When you get the values that you want to show in the keyboard, you need to store these in array. This example was did in Javascript, you must found the equivalent in php code.

If you only have 5 products you don't need a loop, just:

...
{
  'reply_markup': JSON.stringify({
    keyboard: 
    [
      [{'text': 'cat1'},{'text': 'cat2'}],
      [{'text': 'cat3'},{'text': 'cat4'}],
      [{'text': 'cat5'}]
    ],
    one_time_keyboard: true,
    resize_keyboard: true
  })
}
...

If you have undefined products elements you must use a for loop:

var keyboard = [];
var products = ['cat1', 'cat2', 'cat3', 'cat4', 'cat5'];

for (var i = 0; i < products.length; i++) {
  keyboard.push([{'text': products[i]}]);
}

...
{ 
  'reply_markup': JSON.stringify({
    inline_keyboard: keyboard
  })
}
