PHP Extension 5.17.2 released

  • New Feature: Tideways now indicates when session_write_close() was called.
  • Bugfix: Profiler::triggerCallgraphOn() now checks callgraph-mode preconditions within the callback instead of during registration, resulting in a more predictable behavior.
  • Bugfix: Fix possible crash when calling Profiler::disableCallgraphProfiler() from within an autoloader.

Tim Düsterhus

I’m a Software Engineer at Tideways, where I work on the PHP extension. My focus is on helping developers gain accurate insights into the runtime behavior of their applications with minimal overhead.

I’m interested in PHP internals and regularly contribute performance improvements to the PHP engine. I enjoy working on problems where small changes can have a measurable impact on the performance and efficiency of PHP applications. Several of my performance optimizations have become part of PHP itself, helping improve the language for developers worldwide.
