(PHP 4, PHP 5)
mysql_list_dbs — List databases available on a MySQL server
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.
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.
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().
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
Note:
For backward compatibility, the following deprecated alias may be used: mysql_listdbs()
