mysqli_stmt_bind_result() is used to associate (bind) columns in the result set to variables. When mysqli_stmt_fetch() is called to fetch data, the MySQL client/server protocol places the data for the bound columns into the specified variables var1, ....

Note: Note that all columns must be bound 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.

Return values

Returns TRUE on success or FALSE on failure.

Example

Example 1. 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 2. 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);

?>
