Question

I have an array result like this,
example 1:

Array ( [0] =>15 [1] => 16 [2] => 17 [3] => 18 )

example 2:

Array ( [0] =>15 [1] => 16 [2] => 17 [3] => 18 [4] => 18 )

The first array ends at array[3]
The second array ends at array[4]
How to calculate where the array ends
Is there any function to calculate this

Answer 1

(Directly copied from http://www.php.net/manual/en/function.count.php)

Depending on what do you mean by “end”,

<?php
$yourArray = array(1=>'a', 7=>'b', 5=>'c');

print count($yourArray); // prints 3

end($yourArray);
print key($yourArray); // prints 5

print max(array_keys($yourArray)); // prints 7
?> 

For a normal array, just use count($a) - 1.
