1. introduction the role of Erlang extended term format (Erlangexternaltermformat) binary has been introduced in Erlang's term_to_binary data packaging system, some students want to use the term_to_binary function package to store Erlang data in binary format. 1. Introduction: Erlang extended term format (erlang external term format) some students want to use the term_to_binary function package to store Erlang data into the database in binary format, and then use PHP to read and decompress the package into a PHP array. To solve the problems encountered in the above application scenarios, refer to the peb (Php-Erlang Bridge) extension to write this binary extension similar to the erlang: binary_to_term/1 function, it can be understood as the binary_to_term of PHP. 2. Introduction to binary extensions 2.1. this binary extension exports the following functions: array binary_to_term (string $ binary) returns the array after unpacking. Int binary_errno () returns the error code generated by the last call of binary_to_term. 0 indicates no error, and 1 indicates the unsupported data type in binary content. String binary_error () returns the error message generated by the last call of binary_to_term. If no error exists, it is null. 2.2. binary extension module: http://download.csdn.net/download/u011471961/6447631 3. Install On * nux: Step 1: --------- unzip binary.zip cd. /binaryphpize or phpize5 Step 2: --------- check the Erlang installation directory and php-config path before executing configure. The configure below is just an example and can be modified according to the actual path. Install :. /configure CC = "gcc-L/usr/local/lib/erlang/lib/erl_interface-3.7.11/lib-I/usr/local/lib/erlang/lib/erl_interface-3.7.11/include "-- enable-binary -- with-php-config =/usr/local/php/bin/php-configOR :. /configure CC = "gcc-L/usr/local/lib/erlang/lib/erl_interface-3.7.11/lib-I/usr/local/lib/erlang/lib/erl_interface-3.7.11/include "-- enable-binary -- with-php-config =/usr/bin/php-config5 install on an Apple computer: Sudo MACOSX_DEPLOYMENT_TARGET = 10.7 CFLAGS = "-arch i386-arch x86_64-g-OS-pipe-no-cpp-precomp" CCFLAGS = "-arch i386-arch x86_64-g-OS- pipe "CXXFLAGS ="-arch i386-arch x86_64-g-OS-pipe "LDFLAGS ="-arch i386-arch x86_64-bind_at_load ". /configure CC = "gcc-m32-L/usr/local/lib/erlang/lib/erl_interface-3.7.6/lib-I/usr/local/lib/erlang/lib/erl_interface-3.7.6/include "-- enable-binary Step 3: --- ------ Make Step 4: --------- make test Step 5: --------- make install Step 6: --------- modify php. ini file: extension = binary. soOR: extension =/path/to/binary. so Step 7: --------- restart php-cgi or apache Step 8: --------- use the phpinfo () function or command (php-m) to check whether the binary module is loaded. 4. binary extension example 4.1: CREATE a mysql data TABLE [SQL] CREATE TABLE IF NOT EXISTS 'test' ('id' int (11) NOT NULL AUTO_INCREMENT, 'bin' varbinary (255) not null, primary key ('id') ENGINE = InnoDB default charset = utf8 AUTO_INCREMENT = 1; 4.2 write Data in Erlang [plain] test ()-> Data = [{name, rolong}, {phone, 888888}], Bin = term_to_binary (Data ), % the interface for writing data to the database depends on your own situation. db: execute (<"insert test (bin) values (~ S); ">>, [Bin]). 4.3. Read and decompress the package in PHP into a PHP array [php] GetOne ($ SQL); $ data = binary_to_term ($ bin); echo'
'; var_dump($data); echo '
'; Output [php] array (1) {[0] => array (2) {[0] => array (2) {[0] => string (4) "name" [1] => string (6) "rolong"} [1] => array (2) {[0] => string (5) "phone" [1] => int (888888 )}}}
