本文实例讲述了PHP列出MySQL中所有数据库的方法。分享给大家供大家参考。具体如下：

PHP代码如下：

<?php

define( 'NL', "\n" );

define( 'TB', ' ' );

// connecting to MySQL.

$conn = @mysql_connect( 'localhost', 'username', 'password' )

or die( mysql_errno().': '.mysql_error().NL );

// attempt to get a list of MySQL databases

// already set up in my account. This is done

// using the PHP function: mysql_list_dbs()

$result = mysql_list_dbs( $conn );

// Output the list

echo '<ul class="projects">'.NL;

///* USING: mysql_fetch_object()

// ---------------------------

while( $row = mysql_fetch_object( $result ) ):

echo TB.'<li>'.$row->Database.'</li>'.NL;

endwhile;

//*/

/* USING: mysql_fetch_row()

// ------------------------

while( $row = mysql_fetch_row( $result ) ):

echo TB.'<li>'.$row[0].'</li>'.NL;

endwhile;

//*/

/* USING: mysql_fetch_assoc()

// --------------------------

while( $row = mysql_fetch_assoc( $result ) ):

echo TB.'<li>'.$row['Database'].'</li>'.NL;

endwhile;

//*/

echo '</ul>'.NL;

// Free resources / close MySQL Connection

mysql_free_result( $result );

mysql_close( $conn );

?>
