How to minimize coding errors in PHP

It’s a dream or challenge to every coder to write error free code. Sometimes a small mistake leads to a big error and we lose lot’s of time to identify it.

If we follows some basic rules to write code then we can minimize the errors in our code in PHP

Always define a default value for each variable

This is a very common mistake by developers. They never initialize the variables and in some conditions code throws an error. The best practice is always initialize all your variables before using them .

Always check variable having data or not before any loop

This is also a very common mistake that developers directly use any array into the loop without checking that variable having the data or not and this causes a warning.

Whenever you are using any loop first we need to confirm that variable contains the data.

Always use isset before getting any variable

As I mentioned before, always define or initialize your variable before using it. Use isset this is a predefined function in PHP which checks whether a variable is set or not.This function returns if the variable exists and not null, else it returns false.

Reuse your code

Always use the DRY method while you write the code. DRY stands for DO NOT REPEAT YOURSELF. It’s a principle of software development to avoid and minimize repetition of code and reduce redundancy. It will minimize your errors, organize your code and make your code robust and reusable.

Use meaningful variable name 

Never ever use random variable names in your programming. Use meaningful and relative names so that you and any other person can understand the code. Random names increase the complexity of the project and it’s hard to find exact code.

By using all above methods you can minimize the errors.
