m4_ref_title(m4_db Extensions,
    Using m4_db with PHP, PHP, ext/perl, dumpload/utility)

m4_p([dnl
A PHP 4 extension for this release of m4_db is included in the
distribution package.  It can either either link directly against the
installed m4_db library (which is necessary for running in a
non-Apache/mod_php4 environment), or against mod_db4, which provides
additional safety when running under Apache/mod_php4.])

m4_p([dnl
The PHP extension provides the following classes, which mirror the
standard m4_db C++ API.])

m4_indent([dnl
class Db4Env {
m4_indent([dnl
function Db4Env($flags = 0) {}
function close($flags = 0) {}
function dbremove($txn, $filename, $database = null, $flags = 0) {}
function dbrename($txn, $file, $database, $new_database, $flags = 0) {}
function open($home, $flags = DB_CREATE  | DB_INIT_LOCK | DB_INIT_LOG | DB_INIT_MPOOL | DB_INIT_TXN, $mode = 0666) {}
function remove($home, $flags = 0) {}
function set_data_dir($directory) {}
function txn_begin($parent_txn = null, $flags = 0) {}
function txn_checkpoint($kbytes, $minutes, $flags = 0) {}])
}
m4_blank
class Db4 {
m4_indent([dnl
function Db4($dbenv = null) {}	// create a new Db4 object using the optional DbEnv
function open($txn = null, $file = null, $database = null, $flags = DB_CREATE, $mode = 0) {}
function close() {}
function del($key, $txn = null) {}
function get($key, $txn = null, $flags = 0) {}
function pget($key, &$pkey, $txn = null, $flags = 0) {}
function get_type() {}	// returns the stringified database type name
function stat($txn = null, $flags = 0) {} // returns statistics as an as
function join($cursor_list, $flags = 0) {}
function sync() {}
function truncate($txn = null, $flags = 0) {}
function cursor($txn = null, flags = 0) {}])
}
m4_blank
class Db4Txn {
m4_indent([dnl
function abort() {}
function commit() {}
function discard() {
function id() {}
function set_timeout($timeout, $flags = 0) {}])
}
m4_blank
class Db4Cursor {
m4_indent([dnl
function close() {}
function count() {}
function del() {}
function dup($flags = 0) {}
function get($key, $flags = 0) {}
function pget($key, &$primary_key, $flags = 0) {}
function put($key, $data, $flags = 0) {}])
}])

m4_p([dnl
The PHP extension attempts to be "smart" for you by:])

m4_nlistbegin
m4_nlist([dnl
Auto-committing operations on transactional databases if no explicit
Db4Txn object is specified.])
m4_nlist([dnl
Performing reference and dependency checking to insure that all
resources are closed in the correct order.])
m4_nlist([dnl
Supplying default values for flags.])
m4_nlistend

m4_p([dnl
To install this PHP module linked against the mod_db4 framework, perform
the following steps:])

m4_indent([dnl
% phpize
% ./configure --with-db4=__LB__[]m4_db library installation directory__RB__ \
	--with-mod_db4=$APACHE_INCLUDEDIR
% make
% make install])

m4_p([dnl
Then, in your php.ini file add the following:])

m4_indent([extension=db4.so])

m4_p([dnl
This extension will now only run in a SAPI linked into Apache httpd
(mod_php4, most likely), and will take advantage of all of its
auto-recovery and handle-caching facilities.])

m4_p([dnl
To install this php module linked against the m4_db library and not the
mod_db4 framework, perform the following steps:])

m4_indent([dnl
% phpize
% ./configure --with-db4=__LB__[]m4_db library installation directory__RB__
% make
% make install])

m4_p([dnl
Then in your php.ini file add:])

m4_indent([dnl
extension=db4.so])
