PHP Taskbook Level 9.7

Make a site that gives a random prediction, good or bad, when you visit it. Predictions should be stored in the DB. When you refresh the page, the prediction should not change during the current day.

Given an arbitrary two-dimensional array:

[
	[11, 12, 13, 14, 15],
	[21, 22, 23, 24, 25],
	[31, 32, 33, 34, 35],
	[41, 42, 43, 44, 45],
	[51, 52, 53, 54, 55],
]

Zero out the elements that are not on the diagonals:

[
	[11,  0,  0,  0, 15],
	[ 0, 22,  0, 24,  0],
	[ 0,  0, 33,  0,  0],
	[ 0, 42,  0, 44,  0],
	[51,  0,  0,  0, 55],
]

Let the file contain the following JSON:

{
	[
		"catg": "catg1",
		"name": "prod1",
		"cost": "100"
	],
	[
		"catg": "catg2",
		"name": "prod2",
		"cost": "200"
	],
	[
		"catg": "catg3",
		"name": "prod3",
		"cost": "300"
	]
}

Generate the following HTML code using the file data and send it to the browser:

<table>
	<tbody>
		<tr>
			<td>1</td>
			<td>catg1</td>
			<td>prod1</td>
			<td>100</td>
		</tr>
		<tr>
			<td>2</td>
			<td>catg2</td>
			<td>prod2</td>
			<td>200</td>
		</tr>
		<tr>
			<td>3</td>
			<td>catg3</td>
			<td>prod3</td>
			<td>300</td>
		</tr>
	</tbody>
</table>
