MYSQLI_NUM_ROWS(3)							 1							MYSQLI_NUM_ROWS(3)

mysqli_result::$num_rows - Gets the number of rows in a result

       Object oriented style

SYNOPSIS

       int$mysqli_result->num_rows ()

DESCRIPTION

       Procedural style
       int mysqli_num_rows (mysqli_result  $result)

	Returns the number of rows in the result set.

	The  behaviour	of  mysqli_num_rows(3)	depends  on whether buffered or unbuffered result sets are being used. For unbuffered result sets,
       mysqli_num_rows(3) will not return the correct number of rows until all the rows in the result have been retrieved.

PARAMETERS

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

RETURN VALUES

	Returns number of rows in the result set.

       Note

	       If the number of rows is greater than PHP_INT_MAX, the number will be returned as a string.

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();
	      }

	      if ($result = $mysqli->query("SELECT Code, Name FROM Country ORDER BY Name")) {

		  /* determine number of rows result set */
		  $row_cnt = $result->num_rows;

		  printf("Result set has %d rows.
", $row_cnt);

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

	      /* 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();
	      }

	      if ($result = mysqli_query($link, "SELECT Code, Name FROM Country ORDER BY Name")) {

		  /* determine number of rows result set */
		  $row_cnt = mysqli_num_rows($result);

		  printf("Result set has %d rows.
", $row_cnt);

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

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

	      The above examples will output:

	      Result set has 239 rows.

mysqli_result::fetch_row - Get a result row as an enumerated array

       Object oriented style

SYNOPSIS

       mixed mysqli_result::fetch_row (void  )

DESCRIPTION

       Procedural style
       mixed mysqli_fetch_row (mysqli_result  $result)

	Fetches one row of data from the result set and returns it as an enumerated array, where each column is stored in an array offset starting
       from 0 (zero). Each subsequent call to this function will return the next row within the result set, or NULL if there are no more rows.

PARAMETERS

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

RETURN VALUES

       mysqli_fetch_row(3) returns an array of strings that corresponds to the fetched row or NULL if there are no more rows in result set.

       Note

	      This function sets NULL fields to the PHP NULL value.

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 DESC LIMIT 50,5";

	      if ($result = $mysqli->query($query)) {

		  /* fetch object array */
		  while ($row = $result->fetch_row()) {
		      printf ("%s (%s)
", $row[0], $row[1]);
		  }

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

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

       Example #2

	      Procedural style

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

	      /* check connection */

		  printf("Connect failed: %s
", mysqli_connect_error());
		  exit();
	      }

	      $query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";

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

		  /* fetch associative array */
		  while ($row = mysqli_fetch_row($result)) {
		      printf ("%s (%s)
", $row[0], $row[1]);
		  }

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

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