Outputing a Capitalized last value on an array

[tkruise]

<?php
$fruit['color'] = 'red';
$fruit['taste'] = 'bitter';
$fruit['size'] = 'big';
$fruit['name'] = 'giant strawberry';


//echo end($fruit); 			// outputs last value

$lastIndex = end($fruit); 	// creates a var to output the last value
echo strtoupper($fruit[$lastIndex]); //  Undefined index: giant strawberry  on line 11

//echo strtoupper(end($fruit)); //outputs a CAPS last value


?>

how come I'm getting this error right here, isn't the syntax completely right? ?

echo strtoupper($fruit[$lastIndex]); //  Undefined index: giant strawberry  on line 11

And on the last line everything goes fine?

echo strtoupper(end($fruit));

Well, you've chosen a strange name for your variable, which is what throws you off

echo $lastIndex;

which is most definitely not an index of $fruits. However

# This is now the last array index
$fruit['giant strawberry'] = 'yummy';

# And now this is...
$fruit['new_last_index'] = 'not a fruit';

# So this still has nothing to do with last index, but at least now there is an index
# matching the value of this variable
echo $fruit[$lastIndex];

And from the php documentation for [man]end[/man]

end() advances array's internal pointer to the last element, and returns its value.

Note that it says "value" not "key".
