Before
indulging in knowing what PHP developer does, let us know what PHP is
all about. PHP is an open source language that is often used by PHP
developers to create dynamic and stunning web pages. PHP builds core
LAMP bundle and this LAMP architecture is the one which is
extensively used in the PHP web application development. PHP
development then involves PHP software development and PHP web
development and it can be carried out through the platforms such as
MAC OS X, Windows and Linux. MySQL can be used along with PHP to
build applications that are driven by database.
There
are many offshore PHP development services companies that are focused
on dishing out their best to the clients with flexible options which
can bring them higher returns on investment. These services typically
include:
- Application Support
- Technical Enhancements
- New Add-ons to System
- System Up-gradation
- Code Review
- Application Optimization
- Bug Fixing
- Design Changes
- Functional Enhancements
Following
are certain things that any PHP developer can take into consideration
while creating PHP applications:
Use
PHP Core Functions and Classes: When as a developer, you are set to
create something which is very well known, you can take advantage of
an existing PHP function. Check the PHP manual function before
creating your own functions. There is no need to create a function to
remove the white space at the beginning and at the end of a string
when you can just use the trim() function. There is no need to build
an XML parser for RSS feeds when as PHP’s XML Parser functions
(such as xml_parse_into_struct)? can be enough.
Create
a Configuration File: Create one master file that contains database
connection settings and then include it in your PHP scripts? If you
need to change details later on, you can do it in one file instead of
several files. This is also very useful for a PHP developer when he
needs to use other constants and functions throughout multiple
scripts.
Using
a config file is a popular web application pattern that makes your
code more modular and easier to maintain.
Sanitize
Data That Will Go into Your Database: If you want to avoid problems
at a later phase, you need to sort out what are the popular ways in
which your application can be compromised. This way, you can get good
understanding of what SQL injections are. Then, you can read about
examples of SQL injection attacks and check SQL injection cheat
sheet. Expert PHP developers often resort to a PHP function that can
save the application from a big problem: mysql_real_escape_string.
mysql_real_escape_string will take a regular string (learn about data
types through this PHP variables guide) and sanitize it for you. If
you use the function together with htmlspecialchars, which converts
reserved HTML characters (like <script> becomes
<script>), not only will your database be protected,
but you will also safeguard your app against cross-site scripting
(XSS) attacks when rendering user-submitted HTML (such as those
posted in comments or forum threads).
