You could use the functions json_encode () and json_decode () to work with texts.

It would be something like this:

function guardar_productos($productos){
    $txt = json_encode($productos);    
    $file = fopen('productos.txt', 'w');    
    fwrite($file, $txt);
    fclose($file);    
}

function cargar_productos(){
    $txt = file_get_contents('productos.txt');
    $productos = json_decode($txt);
    return $productos;
}

and call the corresponding function when necessary.

the file would look like this:

{
    "productos": [{
            "id": "1",
            "nombre": "cosa 1",
            "color": "rojo",
            "precio": "10"
        },
        {
            "id": "2",
            "nombre": "cosa 2",
            "color": "azul",
            "precio": "55.7"
        },
        {
            "id": "3",
            "nombre": "cosa 3",
            "color": "",
            "precio": "25"
        }
    ]
}
