RE: [PHP] unset($array[value]) does not work?

[Lazor, Ed]

It is working.

The last two tests you were running weren't actually the same, which was
confusing your testing results.  I've altered the code a little for ease of
testing.  It's included below.

You will see that $unserialized['foo'] still exists! Can anyone explain me
what I'm doing wrong?

 "bar",
"wom" => "bat"
);

echo $array["foo"] . "";
echo $array["wom"] . "";

$serialized = serialize($array);

echo $serialized . "";

$unserialized = unserialize($serialized);

echo $unserialized["foo"] . "";
echo $unserialized["wom"] . "";

echo "";

$keys = array_keys ($unserialized);

echo $keys[0] . "";
echo $keys[1] . "";

echo "";

if (key_exists("foo", $unserialized)) { echo "foo exists!"; }
if (key_exists("wom", $unserialized)) { echo "wom exists!"; }

echo "";
unset ($unserialized['foo']);

if (key_exists("foo", $unserialized)) { echo "foo exists!"; }
if (key_exists("wom", $unserialized)) { echo "wom exists!"; }

?>

[PHP] unset($array[value]) does not work?

[Leon Mergen]

Hello,

I am currently testing out some things with removing elements from arrays,
and I find it strange that the following statement does not work for me:

unset($array['element'])

I wrote a little test script, you can see the source at
http://www.antrophia.com/test.txt and the executable at
http://www.antrophia.com/test.php ... Now, if you look at the last part:

unset ($unserialized['foo']);
if (key_exists("foo", $unserialized)) { echo "foo exists!\n"; }
if (key_exists("wom", $unserialized)) { echo "wom exists!\n\n"; }

You will see that $unserialized['foo'] still exists! Can anyone explain me
what I'm doing wrong?

Thanks in advance,

Leon Mergen
