<?php $mix = array("Cars"=> array("Alto","Scooty"),"Fruit"=>array("orange","Mango")); foreach ($mix as $s){ echo "$s"; }

Question

Where is my error

Answer 1

When you run this code, you get :
in log : PHP Notice: Array to string conversion
and the output is : ArrayArray
The problem is that $s contains again array.

It depends what you want to achieve.
You can use var_dump($mix) or print_r($mix) to see the content of the array with additional info or if you just want to print the content of the inner arrays, you can use another loop. For example:

foreach ($mix as $s){
foreach($s as $x) {
echo("$x ");
}
echo("<br/>");
}
