Security of PHP scripts

Security of applications is one of the most important aspects of programming today - and one of the most overlooked and misunderstood. Now we will look at different security problems that face PHP developers and techniques to solve them.

PostgreSQL address book

We have looked extensively at interacting with the PostgreSQL relational database; now we look at integrating this into our ongoing project - a database-driven address book. First, we will have to create a table in the PostgreSQL database where we ca...

PHP and PostgreSQL

This column has been looking at ways to simplify the development of a database-driven Web-based address book. Now we look at a complete solution: the PostgreSQL Object Relational Database Management System (ORDBMS).

Address book in PHP revisited

In the last column we introduced the use of embedded databases within PHP via the Database Abstract (DBA) Layer. Now, we will re-implement Address Book 1 (AB1) using this superior technology.

Dealing with databases in PHP

Previously we have looked at building a basic address book database system. Address Book 1 stored its data in a flat file format - that is, plain text. The problem with storing data like this is that it is inefficient to search the entire address boo...

Searching address book data in PHP

We have looked at storing address book entries submitted by users. The other requirement of an address book is to be able to locate an address. Now we will look at parsing address book entries and matching a user-supplied string: a search engine.

Code deciphering

If you're considering developing programming skills in preparation for a career change, or are just interested in how software - from operating systems to games - is created, read on.

Advanced Processing of User Data in PHP

The previous column, 'Collecting user data' looked at how to accept data from basic HTML forms and store then in a structured format in a file. As this is such an important topic for those looking to become skilled in PHP development, we will revisit...

Collecting user data

There are two stages to receiving data from Web users: the first is to provide an interface to interact with, and the second is to retrieve this information. The most common way to do this is through the Common Gateway Interface (CGI), supported by P...

Strings and PHP

If you read the 'PHP Hypertext Preprocessor' column, you might have been wondering about some of the peculiarities of string handling with PHP. Strings, simply, consist of one or more characters in sequence. In PHP, $s = "string" creates a string var...

HP OfficeJet Pro 8730

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

Windows 10 / HP Spectre x360

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
