mysqli_stmt_bind_result
(PHP 5)
mysqli_stmt_bind_result
(no version information, might be only in CVS)
stmt->bind_result() -- Binds variables to a prepared statement for result storage
Description
Procedural style:
bool
mysqli_stmt_bind_result ( mysqli_stmt stmt, mixed &var1 [, mixed &...] )
Object oriented style (method):
class
mysqli_stmt {
bool
bind_result ( 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
stmtProcedural 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.
Examples
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);
?>
