Row1
	arr[0][0]	arr[0][1]	arr[0][2]	arr[0][3]

Row2
	arr[1][0]	arr[1][1]	arr[1][2]	arr[1][3]

Row3
	arr[2][0]	arr[2][1]	arr[2][2]	arr[2][3]

 

Example for MultiDimensional Array

Source Code :

<?php

$arr = array(
	   array(1, 2, 3, 4),
	   array(5, 6, 7, 8),
	   array(9, 10, 11, 12)
	   );
echo  $arr[0][0]." ".$arr[0][1]." ".$arr[0][2]." ".$arr[0][3]."<br /> " 
	 .$arr[1][0]." ".$arr[1][1]." ".$arr[1][2]." ".$arr[1][3]."<br /> "
	 .$arr[2][0]." ".$arr[2][1]." ".$arr[2][2]." ".$arr[2][3]."<br /> ";
?>

Output :

1 2 3 4
5 6 7 8
9 10 11 12

Example for MultiDimensional Array using for Loop

Source Code :

<?php
$arr = array(
	   array(1, 2, 3, 4),
	   array(5, 6, 7, 8),
	   array(9, 10, 11, 12)
	   );
	   
for($i=0;$i<3;$i++){
	for($j=0;$j<4;$j++){
		echo $arr[$i][$j]." ";
	}
	echo "<br>";
}
?>

Output :

1 2 3 4 
5 6 7 8 
9 10 11 12 

Example for Multi Dimensional Array using foreach Loop

Source Code :

<?php
$arr = array(
	   array(1, 2, 3, 4),
	   array(5, 6, 7, 8),
	   array(9, 10, 11, 12)
	   );
	   
foreach($arr as $i){
	foreach($i as $j){
		echo $j." ";
	}
	echo "<br>";
}
?>

Output :

1 2 3 4 
5 6 7 8 
9 10 11 12
