  • pg_dbname()

    (PHP 4, PHP 5, PHP 7)

    获得数据库名

    说明

    pg_dbname(resource $connection): string

    pg_dbname()返回给定 PostgreSQL$connection资源的数据库名称。如果$connection不是有效的 PostgreSQL 连接资源则返回FALSE

    Example #1 pg_dbname()例子

    <?php
        error_reporting(E_ALL);
        pg_connect("host=localhost port=5432 dbname=mary");
        echo pg_dbname(); // mary
    ?>
    
    This function is as simple as it sounds, it returns the name of the database your are currently connected to on the handle retrieved from a pg_connect() call.
    <?php
      $pgsql_conn = pg_connect("dbname=mark host=localhost");
      if ($pgsql_conn) {
        print "Successfully connected to database: " . pg_dbname($pgsql_conn) .
         " on " . pg_host($pgsql_conn) . "<br/>\n";
      } else {
        print pg_last_error($pgsql_conn);
        exit;
      }
    ?>
    [mark@prodigy][*][~/public_html/php]>>>php pg_dbname.php
    Content-type: text/html
    X-Powered-By: PHP/4.3.1
    Successfully connected to database: mark on localhost<br/>
    Again this function is much more useful when you are changing which database you are connected to in your program.
