his article shows you how to use the most important iterator classes: ArrayIterator, DirectoryIterator, FilterIterator, and so forth, found in the Standard PHP Library (SPL), and how to integrate SPL with PHP Data Objects (PDO). The Standard PHP Library The SPL represents a collection of interfaces and classes for PHP 5 that help resolve some common problems and that let developers take full advantage of object-oriented programming. Some of the SPL's most used capabilities are: advanced array access, the ability to customize collection iteration with foreach or while, enhanced file and directory access, and advanced SimpleXML object handling. But the best new functionality that the SPL provides comes in the form of iterators. According to Wikipedia, an iterator is an object that allows a programmer to traverse through all the elements of a collection, regardless of its specific implementation.

PageRank In PHP
Google was a better search engine than it's predecessors for a number of reasons, but probably the most well known one is PageRank, the algorithm for measuring the importance of a page based on what links to it. Though not necessarily that useful on its own, this kind of link analysis can be very helpful as part of a general information retrieval system, or when looking at any kind of network, such as a friend graph from a social network. Larry Page came up with PageRank as a way of measuring the importance of a page while at Stanford in the mid nineties. The idea is that there is a random surfer, who starts on web page then browses through in a somewhat random way. For each page the surfer visits he randomly chooses one of the links from that page and follows it.This PHP tutorial will show how to create a simple PHP class to search the flickr site for some photos. To get the data we use the flickr API to run a simple search and return the results in a serialized array. We will be using the php function "file_get_contents" to receive data from flickr. The data which we will receive will be a serialized PHP array which means all we need to do is unserialize the array and we will easily be able to use the data returned. As an alternative we can use a cURL function to get the data, for example if the function "file_get_contents" is not allowed on your web host. API Authentication

SQL injection is a technique often used to attack data driven applications. [ 1 ] This is done by including portions of SQL statements in an entry field in an attempt to get the website to pass a newly formed rogue SQL command to the database (e.g., dump the database contents to the attacker). SQL injection is a code injection technique that exploits a security vulnerability in an application's software. The vulnerability happens when user input is either incorrectly filtered for string literal escape characters embedded in SQL statements or user input is not strongly typed and unexpectedly executed. SQL injection is mostly known as an attack vector for websites but can be used to attack any type of SQL database. In operational environments, it has been noted that applications experience an average of 71 attempts an hour. [ 2 ]

Type Hinting
People often ask about scalar/basic typehints. Here is a drop in class that I use in my MVC framework that will enable typehints through the use of a custom error handler. Note: You should include this code above all other code in your include headers and if you are the using set_error_handler() function you should be aware that this uses it as well. You may need to chain your set_error_handlers()PHP
