    PHP Tutorials

    In this three-part tutorial, I show how we can include other files, explode text into chunks which are put into an array which we can search through. I chose to use a practical example and use a list of food items.

    Here are the sources used in this tutorial:
    food.php
    <?php
//Food list

$food = array();
$food[] = array(1, array("egg","eggs"));

$food[] = array(6, array("gallons of milk","gallon of milk"));

$food[] = array(4, array("loaf of bread","loaves of bread"));

$food[] = array(2, array("tacos","taco"));

$food[] = array(0.5, array("water bottle","water bottles"));

$food[] = array(2, array("cup of flour","cups of flour"));

?>
    tut014.php
    <?php
//PHP Tutorial 014
include("food.php");
?>
<form method="post" action="?">

Please put in your list of items, like 1 egg, 2 eggs, and seperate them by commas(&quot;,&quot;).
<br />
<input type="text" name="list" size="100" />

<input type="submit" value="create list for printing" />
</form>
<?php
if(isset($_REQUEST['list'])){

	$list = explode(",",trim(stripslashes($_REQUEST['list'])));

	$count = count($list);
	for($x=0; $x< $count; $x++){

		$list[$x]= explode(" ",trim($list[$x]), 2);

	}
	$list2 = array();
	$foodcount = count($food);

	for($x=0; $x< $count; $x++){

		for($y=0; $y< $foodcount; $y++){

			if(in_array($list[$x][1],$food[$y][1])){

				$list2[] = array($list[$x][1], $food[$y][0], $list[$x][0]);

			}
		}
	}

	?>
	<table width="300"><tr><th>Item Name</th><th>Unit Price</th> <th>Quantity desired</th></tr>

	<?php
		$newcount = count($list2);
		$total = 0;

		for($x=0; $x< $newcount; $x++){

			echo "<tr><td>".$list2[$x][0]."</td><td align=\"center\">". $list2[$x][1]."</td><td align=\"center\">". $list2[$x][2].'</td></tr>'."\n";

			$total += (real)$list2[$x][1]*(real)$list2[$x][2];

		}
	?>
	<th>Total is: </th><th>$<?php echo $total; ?></th><th>&nbsp;</th>

	</table>
	<?php
}
?>
