Why is My Debug Session Ending Without Pausing in PhpStorm with Xdebug on Ubuntu 20.04?
Overview
Encountering issues where the debug session terminates abruptly in PhpStorm when using Xdebug on Ubuntu 20.04 can be quite frustrating. This post aims to explore the potential root causes and possible resolutions to ensure your breakpoints are hit, and debugging sessions are paused as expected.
Common Causes
Configuration Issues
Misconfiguration in Xdebug settings or improper PhpStorm configuration can often lead to the debugger not hitting breakpoints. Ensuring that Xdebug is properly set up to communicate with PhpStorm is crucial.
PHP Version Compatibility
