dba_handlers

dba_handlers

(PHP 4 >= 4.3.0, PHP 5)

dba_handlersList all the handlers available

说明

array dba_handlers ([ bool $full_info = false ] )

dba_handlers() list all the handlers supported by this extension.

参数

full_info

Turns on/off full information display in the result.

返回值

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.

Note:

When the internal cdb library is used you will see cdb and cdb_make.

范例

Example #1 dba_handlers() Example

<?php

echo "Available DBA handlers: ";
foreach (
dba_handlers(true) as $handler_name => $handler_version) {
  
// clean the versions
  
$handler_version str_replace('$'''$handler_version);
  echo 
" - $handler_name$handler_version ";
}

?>

以上例程的输出类似于:

Available DBA handlers:
 - cdb: 0.75, Revision: 1.3.2.3 
 - cdb_make: 0.75, Revision: 1.2.2.4 
 - db2: Sleepycat Software: Berkeley DB 2.7.7: (08/20/99)
 - inifile: 1.0, Revision: 1.6.2.3 
 - flatfile: 1.0, Revision: 1.5.2.4
