mysql_list_dbs
(PHP 4, PHP 5)
mysql_list_dbs — List databases available on a MySQL server
Description
Returns a result pointer containing the databases available from the current mysql daemon.
This function has been DEPRECATED as of PHP 5.4.0. Relying on this function is highly discouraged.
Parameters
- link_identifier
-
The MySQL connection. If the link identifier is not specified, the last link opened by mysql_connect() is assumed. If no such link is found, it will try to create one as if mysql_connect() was called with no arguments. If no connection is found or established, an E_WARNING level error is generated.
Return Values
Returns a result pointer resource on success, or FALSE on failure. Use the mysql_tablename() function to traverse this result pointer, or any function for result tables, such as mysql_fetch_array().
Examples
Example #1 mysql_list_dbs() example
<?php
// Usage without mysql_list_dbs()
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
$res = mysql_query("SHOW DATABASES");
while ($row = mysql_fetch_assoc($res)) {
echo $row['Database'] . "\n";
}
// Deprecated as of PHP 5.4.0
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
$db_list = mysql_list_dbs($link);
while ($row = mysql_fetch_object($db_list)) {
echo $row->Database . "\n";
}
?>
The above example will output something similar to:
database1 database2 database3

For backward compatibility, the following deprecated alias may be used: mysql_listdbs()
