trying to use array_key_exists with 2d array, and failing...

[dumbass]

Hello,

I'm trying to use array_key_exists with 2d array, and failing...I'm trying to check if the interger variable, $action, is in the key of the 2d array $path

I'm trying to do something like this:

if (array_key_exists($action, $path))

but this doesn't seem to do it...

Any help on the syntax would be great, thanks!

Post what code you've got. Try to include as much about $action and $path as possible.

$action is an integer passed in the url, based on what the user selects

$path is a table array which stores info about how to output html blocks, or includes, looks like this:

// content file names
$path[0][0] = 'default';
$path[1][0] = 'who';

// menu colors
$path[0][1] = '#FFFFFF';
$path[1][1] = '#043668';

// sub menus file names
$path[0][2] = 'home';
$path[1][2] = 'who';

I want to use array_key_exists to make sure the interger passed in $action exists in the key of the array $path, but I can't figure out the syntax to do so...

Thanks, d.a.

//hypothetical action
$action = 2;

// content file names
$path[0][0] = 'default';
$path[1][0] = 'who';

// menu colors
$path[0][1] = '#FFFFFF';
$path[1][1] = '#043668';

// sub menus file names
$path[0][2] = 'home';
$path[1][2] = 'who'; 

//this will return false because $path[2] does not exist
array_key_exists($action, $path);

//this will return true because $path[0][2] does exist
array_key_exists($action, $path[0]);

//new action value
$action = 1;

//this will return true because $path[1] does exist
array_key_exists($action, $path);
