mysqli_stmt::bind_result, mysqli_stmt_bind_result


Description

Object oriented stylebool mysqli_stmt::bind_result(mixed var1,
mixed ...);

Procedural stylebool mysqli_stmt_bind_result(mysqli_stmt stmt,
mixed var1,
mixed ...);

Binds columns in the result set to variables.

When mysqli_stmt_fetch is called to fetch data, the MariaDB client/server protocol places the data for the bound columns into the specified variables var1, ....Note

Note that all columns must be bound after mysqli_stmt_execute and prior to calling mysqli_stmt_fetch. 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 is called.

Parameters

stmt

Procedural style only: A statement identifier returned by mysqli_stmt_init.

var1

The variable to be bound.

Return Values

Returns TRUE on success or FALSE on failure.

Example 20.146. Object oriented style

<?php
$mysqli = new mysqli('localhost', 'my_user', 'my_password', 'world');
if (mysqli_connect_errno()) {
 printf('Connect failed: %s\n', mysqli_connect_error());
 exit();
}
/* prepare statement */
if ($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\n', $col1, $col2);
 }
 /* close statement */
 $stmt->close();
}
/* close connection */
$mysqli->close();
?>

Example 20.147. Procedural style

<?php
$link = mysqli_connect('localhost', 'my_user', 'my_password', 'world');
/* check connection */
if (!$link) {
 printf('Connect failed: %s\n', 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\n', $col1, $col2);
 }
 /* close statement */
 mysqli_stmt_close($stmt);
}
/* close connection */
mysqli_close($link);
?>
