[pkg-php-pear] Bug#1000593: Failing testsuite with PHP 8.1

[Bryce Harrington]

These tests fail due to changes in how objects are dumped, like the
ordering of members.  This seems to just be a formatting discrepancy.
Presumably the logical fix is to revise the expected output to match the
new output formatting style, or alternatively just disable the three
test cases until upstream has a chance to update to latest versions of
php, et al.
