$row[ ] = $row_assoc[$variable] -- huh?

[Anon]

I'm working through SAMS learn PHP in 24 hours. One bit has me stumped, & it has to do with a bit of code they have in the Chapter on Objects that uses array_push with an associative array.

I can't picture what's going on =(

Here's the code, which I've taken from an object def'n:

function addRowAssocArray ($row_assoc)
{
$row = array ( );
foreach ( $ this->headers as $header)//header was defined in the class as an array variable
{
if (! isset ($row_assoc[$header] ) )
$row_assoc[$header] = " ";

the following is what I don't get

$row[ ] = $row_assoc[$header]; // Can't figure out what this looks like using #'s

}
array_push($this->table_array, $row);
return true;
}

If anyone could shed a bit of light, I'd much appreciate it.

$row[] - adds an item to the array. So if you have an array that looks like this:

$row[0] = "Title";
$row[1] = "Name";

And you do this:

$row[] = "Desc";

Your array will now have a new row:

$row[3] = "Desc";

Thanks, although I guess I should have clarified that it's the fact that it's being added to an associative array that I don't get.

So, the addRowAssocArray function in the class is called:

$test->addRowAssocArray( array ( b=>0, a=>6, c=>3) );

and what I don't get is how an associative array is added by

$row[ ] = $row_assoc[$header];

Does the $header variable replace anything, does it become a multi-dimensional array?

Sorry, should have been more clear the first time!

There's nothing associative about it.

The function just creates an ordinary array ($row) of whatever there is in array $row_assoc, at the indexes it finds in the array $this->headers.
