-----------------------------------------
Summary: Cache function_exists() capability checks in PHP runtime
hot paths
Key: THRIFT-5984
URL: https://issues.apache.org/jira/browse/THRIFT-5984
Project: Thrift
Issue Type: Improvement
Components: PHP - Library
Reporter: Volodymyr Panivko
In `lib/php/lib/Serializer/TBinarySerializer.php` and
`lib/php/lib/Transport/TSocket.php` the runtime calls `function_exists()` on
every serialize / deserialize / open() — checking for the same C-extension and
socket functions whose presence is a static property of the PHP installation.
Memoize these checks via `private static ?bool` flags initialized with the
null-coalescing assignment operator (`??=`). One-time lookup per process,
identical behavior.
Follow-up to THRIFT-5981 / THRIFT-5983 under the umbrella THRIFT-5960 (PHP
modernization).
