Most of the time, you do not even need a whole lot of time to write unit tests with this method. Showing that a bug exists in code is pretty easy - if you assert what the outcome should be, and you get a different outcome, the unit test fails. Usually these tests take less than 30 minutes to write (and any test that takes more than 30 minutes to write by itself might be too large anyway). This strategy is also excellent when you have a large existing codebase that lacks unit tests. By writing them as you fix bugs, you will slowly improve your coverage.
On the other hand, in our first query (the SELECT * FROM guests part), we see that there are no possible keys, and thus it is not using any. We see that it is selecting four records as well. This is a problem, because without any keys, MySQL is not making use of its indices. The EXPLAIN has shown us the problem: if we are making frequent requests where we select based on the first name, we need to add an index on that column. 3 In this example, we see that EXPLAIN shows us MySQL only needs to request one record, because it knows exactly where the record is that we are hunting for.
An opcode cache takes the opcodes that are generated by the compiler and stores them, usually in memory, for retrieval at a later date. Based on the configuration, the opcode cache will, on the next request for that particular script, evaluate whether or not the script has changed on the disk. If the script is the same (as it most often will be), the opcode cache will provide the opcodes directly to the PHP engine, rather than allowing the script to be recompiled. This process saves time, since alreadycompiled code does not need to be recompiled.
