Thread: postgresql array with PHP

postgresql array with PHP

From
Date:
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.

TIP 2: you can get off all lists at once with the unregister command
    (send "unregister YourEmailAddressHere" to majordomo@postgresql.org)
