Fix rare PclZip/realpath/PHP version problem

[andrew-kzoo]

In PHP 5.4.4 realpath() handles absolute paths correctly, but in PHP 5.3.8 returns false.

Note: PHP 5.4.4 and PHP 5.3.8 on Windows.

// PHP 5.4.4 - pass - returns original path
// PHP 5.3.8 - fail - returns false
$tempfile = tempnam(sys_get_temp_dir(), "PHPWORD");

echo realpath($tempfile);

Thanks @andrew-kzoo. I tried to find the reference of this PHP bug, but can't find one. What Windows version were you using? I'll try to reproduce the error.

[andrew-kzoo]

PHP 5.4.4 is running on Windows 7 Business Edition Service Pack 1
PHP 5.3.8 is running on Windows Server 2008 R2 Standard Edition Service Pack 1

I found a similar bug report which is older and no longer active: https://bugs.php.net/bug.php?id=41480

In advance, I understand this bug may be too narrow to have the fix included in PHPWord.

Ok, thanks for the info. I'll try to reproduce the bug this weekend.
