I can see what u are saying. Its all about the ===
Anyhow.. this thing does not work in a loop. I guess this is my prob. There
might be something wrong with the boolean. I tryed it with different
settings, but still wrong:
Here is what I mean:
$fruit = array('apple','banana','cranberry');
$findme = array('apple', 'notlisted');
foreach($findme AS $value){
if (($key = array_search($value, $fruit)) !== false) {
print "Key ($key) was found from value $value<br>";
} else {
print "Sorry, $value was not found in array \$fruit<br>";
}
}
Replys:
Key (0) was found from value apple
Key () was found from value notlisted
So there must be still something wron in th stmt.
Thanx for your help,
Andy
