MYSQL_DATA_SEEK(3)							 1							MYSQL_DATA_SEEK(3)

mysql_data_seek - Move internal result pointer

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)

		     o PDO::FETCH_ORI_ABS

       bool mysql_data_seek (resource  $result, int  $row_number)

DESCRIPTION

       mysql_data_seek(3) moves the internal row pointer of the MySQL result associated with the specified result identifier to point to the spec-
       ified row number. The next call to a MySQL fetch function, such as mysql_fetch_assoc(3), would return that row.

       $row_number starts at 0. The $row_number should be a value in the range from 0 to mysql_num_rows(3) - 1. However if the result set is empty
       (mysql_num_rows(3) == 0), a seek to 0 will fail with a E_WARNING and mysql_data_seek(3) will return FALSE.

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

	      o $row_number
		- The desired row number of the new result pointer.

	Returns TRUE on success or FALSE on failure.

       Example #1

	      mysql_data_seek(3) example

	      <?php
	      $link = mysql_connect('localhost', 'mysql_user', 'mysql_password');
	      if (!$link) {
		  die('Could not connect: ' . mysql_error());
	      }
	      $db_selected = mysql_select_db('sample_db');
	      if (!$db_selected) {
		  die('Could not select database: ' . mysql_error());
	      }
	      $query = 'SELECT last_name, first_name FROM friends';
	      $result = mysql_query($query);
	      if (!$result) {
		  die('Query failed: ' . mysql_error());
	      }
	      /* fetch rows in reverse order */
	      for ($i = mysql_num_rows($result) - 1; $i >= 0; $i--) {
		  if (!mysql_data_seek($result, $i)) {
		      echo "Cannot seek to row $i: " . mysql_error() . "
";
		      continue;
		  }

		  if (!($row = mysql_fetch_assoc($result))) {
		      continue;
		  }

		  echo $row['last_name'] . ' ' . $row['first_name'] . "<br />
";
	      }

	      mysql_free_result($result);
	      ?>

       Note

	       The function mysql_data_seek(3) can be used in conjunction only with mysql_query(3), not with mysql_unbuffered_query(3).

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