Just another quick way to automate the simple process of creating HTML selects with a function. This small function with also remember which value was selected by checking it against the $_POST value and adding a selected="SELECTED" to that option.

2 dimentional array:

$people_array = array(
   '1' => 'Bob',
   '2' => 'James',
   '3' => 'Jessi',
   '4' => 'Sam');

Just call this function either through a request(…) or just simply adding it to the file’s code:

function array2select($array, $post_field){
	foreach($array as $key => $value){
		if($post_field == $key){$selected = ' selected="SELECTED"';}
		echo ''.$value.'';
 		$selected = false;
	}
}

Then just add it where you want the select to do:

< select name="people" >
echo array2select($people_array,$people);
< /select >

This is pretty basic, but it should give you an idea on how arrays and functions can be used together to help speed up projects and automate these basic tasks.
