stmt->bind_result -- Binds variables to a prepared statement
for result storage
Description
Procedural style:
bool mysqli_stnt_bind_result ( object stmt, mixed var1
[, mixed var2, ...])
Object oriented style (method):
class stmt {
bool bind_result ( mixed var1 [, mixed var2, ...])
}
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);
?>
