This is actually documented under array_merge() (was it always? -
dunno) but omits to mention that shared keys will be overwritten on a
first-come first-served basis. Quick update, anyone with access?

We know, but it needs to be documented nevertheless. I posted a rather
detailed test. The question is "where" to document it exactly.

$array1 + $array2 is *not* the same as array_merge(). See for yourself
with array(1, 2) and array(5, 6, 7).

Where should this feature be documented, I see two viable options:

a) Under array_merge()
b) A new "Array Operators" man page.

I assume most people wanting to merge arrays will go to array_merge()
but having it's own man page could make room to clearly explain the
differences of it and array_merge and array_merge_recursive. I vote
for (b). Of course the functions would link to it. This is kinda like
how `backticks` are documented now, as, "Execution Operators".

A brief note under "Arithmetic Operators" may be appropriate too.

Also, for those interested in documenting this beast, please see this

The behaviour of the following code doens't seem to be documented:

<?
    $foo = array(27 => 'Ene');
    $bar = array(-1 => 'Mene');
    
    $baz = $foo + $bar;

    var_dump($baz);
?>

array(2) {
  [27]=>
  string(3) "Ene"
  [-1]=>
  string(4) "Mene"
}
