It's specifically designed for Web site creation and is frequently being used to replace the functionality created by Perl to write CGI scripts. PHP's popularity and easier-to-learn appeal has spawned a new breed of programmer, those who are only familiar with and only use PHP.

My utmost thanks to Jessica, the love of my life, for just about everything. Zoe and Sam, for making my world a better place. Everyone at Peachpit Press for their support, for their dedication to putting out quality books, and for everything else they do to make all this happen.
The most excellent editor, Rebecca Gulick, for so many reasons. Liz Welch, for her spot-on copyediting and attention to detail. The production coordinator, Myrna Vladic, the compositor, Danielle Foster, the proofreader, Patricia Pane, and the indexer, Valerie Haynes Perry, who turn my mess of files into an actual book.
Alan Solis, for his very, very helpful technical review. Thomas Larsson, for his input on the design patterns chapter. Always helpful to get even one more extra set of eyes! And for doing so on such short notice! The readers, the readers, the readers! This new knowledge can range from how to do different things, how to improve on the basic things, and how other technologies intersect with PHP.
In short, I present to you several hundred pages of beyond-the-norm but still absolutely necessary and often cool tips and techniques. You already possess all the basic knowledge—you retrieve database query results in your sleep—but want to go further. The first three chapters cover advanced PHP knowledge in general: programming techniques, Web applications, and databases.
Those chapters all cover information that the average PHP programmer may not be familiar with but should be able to comprehend. The next six chapters focus on object-oriented programming. This section constitutes about half of the book.
OOP is explained starting with the fundamentals, then going into lots of advanced topics, and ending with plenty of real-world examples. I focus almost equally on the philosophies involved as on the coding itself so that, in the end, you will come away with not just how to do this or that but also how to apply the new skills and ideas to your own projects. Some later chapters also reference examples completed in earlier ones.
I do not discuss either of these subjects in this book and, to be frank, may not adhere to them perfectly. Of course, all of the code and writing has been refreshed, edited, and improved as needed. This book does assume complete comfort with standard PHP programming, in particular debugging your own scripts. For starters, this means a PHP-enabled server. As of this writing, the latest version of PHP was 5. I use MySQL for the examples, but you can use anything. Fortunately, PHP 5 comes with built-in support for many advanced features.
Should you have questions or problems, you can always search the Web or post a message in my support forums www. Support Web Site I have developed a Web site to support this book, available at www. For example, though you already know how to use arrays, you may not have mastered multidimensional arrays: creating them, sorting them, and so on. You have written your own functions by this point but may not understand how to use recursion and static variables. Multidimensional Arrays Because of their power and flexibility, arrays are widely used in all PHP programming.
One use of multidimensional arrays will be to create a nested to-do list. Sorting multidimensional arrays Sorting arrays is easy in PHP, thanks to the sort , ksort , and related functions. Using them, you can sort a one-dimensional array by key, by value, in reverse order, and so forth. To sort a multidimensional array, you define your own sort function and then tell PHP to use that function by invoking the built-in usort , uasort , or uksort function.
The function you define must take exactly two parameters and return a value indicating which parameter should be first in the sorted list. A negative or false value means that the first parameter should be listed before the second. A positive or true value means the second parameter should come first. A value of 0 indicates the parameters have the same value. PHP will continue sending the inner arrays to this function so that they may be sorted.
If you want to see this in detail, print the values being compared in the function. The usort function sorts by values but does not maintain the keys for the outermost array. When you use uasort , the keys will be maintained. When you use uksort , the sort is based on the keys. To sort on the second key in the preceding example, you would want to compare two strings. Or you could just use strcmp to perform a case-sensitive sort.
To sort a multidimensional array 1. This script defines a two-dimensional array, which is then sorted based upon the inner array values. If a negative value is returned, the first string comes before the second alphabetically; if a positive value is returned, the second string comes first. If 0 is returned, the strings are the same. One significant difference is that this example should perform a descending sort, listing the highest grades first.
This is easily accomplished: change the comparison operator from greater than to less than. Thus, if the first argument is less than the second, the value true is returned, which indicates the second argument should come first in the ordered list. If just usort was invoked, the sorting would drop those keys.
The array sorted by name. Failure to use uasort would cause the keys, which store meaningful values see Script 1. Complete the page:? Save the file as sort. Database-driven arrays If you think about it, most database queries return a multidimensional array.
Selecting multiple columns from multiple rows in a database results in a multidimensional array. To demonstrate this, the next example will create a database-driven, Web-based to-do list system. But this list needs to be nestable, where each item can have multiple steps. The result will be a tree-like structure, where each branch can have its own offshoots. How a nested to-do list looks as a tree. The task itself goes into a VARCHAR column, which you could also define as a text type if you wanted to allow for longer descriptions.
Two timestamp columns round out the table, one documenting when the task was added and another to indicate its completion. Three standard indexes are placed on columns that might be used in queries. This table represents the same data as in and. The next few pages will walk through the PHP script that adds new tasks to this table.
To add tasks to the database 1. Script 1. Tasks are added to the database using this script. Tasks can even be filed under other tasks using the drop-down menu.
The HTML form for adding tasks. It will come from the drop-down menu, which means that it should be an integer. The Filter extension was added to core PHP as of version 5. The menu will be populated from the list of existing tasks.
The first possible value will be 0, for tasks that are not subservient to other tasks. This array will store the tasks to be used in the second list. The page contains the list of tasks two times.
