Arrays are very important in every programming languages. In this hub you will see another example of php code on the other types of array, the associative and the multidimensional array. You will see the difference between the two and you will learn on how to use them in your coding on a PHP Editor.

Please note that in coding PHP, you must have a PHP editor like notepad++, a php server like apache and much better if you have a database server too like mysql. To have both apache and mysql you might want to download xaamp for free just google it.

To know more about associative and multidimensional arrays, refer to the source code below. You can study and trace the codes and learn how the outputs happen.

Sample PHP Code for Associative Array

<?php
	$student = array("J. Parker" => "ID Number: 00120", "N. Smith"=> "ID Number: 00121", 
	"M. Maclein" => "ID Number: 00122", "A. Garfield" => "ID Number: 00123", "R. Rutherford" => "ID Number: 00124");
	$count = count($student);
	
	echo "<strong>Associative Array Example Output</strong>". "<br/><br/>";
	
	
	echo "Student Name: J. Parker  ".$student['J. Parker']. "<br/>";
	echo "Student Name: N. Smith  ".$student['N. Smith']. "<br/>";
	echo "Student Name: M. Maclein  ".$student['M. Maclein']. "<br/>";
	echo "Studet Name: A. Garfield  ".$student['A. Garfield']. "<br/>";
	echo "Student Name: R. Rutherford ".$student['R. Rutherford']. "<br/>";
	
?>

Sample Output for Associative Array

Sample PHP Code of Multidimensional Array

<?php
	$section = array("Section A" => array("J. Parker", "N. Smith", "M. Maclein"), 
	"Section B" => array("R. Rutherford", "A. Swan", "L. Go"), 
	"Section C" => array("C. Wilson", "N. Tucker", "Z. Page"));
	
	$count = count($section);
	
	echo "<strong>The students on Section A Are: </strong><br />";
	for($i=0; $i<$count; $i++)
	{
		echo $section['Section A'][$i]. "<br />";
	}
	
	echo "<br />";
	echo "<strong>The students on Section B Are: </strong><br />";
	for($i=0; $i<$count; $i++)
	{
		echo $section['Section B'][$i]. "<br />";
	}
	
	echo "<br />";
	echo "<strong>The students on Section C Are: </strong><br />";
	for($i=0; $i<$count; $i++)
	{
		echo $section['Section C'][$i]. "<br />";
	}
?>
