Code optimization – optimize PHP code!

Code optimization is an essential part of building a website or application. You can use many techniques to optimize your code, but they all depend on what type of site you’re building and how much time you have available to optimize it. It would help if you always tried to follow these best practices while writing your codes:

Use include or require functions.

You can use include or require functions to include and require files in PHP. The include function is used to add a file in the current file, while the require function is used to load a file as a PHP module.

Include functions are faster than require functions because they don’t need any additional processing time on your server-side server (they only retrieve data from external servers).

Using the exact code

The exact code is the most recommended way to write your code. The following are some of the reasons why you should use the exact code:

  • It’s easier to read, write and maintain than any other method.
  • You can improve your skills by reading others’ work and writing better solutions.

Don’t use the global variables.

An essential part of writing code is keeping the variables you use local to the function they’re defined in. This will help prevent unexpected side effects, such as global variables polluting your application and causing errors when they shouldn’t be used.

It’s also a good idea to avoid using global functions if possible; this way, every function only has access to its own local variables instead of having access to other areas of your codebase or system (such as $_GET).

Use exec(), passthru(), system() functions only when you need them.

The exec() and passthru() functions can be used to execute a command line program, but they are not very efficient. They are also used in some cases where you do not need to use them at all.

In general, you should avoid using these functions unless you have no other choice:

  • Executes external commands on your server with one single call
  • Passes output of previous orders as variables to subsequent ones (e.g., echo $var)
  • Uses system() function as an alternative way of writing output directly into HTML or XML files

Use echo instead of print().

echo is a faster alternative to print(). It can be used for printing variable values, strings and HTML.

  • echo() will print the value of an expression on the screen. For example:
print("Hello World!"); //prints Hello World! to your browser window!

Use for each loop to read array elements in a loop.

  • Use foreach loop to read array elements in a loop.
  • The foreach loop is faster than a traditional for loop, because it does not have to read all of the data from the file and store it in memory before processing each item. It can also be used to read data from files, which is especially useful if you’re writing large amounts of code that involves reading files from multiple sources (such as database tables).

Always put a semicolon at the end of each statement.

Semicolons are used to separate statements in PHP. It’s an essential part of programming and should be included whenever possible. A semicolon can also be used at the end of a statement, but this is not always necessary:

Make sure that your code is correctly indented.

  • Use tabs or spaces to indent code. This is a simple rule, but it’s essential: you need to use the same number of tabs or spaces for each indentation level (1, 2 and so on). Don’t mix them up!
  • Use a tool to check your indentation. If you’re using Eclipse or Netbeans and want to make sure that your code is correctly indented, there are several tools available online that can help out with this task.

Code optimization techniques add up to the speed of your code and the overall performance of your website/app.

Code optimization techniques are not just for fun, they add up to the speed of your code and the overall performance of your website/app. The more you know about code optimization techniques, the better you can make a website or mobile app work.


As you can see, there are many different techniques that you can use to make your code more efficient. These techniques will not only improve the performance of your code, but they will also help you understand what is going on behind the scenes when someone uses it online.
