Got it, thanks a lot. One hint - maybe someone should add to manual,
what is key and what is it not....

Key Key Key
This is what he means, ap is NOT a KEY in the first array it is a
VALUE.
The function you want is in_array() -

for [EMAIL PROTECTED]: Can you explain me your words:
Simple because 'ap' is NOT a key in the first case.
?????
Just don't know, what you mean...

first case:
array(3) { [1]=> string(2) "ap" [2]=> string(2) "aa" [3]=> string(2)
"dd" }
second case:
array(3) { ["ap"]=> int(1) ["aa"]=> int(2) ["dd"]=> int(3) }
Why is this different? Shouldn't this be the same?
as Array() definition says:
Syntax "index => values", separated by commas, define index and values.
index may be of type string or numeric. When index is omitted, a
integer index is automatically generated, starting at 0. If index is an
integer, next generated index will be the biggest integer index + 1.
Note that when two identical index are defined, the last overwrite the
first.
So I have used in first case the Example 3. 1-based index with
array():
$firstquarter = array(1 => 'January', 'February', 'March');
I thing, that the second case definition is wrong and should return
error, but as I see, the function array_key_exists works with this...
I'm I mad or what???

Simple because 'ap' is NOT a key in the first case. See yourself with
var_dump($pole); how the array looks like.

Hello,
I'm trying function array_key_exists in this sample script, but doesn't
work:
<?
$a="ap";
$pole = array(1 => "ap", "aa", "dd");
if (array_key_exists($a, $pole)):
echo "The element is in the array";
endif;
?>
but when using:
$pole = array("ap" => 1, "aa" => 2, "dd" => 3);
it's working. Can somebody look at this problem?
Thanks,
Pavel Hrabal
