| Mobi | Page Kindle Locations 7472-7476 In the TIP section aliases |
Hello there, In the TIP section of Appendix B, Kindle Locations 7472-7476, the author suggests the creation of an alias like this one : I recommend you create command-line aliases for these Vagrant commands because you’ll type them a lot. Drop these into your ~/. bash_profile file and restart your terminal application: alias vi =" vagrant init" IMHO this is dangerous as it remaps a very common UNIX command: « vi » Perhaps a solution to this would be to create the aliases as « vai » instead of « vi ». All other alias examples could also be changed like this : alias vai =" vagrant init" alias vau =" sudo echo 'Starting VM' && vagrant up" alias vaup =" sudo echo 'Starting VM' && vagrant up --provision" alias vap =" vagrant provision" alias vah =" vagrant halt" alias vas =" vagrant ssh" That would prevent future issues for some people.

| Printed | Page 90 Example 5-13, 5-14 and especially 5-15 |
The code in these examples is actually valid but confusing because you are inconsistent with regards to global namespace. In 5-13 you do not preface `new DateTime` with a backslash but in 5-14 you use `new \DateTime`. And then in 5-15 you mix the two with sometimes prefix-ing with a backslash and sometimes without. I understand that when you do not declare a namespace it's optional but it's still a bit messy. Being a bit picky though. 5-14 is also a bit confusing as you have a 3 as the third argument for DatePeriod but the outputs give 4 items. Only after reading page 92 did you introduce EXCLUDE_START_DATE. That being said I am enjoying the book so far, so kudos! Cheers, Mike Note from the Author or Editor: |

I recommend changing "Never hard-code database credentials into PHP files, especially PHP files served to the public" to "Never hard-code database credentials into PHP files served to the public". The right way IS to hard-code into PHP files, but not public ones (as is shown lower on the page). Note from the Author or Editor: |

| Printed | Page 102 Under // Withdraw funds from account 1 code section |
$withDrawal should be $withdrawal in this line: $stmtSubtract->bindParam(':amount', $withDrawal, PDO::PARAM_INT); Nitpick: In this example money should be stored as a float and not as an integer. But seeing as there is no PDO::PARAM_FLOAT or PDO::PARAM_DOUBLE I see why you made it an int and punted instead of explaining. Note from the Author or Editor: |

in this phrase, The bootstrap.php file also specifies the path to our test suite (i.e., a directory that contains related test cases); ... I think the 'bootstrap.php file' should be 'phpunit.xml file'. because bootstrap.php file doesn't contain any configuration about test suite. isn't it? Note from the Author or Editor: |
