PHP Manual



(PHP 5)

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


Object oriented style

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

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() is called to fetch data, the MySQL client/server protocol places the data for the bound columns into the specified variables var1, ....


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.



Procedural style only: A statement identifier returned by mysqli_stmt_init().


The variable to be bound.

Return Values

Returns TRUE on success or FALSE on failure.


Example #1 Object oriented style

= new mysqli("localhost""my_user""my_password""world");

if (
mysqli_connect_errno()) {
printf("Connect failed: %s\n"mysqli_connect_error());

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

/* bind variables to prepared statement */

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

/* close statement */
/* close connection */


Example #2 Procedural style


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

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

/* bind variables to prepared statement */

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

/* close statement */

/* close connection */

The above examples will output:

AFG Afghanistan
ALB Albania
DZA Algeria
ASM American Samoa
AND Andorra
