Why is the closing ?> tag absent from the PHP files included in the book's downloadable code? (The opening <?php is present, but not the closing ?> tag.)

composer commands

Using Composer version 1.6.2 2018-01-05 for Windows, the two composer commands shown on page 62 must not have the trailing semicolon; otherwise composer issues an InvalidArgumentException: C:\...\url-scanner-app>composer require guzzlehttp/guzzle; [InvalidArgumentException] Could not find package guzzlehttp/guzzle;. Did you mean one of these? guzzlehttp/guzzle puzzlehttp/puzzle guzzle/guzzle guzzlehttp/guzzle-services forknetwork/guzzle3

I made a mistake; disregard my previous submission because the book is correct.as-is regarding Composer's global credentials being saved in %APPDATA%/Composer.

2nd paragraph

The text describing Example 5-1 uses "The second argument is the ENT_QUOTES constant, which prompts the function to encode single quotes." when in fact this constant "Will convert both double and single quotes." according to the manual.

2nd paragraph

It's incorrect to use "zip code" -- the correct usage is ZIP Codeā„¢ (first instance; 'ZIP Code' for subsequent instances).

User Profile Information (p. 78) & Validate Data (p. 79)

Page 78 mentions filter_var() and filter_input(), and Examples 5-3, 5-4, and 5-5 illustrate filter_var() usage; why did you not include at least one example of filter_input() usage?

Escape Output

You may want to mention this regarding "specify the appropriate character encoding (usually UTF-8) as the third argument": [Quoted from PHP manual] default_charset string In PHP 5.6 onwards, "UTF-8" is the default value and its value is used as the default character encoding for htmlentities(), html_entity_decode() and htmlspecialchars() if the encoding parameter is omitted.

Line 10 of Example 5-7

Line 10 does not use the optional third parameter ('filter'). In this case, according to the PHP manual: If omitted, FILTER_DEFAULT will be used, which is equivalent to FILTER_UNSAFE_RAW. This will result in no filtering taking place by default. So one or more filter flags should be added to filter_input() on line 10.

Lines 17-19

Lines 17-19 should be indented four spaces (not three) per PSR-2, 2.4 Indenting. See also 4.6. Method and Function Calls, whose second example indents four spaces.

Example 5-8 lines 5 and 8

As separately reported for Example 5-7, filter_input() is missing one or more filter flags. E.g., compare Example 5-7 line 4 (page 83) with Example 5-8 line 5 (page 85).

Code at top of page 97; Examples 5-20, 5-21, 5-22, 5-23, 5-24, and 5-25

As separately reported for Examples 5-7 & 5-8, filter_input() is missing one or more filter flags.

Examples 5-26 & 5-27

Example 5-19 on page 96 uses include('../settings.php') while examples 5-26 & 5-27 use require 'settings.php'. ../settings.php is correct because this file must be located outside the document root.

Printed Page 106 & 107

The penultimate paragraph on page 106 uses http: for the URL while the first paragraph under Stream Wrappers on page 107 uses https:. Both URLs work of course; it's just a matter of consistency.

Example 5-35

Should class DirtyWordsFilter extends php_user_filter be this instead class DirtyWordsFilter extends \php_user_filter since this new class would presumably reside in its own namespace?

Example 5-44

Example 5-19 shows the proper way to handle confidential credentials; so I have to wonder why Example 5-44 does not follow suit? IMO Example 5-44 should be rewritten to include a separate settings.php file for the username and password credentials, and the email names and addresses.

phpmentoring.org is not what's described under Mentoring. Did you mean php-mentoring.org?
