Description:
------------
%p	UPPER-CASE 'AM' or 'PM' based on the given time
%P	lower-case 'am' or 'pm' based on the given time

These lines appear to be the wrong way around.

<?php
$date = '15/02/08 11:19:56 am';
$dateFormat1 = '%d/%m/%y %l:%M:%S %p'; // Little P, which docs say is upper-case
$dateFormat2 = '%d/%m/%y %l:%M:%S %P'; // Big P, which docs say is lower-case
echo strptime($date, $dateFormat1) == true ? "true\n" : "false\n";
echo strptime($date, $dateFormat2) == true ? "true\n" : "false\n";

Result is true, false, which means that %p is matching, but docs say it will 
only match on upper case, which is wrong and that %P is not matching, but docs 
say it will with the lower case.

Since the input has a lower case 'am' in it, the lower-case %P should match, but 
it does not.

Test script:
---------------
<?php
$date = '15/02/08 11:19:56 am';
$dateFormat1 = '%d/%m/%y %l:%M:%S %p'; // Little P, which docs say is upper-case
$dateFormat2 = '%d/%m/%y %l:%M:%S %P'; // Big P, which docs say is lower-case
echo strptime($date, $dateFormat1) == true ? "true\n" : "false\n";
echo strptime($date, $dateFormat2) == true ? "true\n" : "false\n";

Result is true, false, which means that %p is matching, but docs say it will only match on upper case, which is wrong and that %P is not matching, but docs say it will with the lower case.

Since the input has a lower case 'am' in it, the lower-case %P should match, but it does not.

Expected result:
----------------
false
true

Actual result:
--------------
true
false
