now we will use nested foreach loop to display the data from the given two multidimensional array.See Example

<?php$students = ['student1' => ['name' => 'Rahul', 'age'=>21, 'class'=> 9],'student2' => ['name' => 'Gargi', 'age'=>25, 'class'=> 10],'student3' => ['name' => 'Jyoti', 'age'=>19, 'class'=> 12],];foreach($students as $key => $student){echo 'data of '.$key.'<br>';/*here $student is an array */foreach($student as $key2 => $value){echo $key2.' : '.$value.'<br>';}}?>

Output

data of student1name : Rahulage : 21class : 9data of student2name : Gargiage : 25class : 10data of student3name : Jyotiage : 19class : 12

So in this way we do traversal using Multidimensional Array foreach loop in PHP, although it is not necessary that you use foreach loop only, you can also use for loop.

PHP Traversing Multidimensional Array Using for loop

To traverse through a for loop, we will take the example of Two Multidimensional Indexed Array, although you can also traversal the Associative Array through a foreach loop but then we have to extract the array keys.Example-

<?php$students = [['Rahul',25,9],['Gargi',28,10],['Jyoti',19,12],];$size = count($students);for($s=0; $s<$size; $s++){ echo 'data of studnet'.($s+1).'<br>';/*now get inner array size */$in_size = count($students[$s]);for($i=0; $i<$in_size; $i++){echo $students[$s][$i].'<br>';}}?>

Output

data of studnet1Rahul259data of studnet2Gargi2810data of studnet3Jyoti1912
