I don't believe you 'push' to an associative array like this, but if you want to add black for example...just do: $colors['black'] = '#ff'; -Brad Jonas Rosling wrote: Need solve another case regarding array maps.

Re: [PHP] array_push in array maps
There's allways mutch to learn. :-) I'm very happy for all help I can get. I ran into another problem when trying to insert a value. I had no problem with: $test['something'] = '2500'; But when I want to have a value from a special column i a row the followint doesn't work: $test[$row[2]] = $row[5]; Or: $test[$row(2)] = $row[5]; Do I need to do some kind of concatenating?

Re: [PHP] array_push in array maps
Jonas - what do you mean 'it doesn't work' (it's like me saying 'the ATM doesn't work and forgetting to mention I'm trying to withdraw 10,000,000 disney dollars - when I mention that fact the reason is probably obvious to you why it doesn't work) Brad Bonkoski wrote: What kind of values are stored in $row[2] and $row[5]? You might need to keep the single quotes $test['$row[2]'] = $row[5]; no this is wrong, unless you want the array key in this case to be the *exact* *literal* string '$row[2]' - which is unlikely. Jonas do the following (in the relevant place in your code) and see what is in $row: var_dump($row); -Brad Jonas Rosling wrote: There's allways mutch to learn. :-) I'm very happy for all help I can get.

Ah, Lasso! I coded that in my previous job. Left it to commit to the
world of PHP, but I saw lots of potential in Lasso 8 (we were in
3/4/5). Sort of miss it sometimes...*sniff*
Anyway, all of the comments are in the right direction. A couple
things to fill in the gaps:
PHP Arrays are indeed a mash-up like Jochem said. If you want to
get at an array element using a numerical key, then simply use the
number without any quotes, like so:
echo $array[2];
However if you want to get at an array element using a string key,
then it must be surrounded in quotes (single or double, but see below
for more):
echo $array['my_key'];
Now, single quotes and double quotes are slightly (and also very)
different in PHP. Read the manual for the details
(http://uk.php.net/manual/en/language.types.string.php), but one thing
to know is that the $ sign is a literal $ sign when it is in a string
surrounded by single quotes; but surround it with double quotes, and
it will help you create a variable (assuming you follow it with legal
variable naming characters).
So if you have a variable:
$lang = 'Lasso';
And try to print it in a string with single quotes, it won't work:
echo 'I used to program in $lang'; // this prints 'I used to program in $lang'
But around double quotes, all is well:
echo I used to program in $lang; // this prints 'I used to program in Lasso'
And if you have a complex variable within a string and you want to
help PHP figure out what's a variable and what's not, use { } to
frame the variable name:
echo Look at my class {$my_class-get('name')} and my array
{$my_array['key']} !;
Make sense? The manual explains a lot more, so be sure to read up.
Also, unless Lasso changed in 8+, there's one other thing to remember
about arrays. In PHP, arrays will keep their order of elements as you
have created it. IIRC, Lasso never guaranteed this, so you always had
to take extra measure to build your arrays such that you could iterate
through them in a reliable fashion. No worries in PHP, the order
sticks (and you can of course re-order it).
HTH, Good luck,
John W
