define()

[DigiRev]

You could just use a variable, but when I make something like a vars.php file to store settings, I personally use define().

Also, since "definitions"/constants, whatever, don't require you to use a $ sign, it helps distinguish them from other variables.

<?php
  define('DB_HOST','localhost');
  define('DB_USER','username');
  define('DB_PASS','password');
  define('DB_NAME','digirev');

  function db_connect() {
    $f_dbc = @mysql_connect(DB_HOST,DB_USER,DB_PASS) or die(mysql_error());
    mysql_select_db(DB_NAME) or die(mysql_error());
    return $f_dbc;
  }
?>
