+# 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.
+
+apc_fetch(), apc_store()
+
+    APC cache is used by the TSocketPool class. If you do not have APC installed,
+    Thrift will fill in null stub function definitions.
+
+# 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>')`.
