This directory contains the Protocol Buffers runtime implementation via both a pure PHP package and a native c extension. The pure PHP package is intended to provide usability to wider range of PHP platforms, while the c extension is intended to provide higher performance. Both implementations provide the same runtime APIs and share the same generated code. Users don’t need to re-generate code for the same proto definition when they want to switch the implementation later.
Both implementations make use of generated PHP code that defines message and enum types in PHP. We strongly recommend using protoc's PHP generation support with .proto files. The build process in this directory only installs the extension/package; you need to install protoc as well to have PHP code generation functionality.
Requirements
To use PHP runtime library requires:
- C extension: PHP 5.5.x or 5.6.x.
- PHP package: PHP 5.5, 5.6 or 7.
Installation
C Extension
Prerequirements
To install the c extension, the following tools are needed:
- autoconf
- automake
- libtool
- make
- gcc
- pear
- pecl
On Ubuntu, you can install them with:
sudo apt-get install php-pear php5-dev autoconf automake libtool make gcc
On other platforms, please use the corresponding package managing tool to install them before proceeding.
Installation from Source (Building extension)
To build the c extension, run the following command:
cd ext/google/protobuf
pear package
sudo pecl install protobuf-{VERSION}.tgz
Installation from PECL
When we release a version of Protocol Buffers, we will upload the extension to PECL. To use this pre-packaged extension, simply install it as you would any other extension:
sudo pecl install protobuf-{VERSION}
PHP Package
Installation from composer
Simply add "google/protobuf" to the 'require' section of composer.json in your project.
Protoc
Once the extension or package is installed, if you wish to generate PHP code
from a .proto file, you will also want to install the Protocol Buffers
compiler (protoc), as described in this repository's main README file. The
version of protoc included in the latest release supports the --php_out
option to generate PHP code:
protoc --php_out=out_dir test.proto
Usage
For generated code: https://developers.google.com/protocol-buffers/docs/reference/php-generated
Known Issues
- Missing native support for well known types.
- Missing support for proto2.
- No API provided for clear/copy messages.
- No API provided for encoding/decoding with stream.
- Map fields may not be garbage-collected if there is cycle reference.
- No debug information for messages in c extension.
- HHVM not tested.
- C extension not tested on windows, mac, php 7.0.
- Message name cannot be Empty.
