Intermittently invalid operator.

[tuppence]

$form += @mysql_fetch_array($result); //populate the array $form

This line is intended to add the contents of a child table to the array $form already populated from the parent. It is not possible, or I am not crafty enough, to construct the SQL which will read the tables together.

Most times this section of code executes normally. Sometimes, it is reported as containing an invalid operator.

Please explain what is wrong and what I should do about it.

Thank you in advance.

What is it supposed to do? I've never seen anyone trying to use '+' to "add arrays" before (whatever that means). I can't even see how it's supposed to "execute normally".

I can think of at least three ways to "add the contents of an array" for various values of "add", but without a clearer idea of what's going on:

If $form is an array that is supposed to contain all the records being returned (and the line in question is in a loop), then $form[] = mysql_fetch_array($result); is appropriate.

If the new array is to be merged (so that $form['field'] is equal to mysql_fetch_array($result)['field'] (and I know that's invalid syntax), when $form already contains some other stuff of its own, $form = array_merge($form,mysql_fetch_array($result)) has that effect.

If there's some numeric field in $form to which the contents of some field in the fetched array, then the field would need to be specified.
