Re: [PHP] postgresql array with PHP

Hello All,

I have a few array types in a table that I'd like to update/retrieve from
PHP. I manage to update/insert the array with a common sql statement but
am having a tough time retrieving the data back into an array like
form. PHP seems to store the result of a Postgresql array as a single
element. Is there a simple way to retrieve Postgresql array datatypes as
a PHP array instead of a single element?

Thanks,

Steve Bourg

I had the same problem.

I believe having an array field type in a database table doesn't help keep
atomicity of the database.

What I did was, thought about my table schema a little more. Worked out
that I can use the array field type for only storing numbers. Why?

When I receive the row from postgres I explode it. If I was using text in
the array, it may contain "," which would then ruin the explode.

Where $row[6] is the selected array field containing only numbers.

$new_array = explode(",", ereg_replace("[{-}]", "", $row[6]));

I was talking to rasmus ages back and he said there is no support for
arrays from postgresql.

Wunner why in the origional design of PostgreSQL that an array function
was not considered? Any Clue?
