Performance Improvements in PHP 8

PHP 8 comes with major performance improvements that significantly improve scripting Execution speed.

JIT Compiler

One of the most significant performance improvements in PHP 8 is the introduction of the JIT (Just-In-Time) compiler. The JIT compiler converts PHP code into machine code, thus avoiding the need for a PHP interpreter every time the code is executed. This can significantly speed up code execution, especially for compute-intensive tasks such as loops, function calls, and data processing.

Optimized memory management

Memory management has also been improved in PHP 8 to make it more efficient. A new memory model is introduced that allocates and frees memory more efficiently. In addition, optimizations have been made during the garbage collection process to reduce memory fragmentation and improve garbage collection efficiency.

DEPRECATED OLD EXTENSIONS

Many old extensions are deprecated in PHP 8 that are considered inefficient or no longer needed. This frees up a lot of overhead, allowing the PHP core to perform more efficiently.

Optimizing string handling

PHP 8 has optimized string handling, using an internal representation called string. This makes string operations more efficient, especially when working with large strings or performing complex string operations.

Other Optimizations

In addition to these major improvements, PHP 8 also includes many other small optimizations, including:

  • Improvements Function call overhead.
  • Optimized array processing.
  • Improved error handling efficiency.

Overall, the performance improvements of PHP 8 are considerable. According to official benchmarks, PHP 8 performs 10-30% faster than PHP 7.4, and in some cases even more.
