mysql_result - Get result data

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_data_seek(3) in conjunction with mysqli_field_seek(3) and mysqli_fetch_field(3)

		     o PDOStatement::fetchColumn

       string mysql_result (resource  $result, int  $row, [mixed  $field])

DESCRIPTION

	Retrieves the contents of one cell from a MySQL result set.

	When working on large result sets, you should consider using one of the functions that fetch an entire row  (specified	below).  As  these
       functions return the contents of multiple cells in one function call, they're MUCH quicker than mysql_result(3). Also, note that specifying
       a numeric offset for the field argument is much quicker than specifying a fieldname or tablename.fieldname argument.

	      o $
		result -The result resource that is being evaluated. This result comes from a call to mysql_query(3).

	      o $row
		- The row number from the result that's being retrieved. Row numbers start at 0.

	      o $field
		- The name or offset of the field being retrieved.  It can be the field's offset, the field's name, or the field's table dot field
		name (tablename.fieldname). If the column name has been aliased ('select foo as bar from...'), use the alias instead of the column
		name. If undefined, the first field is retrieved.

	The contents of one cell from a MySQL result set on success, or FALSE on failure.

       Example #1

	      mysql_result(3) example

	      <?php
	      $link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
	      if (!$link) {
		  die('Could not connect: ' . mysql_error());
	      }
	      if (!mysql_select_db('database_name')) {
		  die('Could not select database: ' . mysql_error());
	      }
	      $result = mysql_query('SELECT name FROM work.employee');
	      if (!$result) {
		  die('Could not query:' . mysql_error());
	      }
	      echo mysql_result($result, 2); // outputs third employee's name

	      mysql_close($link);
	      ?>

       Note

	       Calls to mysql_result(3) should not be mixed with calls to other functions that deal with the result set.

       mysql_fetch_row(3), mysql_fetch_array(3), mysql_fetch_assoc(3), mysql_fetch_object(3).

mysql_db_query - Selects a database and executes a query on it

SYNOPSIS

       Warning

	      This  function  was deprecated in PHP 5.3.0, 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:

		     omysqli_select_db(3) then the query

		     o PDO::__construct

       resource mysql_db_query (string	$database, string  $query, [resource  $link_identifier = NULL])

DESCRIPTION

       mysql_db_query(3) selects a database, and executes a query on it.

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

	      o $query
		- The MySQL query.  Data inside the query should be properly escaped.

	      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 a positive MySQL result resource to the query result, or FALSE on error. The function also returns TRUE/ FALSE for INSERT/ UPDATE/
       DELETE queries to indicate success/failure.

       Example #1

	      mysql_db_query(3) alternative example

	      <?php

	      if (!$link = mysql_connect('mysql_host', 'mysql_user', 'mysql_password')) {
		  echo 'Could not connect to mysql';
		  exit;
	      }

	      if (!mysql_select_db('mysql_dbname', $link)) {
		  echo 'Could not select database';
		  exit;
	      }

	      $sql    = 'SELECT foo FROM bar WHERE id = 42';
	      $result = mysql_query($sql, $link);

	      if (!$result) {
		  echo "DB Error, could not query the database
";
		  echo 'MySQL Error: ' . mysql_error();
		  exit;
	      }

	      while ($row = mysql_fetch_assoc($result)) {
		  echo $row['foo'];
	      }

	      mysql_free_result($result);

	      ?>

       Note

	       Be aware that this function does NOT switch back to the database you were connected before. In other  words,  you  can't  use  this
	      function	to  temporarily run a sql query on another database, you would have to manually switch back. Users are strongly encouraged
	      to use the database.table syntax in their sql queries or mysql_select_db(3) instead of this function.

       mysql_query(3), mysql_select_db(3).
