Install php-protobu extension and use

Install php-protobu extensions for php and use resources: https://github.com/allegro/php-protobuf/

Go to the extract directory and run phpize.

./Configure

Make

Make install

# Please add following line to your php. ini

Extension = protobuf. so

Restart PHP

Phpinfo () shows the protobuff extension.

How to use it?

Save

First, the proto file foo. proto file is created.

Message PhoneNumber {

Required string number = 1;

Required int32 type = 2;

}

Message Person {

Required string name = 1;

Required int32 id = 2;

Optional string email = 3;

Repeated PhoneNumber phone = 4;

}

Message AddressBook {

Repeated Person person = 1;

}

Then generate

Php protoc-php.php foo. proto

At this time, a pb_proto_foo.php file will be generated.

The specific application is as follows.

For example, to communicate with JAVA. Protobuffer stores the php file test. php, for example:

Require_once 'pb _ proto_test.php ';

$ Packed = curlGet ('http: // 10.0.247.113: 8080/testweb/proto'); // buffer information returned by JAVA

$ Foo = new AddressBook ();

Try {

$ Foo-> parseFromString ($ packed );

} Catch (Exception $ ex ){

Die ('parse error: '. $ e-> getMessage ());

}

$ Pb = $ foo-> getPerson ();

// Print_r ($ pb );

// Print_r ($ pb [0]);

Echo $ pb [0]-> getName (). '_'. $ pb [0]-> getId ().'_';

Print_r ($ pb [0]-> getPhone ());

PHP calls to modify buffer data

----------------------------

Require_once 'pb _ proto_test.php ';

$ Foo = new Person ();

$ Foo-> setName ('xiaoyun ');

$ Foo-> setId (200 );

$ Foo-> setEmail ('dofound @ 163.com ');

// $ Foo-> appendPhone (2 );

$ Packed = $ foo-> serializeToString ();

$ Foo-> clear ();

Try {

$ Xiao = $ foo-> parseFromString ($ packed );

// Print_r ($ xiao );

} Catch (Exception $ ex ){

Die ('upss .. there is a bug in this example ');

}

Echo $ foo-> getName ();

Echo $ foo-> getPhone ()-> number;

$ Foo-> dump ();

PHP internal call
