mysqli_stmt_bind_result

Binds variables to a prepared statement for result storage (PHP 5)
bool mysqli_stmt_bind_result ( mysqli_stmt stmt, mixed &var1 [, mixed &...] )

Procedural style:

Object oriented style (method):

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

stmt

Procedural 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 1558. 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 1559. 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);
?>
