Most oci8 tests fail out-of-the-box because a typical host won't have
an Oracle database instance available. Other database drivers like
mysqli and pgsql address this problem with an include file, inserted
into SKIPIF, that skips the test if no connection at all can be made.
This commits adds such a file (skipifconnectfailure.inc) for oci8, and
adds the corresponding SKIPIF to any tests that connect to a database.
Closes GH-11804
* ext/oci8/tests/lob_aliases.phpt: drop unnecessary SKIPIF.
This patch adds missing newlines, trims multiple redundant final
newlines into a single one, and trims redundant leading newlines in all
*.phpt sections.
According to POSIX, a line is a sequence of zero or more non-' <newline>'
characters plus a terminating '<newline>' character. [1] Files should
normally have at least one final newline character.
C89 [2] and later standards [3] mention a final newline:
"A source file that is not empty shall end in a new-line character,
which shall not be immediately preceded by a backslash character."
Although it is not mandatory for all files to have a final newline
fixed, a more consistent and homogeneous approach brings less of commit
differences issues and a better development experience in certain text
editors and IDEs.
