+
+Building PHP Thrift Services with Apache
+========================================
+
+Thrift can be embedded in the Apache webserver with PHP installed. Sample
+code is provided below. Note that to make requests to this type of server
+you must use a THttpClient transport.
+
+Sample Code
+===========
+
+<?php
+
+namespace MyNamespace;
+
+/**
+ * Include path
+ */
+$THRIFT_ROOT = '/your/thrift/root/lib';
+
+/**
+ * Init Autloader
+ */
+require_once $THRIFT_ROOT . '/Thrift/ClassLoader/ThriftClassLoader.php';
+
+$loader = new ThriftClassLoader();
+$loader->registerNamespace('Thrift', $THRIFT_ROOT);
+$loader->registerDefinition('Thrift', $THRIFT_ROOT . '/packages');
+$loader->register();
+
+use Thrift\Transport\TPhpStream;
+use Thrift\Protocol\TBinaryProtocol;
+
+/**
+ * Example of how to build a Thrift server in Apache/PHP
+ */
+
+class ServiceHandler implements ServiceIf {
+  // Implement your interface and methods here
+}
+
+header('Content-Type: application/x-thrift');
+
+$handler = new ServiceHandler();
+$processor = new ServiceProcessor($handler);
+
+// Use the TPhpStream transport to read/write directly from HTTP
+$transport = new TPhpStream(TPhpStream::MODE_R | TPhpStream::MODE_W);
+$protocol = new TBinaryProtocol($transport);
+
+$transport->open();
+$processor->process($protocol, $protocol);
+$transport->close();

+
+# Using Thrift with PHP
+
+Thrift requires PHP 5. Thrift makes as few assumptions about your PHP
+environment as possible while trying to make some more advanced PHP
+features (i.e. APC cacheing using asbolute path URLs) as simple as possible.
+
+To use Thrift in your PHP codebase, take the following steps:
+
+1. Copy all of thrift/lib/php/lib into your PHP codebase
+2. Configure Symfony Autoloader (or whatever you usually use)
+
+After that, you have to manually include the Thrift package
+created by the compiler:
+
+```
+require_once 'packages/Service/Service.php';
+require_once 'packages/Service/Types.php';
+```
+
+# Dependencies
+
+PHP_INT_SIZE
+
+    This built-in signals whether your architecture is 32 or 64 bit and is
+    used by the TBinaryProtocol to properly use pack() and unpack() to
+    serialize data.
+

+# Breaking Changes
+
+## 0.12.0
+
+1. [PSR-4](https://www.php-fig.org/psr/psr-4/) loader is now the default. If you want to use class maps instead, use `-gen php:classmap`.
+
+2. If using PSR-4, use `$thriftClassLoader->registerNamespace('namespace', '<path>')` instead of `$thriftClassLoader->registerDefinition('namespace', '<path>')`.
