filter out the largest key in an array..

[nielskg]

Hi,

How do I filter out the largets/biggest key in an array?

Say I have this array :

Array (
[0] => Zero
[2] => Two
[4] => Four
}

Then the output should be 4...

Can this be done?

Thanx,
Niels

Hi,

You may try this:

$highest = 0;
while(list($no, $line) = each($NAME_OF_THE_ARRAY))
{
if($line > $highest)
$highest = $line;
}
echo $highest;

Yes, I have already found something similar:

krsort ($array);
reset ($array);
list ($key,$val) = each ($array);

where $key is the largest keynumber...
