说明

array dba_handlers ([ bool $full_info ] )

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

参数

full_info: Turns on/off full information display in the result. The default is FALSE .

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.

范例

Example#1 dba_handlers() Example

  <?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：

 - db2: Sleepycat Software: Berkeley DB 2.7.7: (08/20/99)
