Looping over multidimensional array using PHP

It requires a little more thinking while working with loops in multidimensional arrays. Let’s see the situation here.

Say we got a two-dimensional array.

<?php

 $students[0]["fname"]="John";
     $students[0]["lname"]="Cena";
     $students[1]["fname"]="Shawn";
     $students[1]["lname"]="Patrick";
     $students[1]["fname"]="John";
     $students[1]["lname"]="doe";
     for($outer=0;$outer<count($students);$outer++):
           foreach($students[$outer] as $key => $value):       
 echo "\$students[$key][$innerkey] = ";
     echo $students[$key][$innerkey]." ";
     echo"<br>"; 
 endforeach;         
     echo"<br>";
     endfor;
  
 // or we can use foreach as outer loop too.

     foreach($students as $key => $innerArray):
           foreach($innerArray as $innerkey => $value):        
           echo "\$students[$outer][$key] = ";
           echo $students[$outer][$key];
           echo"<br>";         
           endforeach;    
           echo"<br>";    
      endforeach;
?>

This will gives output:

$students[0][fname] = John 
$students[0][lname] = Cena 

$students[1][fname] = Shawn 
$students[1][lname] = Patrick 

$students[2][fname] = John 
$students[2][lname] = doe
