How to generate the six winning numbers to win the Lottery with PHP

The following example shows how to create six random numbers using PHP.

Code:

<style type="text/css">
	div.lottery-panel {
		background-color:#eee;
		border:1px solid #789;
		font-family:Verdana;
		text-align:center;
		width:200px;
	}
	
	span.lottery-panel-title {
		border-bottom:1px solid green;
		color:green;
		font-family:Verdana;
		font-size:14px;
	}
	
	span.lottery-panel-footer {
		color:gray;
		font-size:12px;
	}
	
	table {
		margin:10px auto;
		width:180px;
	}
	
	td {
		background-color: orange;
		border:1px solid #aaa;
		border-radius:14px;
		color:black;
		font-size:16px;
		height:28px;
		text-align:center;
		width:24px;
	}
</style>

<div class="lottery-panel">
<span class="lottery-panel-title">Here's your lucky numbers!</span>
<table border='0'>
	<tr>
	<?php
	// Declare an array of numbers
	$numbers = array();
					
	for($n=0;$n<6;) {
		// Generate a random number
		$r = rand (1, 90);
		
		// Checking if the number is not in the array
		if(!in_array( $r, $numbers) )  :
			$numbers[$n] = $r;
			$n++;
		endif;
	}
		
	// Order the array in ascending order
	sort($numbers);
	
	// Print the numbers drawn
	for($n=0;$n<6;$n++) {
		if($numbers[$n] == 0)
			echo("<td>?</td>");	
		else
			echo("<td>" . $numbers[$n] . "</td>");
	}
	?>
	</tr>
</table>
<span class="lottery-panel-footer">Good luck ;-)</span>
</div>

This example is useful to understand some PHP functions:

• - Use arrays

• - Generate random numbers within a range

• - Check if a number is present in the array

• - Sort an array

We do not guarantee that you will win the Lottery with this example, but at least you learned something about PHP.
