Impact of PHP frameworks on application memory usage

CodeIgniter uses less memory than Laravel, in a web application with a simple user login system and a list of 1000 items, CodeIgniter's memory usage was 9.2 MB compared to Laravel's 15.6 MB. Factors include application size, features used, and server configuration. When choosing a framework, you should consider the specific requirements of your application. For applications that focus on memory usage, CodeIgniter may be better, while for applications that require complex functionality, Laravel may be more suitable.

PHP Framework Comparison: Memory Usage Impact

When developing web applications, choosing the right framework is extremely important. PHP frameworks can have a significant impact on an application's memory usage. Below, we’ll compare two popular PHP frameworks: Laravel and CodeIgniter, and examine their memory footprint.

Practical Case

To compare these two frameworks, we created two simple web applications:

• Laravel application : Contains a simple user login system and a list page containing 1000 items.
• CodeIgniter Application: Application with the same functionality and data volume.

Results

Using PHP’s built-in memory_get_usage() function, we measure on the first request of each application memory usage. The results look like this:

Framework	Memory Usage (MB)
Laravel	15.6
CodeIgniter	9.2

As we can see, CodeIgniter The memory usage was significantly reduced in this particular case. This may be due to the larger infrastructure that Laravel uses and features like service providers.

Influencing factors

The following factors may affect the memory usage of the PHP framework:

• Application size and complexity : Larger applications will require more memory.
• Features used: Some framework features (such as ORM and authentication) require additional memory overhead.
• Server Configuration: PHP memory limits and server resource availability also affect memory usage.

Choose the right framework

When choosing a PHP framework, it is crucial to consider the specific requirements of your application. For applications where memory usage is critical, CodeIgniter may be a better choice. However, for complex applications that require large infrastructure and rich functionality, Laravel may be a better choice.

Conclusion

The impact of the PHP framework on application memory usage cannot be ignored. By understanding the memory footprint of different frameworks, developers can make informed choices when making project decisions.
