mysql_drop_db - Drop (delete) a MySQL database

SYNOPSIS

       Warning

	      This  function  was deprecated in PHP 4.3.0, and will be removed in the future, along with the entirety of the original MySQL exten-
	      sion. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide  and  related  FAQ  for  more
	      information. Alternatives to this function include:

		     oExecute a
		       DROP DATABASE query

       bool mysql_drop_db (string  $database_name, [resource  $link_identifier = NULL])

DESCRIPTION

       mysql_drop_db(3)  attempts to drop (remove) an entire database from the server associated with the specified link identifier. This function
       is deprecated, it is preferable to use mysql_query(3) to issue an sql DROP DATABASE statement instead.

	      o $database_name
		- The name of the database that will be deleted.

	      o $
		link_identifier -The MySQL connection. If the link identifier is not specified,  the  last  link  opened  by  mysql_connect(3)	is
		assumed. If no such link is found, it will try to create one as if mysql_connect(3) was called with no arguments. If no connection
		is found or established, an E_WARNING level error is generated.

	Returns TRUE on success or FALSE on failure.

       Example #1

	      mysql_drop_db(3) alternative example

	      <?php
	      $link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
	      if (!$link) {
		  die('Could not connect: ' . mysql_error());
	      }

	      $sql = 'DROP DATABASE my_db';
	      if (mysql_query($sql, $link)) {
		  echo "Database my_db was successfully dropped
";
	      } else {
		  echo 'Error dropping database: ' . mysql_error() . "
";
	      }
	      ?>

       Warning

	       This function will not be available if the MySQL extension was built against a MySQL 4.x client library.

       Note

	       For backward compatibility, the following deprecated alias may be used: mysql_dropdb(3)

       mysql_query(3).

mysql_error - Returns the text of the error message from previous MySQL operation

SYNOPSIS

       Warning

	      This  extension  is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should
	      be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include:

		     omysqli_error(3)

		     o PDO::errorInfo

       string mysql_error ([resource  $link_identifier = NULL])

DESCRIPTION

	Returns the error text from the last MySQL function. Errors coming back from the MySQL database backend no longer issue warnings. Instead,
       use  mysql_error(3)  to	retrieve the error text. Note that this function only returns the error text from the most recently executed MySQL
       function (not including mysql_error(3) and mysql_errno(3)), so if you want to use it, make sure you check the value before calling  another
       MySQL function.

	      o $
		link_identifier  -The  MySQL  connection.  If  the  link  identifier is not specified, the last link opened by mysql_connect(3) is
		assumed. If no such link is found, it will try to create one as if mysql_connect(3) was called with no arguments. If no connection
		is found or established, an E_WARNING level error is generated.

	Returns the error text from the last MySQL function, or '' (empty string) if no error occurred.

       Example #1

	      mysql_error(3) example

	      <?php
	      $link = mysql_connect("localhost", "mysql_user", "mysql_password");

	      mysql_select_db("nonexistentdb", $link);
	      echo mysql_errno($link) . ": " . mysql_error($link). "
";

	      mysql_select_db("kossu", $link);
	      mysql_query("SELECT * FROM nonexistenttable", $link);
	      echo mysql_errno($link) . ": " . mysql_error($link) . "
";
	      ?>

	      The above example will output something similar to:

	      1049: Unknown database 'nonexistentdb'
	      1146: Table 'kossu.nonexistenttable' doesn't exist

       mysql_errno(3), MySQL error codes.
