Unit 7: Multidimensional Arrays

Number => 25, Notes
),
array( Title => “orchid”,
Price => 1.15,
Number => 7

)
);
?>
It is easier to work with this array, in case you need to get a single value out of it. Necessary
data can be easily found, if you turn to a proper cell using meaningful row and column names
that bear logical content. However, we are loosing the possibility to use simple for loop to view
all columns consecutively.
You can view outer numerically indexed $shop array using for loop. Each row of the $shop
array is an associative array. Hence, inside the for loop you need for each loop. Also you can
get each element from associative array manually:

<?php
echo “<h1>Manual access to each element from associative array</h1>”;

for ($row = 0; $row < 3; $row++)
{
echo $shop[$row][“Title”].” costs “.$shop[$row][“Price”].” and you get “.$shop[$row]
[“Number”];

echo “<br />”;
}
echo “<h1>Using foreach loop to display elements</h1>”;
echo “<ol>”;
for ($row = 0; $row < 3; $row++)
{
echo “<li><b>The row number $row</b>”;

echo “<ul>”;
foreach($shop[$row] as $key => $value)
{
echo “<li>”.$value.”</li>”;
}
echo “</ul>”;
echo “</li>”;
}

echo “</ol>”;
?>
