如何在多维数组中获取一个特定条目

Question

this is the print_r of my array

    Array ( 
    [0] => Array ( [displayorder] => 3 [menuname] => Accounting Module [menuurl] => [menuflag] => 1 [menuid] => 3 ) 
    [1] => Array ( [displayorder] => 4 [menuname] => My Profile [menuurl] => myprofile.php [menuflag] => 0 [menuid] => 4 ) 
    [2] => Array ( [displayorder] => 6 [menuname] => HR Module [menuurl] => [menuflag] => 1 [menuid] => 2 ) 
    [3] => Array ( [displayorder] => 9 [menuname] => Administrator [menuurl] => [menuflag] => 1 [menuid] => 1 ) )

I want to make a condition that when i have a menuid input it will get the menuname of the array of the menuid

found this solution:

$myarray[0]['menuname']; from here

but it only gets the menuname of the first array how can you make it dynamic?

Answer 1

create a function passing your multi array and menu id as parameter to it, to return desired value from your multi-array, like:

function getMenuNameById($yourArr, $menuId) {
    foreach($yourArr as $val) {
        if( $val["menuid"] == $menuId ) {
            return $val["menuname"];
        }
    }
}
//use it
$menuName = getMenuNameById($your_multi_arr, $menu_id);
