xref: /PHP-5.4/ext/pcre/pcrelib/testdata/testinput2 (revision 23917b45)
1/-- This set of tests is not Perl-compatible. It checks on special features
2    of PCRE's API, error diagnostics, and the compiled code of some patterns.
3    It also checks the non-Perl syntax the PCRE supports (Python, .NET,
4    Oniguruma). Finally, there are some tests where PCRE and Perl differ,
5    either because PCRE can't be compatible, or there is a possible Perl
6    bug.
7
8    NOTE: This is a non-UTF set of tests. When UTF support is needed, use
9    test 5, and if Unicode Property Support is needed, use test 7. --/
