# PL/php - PHP as a procedural language for PostgreSQL
#
# PGXS-based build.  Requires:
#   * PostgreSQL server development files (pg_config on PATH, or set PG_CONFIG)
#   * PHP (>= 8.0) built with the embed SAPI, non-thread-safe (php-config on PATH)
#
# Build & install:
#   make
#   sudo make install
#   (in a database) CREATE EXTENSION plphp;
#
# Run the regression tests against a running server:
#   make installcheck
