I sent this to the general list, but I didn't get definitive answer.
Maybe internals is the better forum to talk about it.
If you have a test code, or other pointers towards a definitive answer,
I'd love to try it.
Thanks
Php experts everywhere,
I want to merge two arrays, and I want to store the result as the first
array. Something like the following:
$array1 = array_merge ($array1, $array2);
So far the code gives me what I want. However, suppose if $array1 is
extremely huge, am I introducing a bug here because of possible race
condition? It's possible that array_merge has two write something to
$array1 (left hand side) before it even finishes reading it (argument)
in the first place. Let alone merging the two.
Should I just go conservative and do:
$tmp = array_merge($array1, $array2);
$array1 = $tmp;
Thank you,
Ezra
