This table lists core PHP functions and methods and specifies whether or not they are called from
a PHPT test. A "yes" in this table for a particular method is not an indication of good test coverage
- it just means that that method is called from at least one PHPT test.
The analysis used to generate this table does not differentiate between methods of the same name
belonging to different classes. In cases where such a method call is detected, "verify" is listed
in the Tested column, along with the list of test files containing calls to a method of that name.
