PHP Memory Profiling

Profiling a PHP page's memory usage is essential for identifying memory-intensive areas and optimizing your code. While xdebug's profiling feature lacks memory information, its tracing feature provides detailed memory deltas for function calls. However, the vast amount of data can be overwhelming.

Removed in xdebug 2.0

It's important to note that xdebug discontinued memory profiling support in version 2.0. For a viable alternative, consider the following options:
