Returns an array of database handlers. If full_info
is set to TRUE
, the array will be associative with the handlers names as
keys, and their version information as value. Otherwise, the result will be
an indexed array of handlers names.
When the internal cdb library is used you will see
cdb
and cdb_make
.
<?php
echo "Available DBA handlers:\n";
foreach (dba_handlers(true) as $handler_name => $handler_version) {
// clean the versions
$handler_version = str_replace('$', '', $handler_version);
echo " - $handler_name: $handler_version\n";
}
?>
上例的输出类似于:
Available DBA handlers:

- cdb_make: 0.75, Revision: 1.2.2.4
- db2: Sleepycat Software: Berkeley DB 2.7.7: (08/20/99)
