Checking if a value appears in an array

[thesavior]

So I have this array which contains an array which contains values. I want to check if the value provided is inside the second array.

Here is my structure:

PHP Code:

$array=array(
            "ARRAY2"=>array(
                        "Info",
                        "Board",
                        "License",
                            ),
            "ARRAY3"=>array(
                        "Structure",
                        "Edit",
                        "Add",
                        "Delete",
                        ),
            "ARRAY4"=>array(
                        "View",
                        "Search",
                        "Groups",
                        "Delete",
                        ),
            "ARRAY5"=>array(
                        "Main",
                        "Themes",
                        "Groups",
                        ),            
        ); 


lets say I want to check if Groups is inside ARRAY 4. How would I do that? I know how to check if ARRAY 4 is inside array, but if you go down a level im not exactly sure how to do that.

With 2 minutes of thinking I would do this

PHP Code:

<?php
$array=array( 
            "ARRAY2"=>array( 
                        "Info", 
                        "Board", 
                        "License", 
                            ), 
            "ARRAY3"=>array( 
                        "Structure", 
                        "Edit", 
                        "Add", 
                        "Delete", 
                        ), 
            "ARRAY4"=>array( 
                        "View", 
                        "Search", 
                        "Groups", 
                        "Delete", 
                        ), 
            "ARRAY5"=>array( 
                        "Main", 
                        "Themes", 
                        "Groups", 
                        ),             
        ); 
        
 foreach ($array AS $key => $val_array){
     if(in_array('Groups',$val_array)){
         // do something!
         echo "Found it in array['{$key}']!<br>";
     }
 }
?>

That's for checking all arrays but if you want know which key like ARRAY4 for example, you just have to use this syntax

PHP Code:

in_array("Groups",$array['ARRAY4']);

Heh, thanks, I forgot that you can call array inside an array by $array['ARRAY4']. That solved my problem.

Glad that helped At first I wasn't sure if that would do it hehe

[thesavior]
