Using Difference Utilities to Easily Compare PHP Extension Files Technology Articles | December 13 Wholesale Anders Bjork Jersey , 2008
PHP is a scripting language commonly used in the user interfaces of web pages. Using difference utilities, programmers can easily debug and compare PHP extension files.


PHP is a hypertext preprocessor or a scripting language that is well suited for web development. As a scripting language, the PHP code does not produce stand-alone programs, but instead can control the behavior of other programs and applications. It usually runs on web servers, and converts PHP code to web pages as output. As the PHP scripts get more complicated Wholesale Bobby Orr Jersey , sometimes it becomes necessary to compare PHP extension files, or that is, the actual code. Fortunately, utilities exist that can save programmers some labor and tedium.

PHP is used on a lot of web pages with dynamic content and user interaction. For example, the user interfaces of such websites as Facebook Wholesale David Pastrnak Jersey , Digg, Wordpress, Tagged, and Wikipedia are written in PHP.

Unless they know exactly where to look, this could be a difficult and tedious process of line by line comparison.

Hence, by highlighting the differences Wholesale Tuukka Rask Jersey , these difference utilities can help programmers immediately spot these differences and act on them if necessary.

A small typo or error somewhere could have big effects on the entire script, and it could be frustratingly difficult to find. By comparing the newer edited version with the older stable version, these changes could be more easily found. The error or typo could then be immediately put right.

These difference utilities could also be used as a learning aid for PHP programmers who are still starting out. By looking at the source code of a wide variety of web pages and making use of these difference programs in order to better spot the differences, a novice could learn a lot. Figuring out which command or block of code does which becomes easier, and this knowledge could be used in future programming.

All in all Wholesale Patrice Bergeron Jersey , these utilities make it much easier to compare PHP extension files. By saving programmers labor and tedium, these enable them to focus more on the logical structure and efficiency of the PHP code.
