array dba_handlers ( [bool full_info] )

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

Parameters

full_info

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

Return Values

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.

Examples

Example 473. 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";
}

?>

The above example will output something similar to:
