MYSQLI_STMT_BIND_RESULT(3)						 1						MYSQLI_STMT_BIND_RESULT(3)

mysqli_stmt::bind_result - Binds variables to a prepared statement for result storage

       Object oriented style

SYNOPSIS

       bool mysqli_stmt::bind_result (mixed  &$var1, [mixed  &$...])

DESCRIPTION

       Procedural style
       bool mysqli_stmt_bind_result (mysqli_stmt  $stmt, mixed	&$var1, [mixed	&$...])

	Binds columns in the result set to variables.

	When  mysqli_stmt_fetch(3) is called to fetch data, the MySQL client/server protocol places the data for the bound columns into the speci-
       fied variables $var1, ....

       Note

	       Note that all columns must be bound after mysqli_stmt_execute(3) and prior to calling  mysqli_stmt_fetch(3).  Depending	on  column
	      types bound variables can silently change to the corresponding PHP type.

	       A  column  can  be bound or rebound at any time, even after a result set has been partially retrieved. The new binding takes effect
	      the next time mysqli_stmt_fetch(3) is called.

PARAMETERS

	      o $
		stmt -Procedural style only: A statement identifier returned by mysqli_stmt_init(3).

	      o $var1
		- The variable to be bound.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Object oriented style

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

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

	      /* prepare statement */
	      if ($stmt = $mysqli->prepare("SELECT Code, Name FROM Country ORDER BY Name LIMIT 5")) {
		  $stmt->execute();

		  /* bind variables to prepared statement */
		  $stmt->bind_result($col1, $col2);

		  /* fetch values */
		  while ($stmt->fetch()) {
		      printf("%s %s
", $col1, $col2);
		  }

		  /* close statement */
		  $stmt->close();
	      }
	      /* close connection */
	      $mysqli->close();

	      ?>

       Example #2

	      Procedural style

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

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

	      /* prepare statement */
	      if ($stmt = mysqli_prepare($link, "SELECT Code, Name FROM Country ORDER BY Name LIMIT 5")) {
		  mysqli_stmt_execute($stmt);

		  /* bind variables to prepared statement */
		  mysqli_stmt_bind_result($stmt, $col1, $col2);

		  /* fetch values */
		  while (mysqli_stmt_fetch($stmt)) {
		      printf("%s %s
", $col1, $col2);
		  }

		  /* close statement */
		  mysqli_stmt_close($stmt);
	      }

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

	      The above examples will output:

	      AFG Afghanistan
	      ALB Albania
	      DZA Algeria
	      ASM American Samoa
	      AND Andorra
