count() is not slow, really...
PHP maintains the count internally as you add stuff, so it is a quick
lookup.
Or you could just do:
$Rows[] = array('test'=this is a test);
At least I think that works out the same array-wise...

Hi Folks, Is there a better way of doing the following: $Rows[] = array(); $currentRow = count($Rows) - 1; $Rows[$currentRow]['test'] = this is a test; Specifically I am wonder if I can avoid having to use 'count'.

1) The code above will produce a $currentRow of -1 which is probably not
what you want.
2) If you actually mean that you have an array that contains items and
you want the last one, used end (http://php.net/end).
3) I'm not really sure what the context is, but this is a very odd way
of working with arrays. Either you already know the key or you don't. If
you're just trying to append to the array you can do that with the
following syntax... $Rows[] = array('test' = 'this is a test');

Seems my eyes are to tired today. Didn't read the code very good.
But the answer still stays the same :)
$Rows = array();
array_push($Rows, array('test' = 'this is a test'));

Maybe you didn't notice the [] in the first line of the OP's code?
I think this code should produce 0 for $currentRow, not -1.

Indeed, my bad. In that case the OP is better off creating the item in a
temporary variable and then adding it to the array.
$row = array();
$row['test'] = 'this is a test';
$Rows[] = $row;

what's wrong with skipping the temporary variable and just doing

Nothing, unless you're building a complex element. I was assuming that
the OP had simplified their code down to the minimum required to
illustrate the problem.

Re: [PHP] Array Push question
As you guys can probably guess from the question I'm still getting to
grips with some parts of php.
I had stripped down the code for my original post, maybe this will clear
things up a bit:
$Rows[] = array();
$currentRow = count($Rows) - 1;
$Rows[$currentRow]['test'] = this is a test;
$Rows[$currentRow]['Data'] = array();
$Rows[$currentRow]['Config'] = This is the row config;
So from what you guys have said I have changed it to be the following:
$Rows[] = array('test' = 'this is a test', 'Data' = array(), 'Config'
= 'This is the row config');
Which seems to be doing what I want.
Thanks for the replies,
JC
