PHP列出MySQL中所有数据库的方法

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：

<?phpdefine( "NL", "" );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 listecho "<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 Connectionmysql_free_result( $result );mysql_close( $conn );  ?>

希望本文所述对大家的php程序设计有所帮助。
