php issues

[funderburkjim]

In running this on a Linux server at Cologne, a couple of minor problems were noticed:

• At line 6 of presentable.php, using the backslash as path-separator doesn't work. Using forward slash works and likely will also work with PHP in Windows environment:

#include 'Emoji\src\Emoji\Emoji.php';
include 'Emoji/src/Emoji/Emoji.php';

• in get_issue_number.php, at lines 23 and 24, this syntax does not work with php 5.3.3:

explode(":",$val)[0]

These lines can easily be changed so that they work with the older php:

            $lower0 = explode(":",$val); $lower=$lower0[0];
            $upper0 = explode(":",$val);$upper = $upper0[1];
