Unset your PHP references!
foreach ($infs as &$inf) {
…
}
…
foreach($infs as $i => $inf) {
…
}
What’s wrong with the above code? Why after the second loop are there duplicate entries in my $infs array when I did no such thing?
The reason is because I reused the reference variable $inf. That’s a big no-no. To be safe, always unset reference variables when you’re done with them, like this:
foreach ($infs as &$inf) {
…
}
unset($inf);
