How do I add to the end of an array and know how large the array is???????

Hi Arun,
If you want to add an element to an array you can always just use:
$arrayname[] = "$value";
However, if you want to know how many entries are in the array once you've done so, then you can get at that value simply by using the array_push function, like so:
<?php
$values = array("I","Like","Sentences","That","Don't");
$newelement = array_push($values,"Finish");
echo "There are now $newelement elements in the array:\n";
print_r($values);
?>
This prints out the following to the screen:
There are now 6 elements in the array:
Array
(
[0] => I
[1] => Like
[2] => Sentences
[3] => That
[4] => Don't
[5] => Finish
)
