mysqli_result::data_seek - Adjusts the result pointer to an arbitrary row in the result

       Object oriented style

SYNOPSIS

       bool mysqli_result::data_seek (int  $offset)

DESCRIPTION

       Procedural style
       bool mysqli_data_seek (mysqli_result  $result, int  $offset)

	The mysqli_data_seek(3) function seeks to an arbitrary result pointer specified by the $offset in the result set.

PARAMETERS

	      o $
		result	 -Procedural   style   only:   A   result   set   identifier   returned   by  mysqli_query(3),	mysqli_store_result(3)	or
		mysqli_use_result(3).

	      o $offset
		- The field offset. Must be between zero and the total number of rows minus one (0..mysqli_num_rows(3) - 1).

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

NOTES

       Note

	       This function can only be used with buffered results attained from the use of the mysqli_store_result(3) or  mysqli_query(3)  func-
	      tions.

EXAMPLES

       Example #1

	      Object oriented style

	      <?php
	      /* Open a connection */
	      $mysqli = new mysqli("localhost", "my_user", "my_password", "world");

	      /* check connection */
	      if (mysqli_connect_errno()) {
		  printf("Connect failed: %s
", mysqli_connect_error());
		  exit();
	      }

	      $query = "SELECT Name, CountryCode FROM City ORDER BY Name";
	      if ($result = $mysqli->query($query)) {

		  /* seek to row no. 400 */
		  $result->data_seek(399);

		  /* fetch row */
		  $row = $result->fetch_row();

		  printf ("City: %s  Countrycode: %s
", $row[0], $row[1]);

		  /* free result set*/
		  $result->close();
	      }

	      /* close connection */
	      $mysqli->close();
	      ?>

       Example #2

	      Procedural style

	      <?php
	      /* Open a connection */
	      $link = mysqli_connect("localhost", "my_user", "my_password", "world");

	      /* check connection */
	      if (!$link) {
		  printf("Connect failed: %s
", mysqli_connect_error());
		  exit();
	      }

	      $query = "SELECT Name, CountryCode FROM City ORDER BY Name";

	      if ($result = mysqli_query($link, $query)) {

		  /* seek to row no. 400 */
		  mysqli_data_seek($result, 399);

		  /* fetch row */
		  $row = mysqli_fetch_row($result);

		  printf ("City: %s  Countrycode: %s
", $row[0], $row[1]);

		  /* free result set*/
		  mysqli_free_result($result);
	      }

	      /* close connection */
	      mysqli_close($link);
	      ?>

	      The above examples will output:

	      City: Benin City	Countrycode: NGA

mysqli_result::fetch_array - Fetch a result row as an associative, a numeric array, or both

       Object oriented style

SYNOPSIS

       mixed mysqli_result::fetch_array ([int  $resulttype = MYSQLI_BOTH])

DESCRIPTION

       Procedural style
       mixed mysqli_fetch_array (mysqli_result	$result, [int  $resulttype = MYSQLI_BOTH])

	Returns an array that corresponds to the fetched row or NULL if there are no more rows for the resultset represented by the $result param-
       eter.

       mysqli_fetch_array(3) is an extended version of the mysqli_fetch_row(3) function. In addition to storing the data in the numeric indices of
       the  result  array,  the mysqli_fetch_array(3) function can also store the data in associative indices, using the field names of the result
       set as keys.

       Note

	      Field names returned by this function are case-sensitive.

       Note

	      This function sets NULL fields to the PHP NULL value.

	If two or more columns of the result have the same field names, the last column will take precedence and overwrite the	earlier  data.	In
       order to access multiple columns with the same name, the numerically indexed version of the row must be used.

PARAMETERS

	      o $
		result	 -Procedural   style   only:   A   result   set   identifier   returned   by  mysqli_query(3),	mysqli_store_result(3)	or
		mysqli_use_result(3).

	      o $resulttype
		- This optional parameter is a constant indicating what type of array should be produced from the current row data.  The  possible
		values	for  this  parameter  are the constants MYSQLI_ASSOC, MYSQLI_NUM, or MYSQLI_BOTH.  By using the MYSQLI_ASSOC constant this
		function will behave identically to the mysqli_fetch_assoc(3), while MYSQLI_NUM will behave identically to the mysqli_fetch_row(3)
		function. The final option MYSQLI_BOTH will create a single array with the attributes of both.

RETURN VALUES

	Returns an array of strings that corresponds to the fetched row or NULL if there are no more rows in resultset.

EXAMPLES

       Example #1

	      Object oriented style

	      <?php
	      $mysqli = new mysqli("localhost", "my_user", "my_password", "world");

	      /* check connection */
	      if ($mysqli->connect_errno) {
		  printf("Connect failed: %s
", $mysqli->connect_error);
		  exit();
	      }

	      $query = "SELECT Name, CountryCode FROM City ORDER by ID LIMIT 3";
	      $result = $mysqli->query($query);

	      /* numeric array */
	      $row = $result->fetch_array(MYSQLI_NUM);
	      printf ("%s (%s)
", $row[0], $row[1]);

	      /* associative array */
	      $row = $result->fetch_array(MYSQLI_ASSOC);
	      printf ("%s (%s)
", $row["Name"], $row["CountryCode"]);

	      /* associative and numeric array */
	      $row = $result->fetch_array(MYSQLI_BOTH);
	      printf ("%s (%s)
", $row[0], $row["CountryCode"]);

	      /* free result set */
	      $result->free();

	      /* close connection */
	      $mysqli->close();
	      ?>

       Example #2

	      Procedural style

	      <?php
	      $link = mysqli_connect("localhost", "my_user", "my_password", "world");

	      /* check connection */
	      if (mysqli_connect_errno()) {
		  printf("Connect failed: %s
", mysqli_connect_error());
		  exit();
	      }

	      $query = "SELECT Name, CountryCode FROM City ORDER by ID LIMIT 3";
	      $result = mysqli_query($link, $query);

	      /* numeric array */
	      $row = mysqli_fetch_array($result, MYSQLI_NUM);
	      printf ("%s (%s)
", $row[0], $row[1]);

	      /* associative array */
	      $row = mysqli_fetch_array($result, MYSQLI_ASSOC);
	      printf ("%s (%s)
", $row["Name"], $row["CountryCode"]);

	      /* associative and numeric array */
	      $row = mysqli_fetch_array($result, MYSQLI_BOTH);
	      printf ("%s (%s)
", $row[0], $row["CountryCode"]);

	      /* free result set */
	      mysqli_free_result($result);

	      /* close connection */
	      mysqli_close($link);
	      ?>

	      The above examples will output:

	      Kabul (AFG)
	      Qandahar (AFG)
	      Herat (AFG)
