13 Apr 10 Common Errors In PHP Programmers Must Avoid
PHP is a server-side language widely used in static & dynamic web pages and web apps. It is very easy to create web pages in PHP; hence, it is trouble free to develop functional code in hours. However, no matter the level of skill sets, there are myriads of mistakes that PHP developers make while coding. The errors in web development can do a lot of damage and push the visitors away.
It is important to take care of the small mistakes to make your web development more flexible, secure and reliable. Here are 10 most error-prone places in PHP code that deserves your attention, curated from experience by experts from best Australia online pokies:
Here we added all ids in an array and passed to query by using implode that will convert the array of values to comma-separated values.
Use of quotes:It is common to use double quotes when concatenating strings because it parses everything neatly without having to deal with escaping characters and using dot values. However, using single quotes has considerable performance gains, as it requires less processing.
Consider this string:
Use of Semicolon: It’s funny how one little character can create havoc in a program, without even being reported to the PHP error logs! Such as it is with semicolons and While statements. Codeutopia has an excellent example of this little error, showing these nasty errors don’t even get reported (even to E_ALL!), as it quietly falls into a silent loop.
Adding Time Limits on Scripts: When you execute PHP scripts, it is considered that the script execution will finish promptly. It is not good to code on predictions.
You can observe this type of issue by setting up a time limit on the script (set_time_limit). It will be always good to know the config setting for execution time.
How to use Operators: A very small but very common mistake we all do while using the comparison operator. Sometimes we use “=” in place of comparison “==”. This mistake can change the value and logic of your code.
Rule to Rewrite URL’S: Rewriting of the URL is as important as all other security aspects of the project. You have to use URL creation using modern practice. Do not pass sensitive information as it is. Do not add many variables in the URL.
Validation and Controllers: Many times,you can see the developers adding validation in the controller itself. That is not good practice. In the few latest versions of framework like Laravel 5.0, if you add validation in the controller, you will get a fatal error. There are older versions also where this restriction is not added, you should take care of the code by not adding validations in the controller.
Configuration file: Most of the time developers start working even when you install any framework, it is mentioned that removing the config development file after the installation is done or giving full access to folders without taking care of the configuration file inside the folder. You do not have to do that. It is important to remove all configuration loopholes for hackers, who are distant to best online casino New Zealand due to its immense security.
Add Privileged access: Permitting users, groups and others are very important. You should not leak the super admin details to anyone outside. You should be very careful while adding permission to folders, files and database users.
As you all can see, it’s very easy to take care of these small mistakes and make web development more reliable and flexible. Take your time and ensure that your PHP code is clean, secure and running smoothly by avoiding these loopholes.
