Q1: not sure what you're meaning.

Q2: this is a shorthand for an if statement. and since people tend to get confused by it, I would even say it is a BAD shorthand. Translated to regular syntax it reads:

if ($rowclass=="row1") {
    $rowclass = "row2";
} else {
    $rowclass = "row1";
}

and this would reverse the value of $rowclass...

Q1: first of all I recommend reading up on arrays: manual - arrays

then do some experimenting with arrays too. they are important.

$admin is an array. you get an element like this

$a = $admin['elementkey'];

$row also is an array - even an array containing arrays as its elements.

so $row['constant'] is the array 'constant' within the array $row. and an element of that array 'constant' called 'title' can be accessed like this:

$value = $row['constant']['title'];

is same as

$array = $row['constant'];
$value = $array['title'];

and finally using that on $admin:

$a = $admin[$value];

would render the same as the integrated version:

$a = $admin[$row['constant']['title'];

Q2:

It is as I say. I don't know about that code (and I don't need to) This is an if statement doing exactly what I described.
