Accessing Array Values with a variable key

From last few days I have been trying to figure out how to access an array value in PHP using a key value that is stored in a string. So finally i was able to frame a function that could just do that.
Following is the code to get a value from an array with known key
Here
`$arr = Array with values
$key = string with keys seperated with –

function get_array_val($arr,$key)
{
	$e= explode('-',$key);
	$ar = &$arr;
	foreach($e as $v)
		$ar = $ar[$v];
	unset($ar);
	return $arr;

Adding Custom Link to Plugins page in WordPress

I had to search a lot for adding a custom link to WordPress Plugin page that linked to Settings page of my plugin. So here’s a Tutorial on how to add it.

There are two parts of adding Custom Links

Add the following lines to add a filter

add_filter('plugin_action_links',' xydac_settings', 10, 2);

Here xydac_setting refers to the function which is used to add links.

Add the function for handling the Filter

function xydac_settings($links, $file) {
static $this_plugin;
if (!$this_plugin) $this_plugin = plugin_basename(__FILE__);
if ($file == $this_plugin){
$my_link = "<a href="admin.php?page=ultimate-taxonomy-manager">" . __("Settings") . "</a>";
array_unshift($links, $my_link);
}
return $links;
}

Add the links to Settings file of your plugin in this function and assign it to variable $my_link.

Thats all you have to do to add the settings link to your Plugin.
