mysql_list_dbs

(PHP 4, PHP 5)

mysql_list_dbs — List databases available on a MySQL server

Warning

This function was deprecated in PHP 5.4.0, and it and the entire original MySQL extension was removed in PHP 7.0.0. Instead, use either the actively developed MySQLi or PDO_MySQL extensions. See also the MySQL: choosing an API guide. Alternatives to this function include:

• SQL Query: SHOW DATABASES

Description

Parameters

link_identifier

The MySQL connection. If the link identifier is not specified, the last link opened bymysql_connect() is assumed. If no such link is found, it will try to create one as if mysql_connect() had been called with no arguments. If no connection is found or established, an**[E_WARNING](errorfunc.constants.php#constant.e-warning)** level error is generated.

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=mysqlfetchassoc(row = mysql_fetch_assoc(row=mysqlf​etcha​ssoc(res)) {
echo $row['Database'] . "\n";
}// Deprecated as of PHP 5.4.0
$link = mysql_connect('localhost', 'mysql_user', 'mysql_password'); dblist=mysqllistdbs(db_list = mysql_list_dbs(dbl​ist=mysqll​istd​bs(link);

while ( row=mysqlfetchobject(row = mysql_fetch_object(row=mysqlf​etcho​bject(db_list)) {
echo $row->Database . "\n";
}
?>`

The above example will output something similar to:

database1 database2 database3
