# SymfonyCasts

PHP

SymfonyCasts is an e-learning platform of the Symfony community. In partnership with Blackfire, they developed a training course on PHP profiling and performance testing.

This course is available at no cost, and provides training material applicable to any PHP project, even though the examples run on Symfony.
