I'm trying to figure out how am I supposed to write this snippet
properly:
if (($index = array_search($search, array_keys($pages))) !== false) {
echo "index: $index\n";
} else {
echo "Not found\n";
}
When I search for something that I know exists, it returns the $index
just fine. However, when I search for something that does not exist, it
never tells me 'Not found', instead it just displays a blank index (it
looks like $index = "", not false). Should I be checking it against
'false', or against "" ?
Using PHP 4.0.7-dev.
