(PHP 5, PHP 7)
Binds variables to a prepared statement for result storage
bool mysqli_stmt::bind_result ( mixed &$var1 [, mixed &$... ] )

Object oriented style

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:

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.

Returns:

Returns TRUE on success or FALSE on failure.
