mysqli_bind_result (PHP 5 CVS only) mysqli_bind_result (no version information, might be only in CVS) stmt->bind_result -- Binds variables to a prepared statement for result storage DescriptionProcedural style: bool mysqli_bind_result ( object stmt, mixed var1 [, mixed var2, ...]) Object oriented style (method): class stmt { bool bind_result ( mixed var1 [, mixed var2, ...]) }
mysqli_bind_result() is used to associate (bind) columns in the result set to variables. When mysqli_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_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_fetch() is called.
Return values
Returns TRUE on success or FALSE on failure. ExampleExample 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_execute($stmt);
/* bind variables to prepared statement */
mysqli_bind_result($stmt, $col1, $col2);
/* fetch values */
while (mysqli_fetch($stmt)) {
printf("%s %s\n", $col1, $col2);
}
/* close statement */
mysqli_stmt_close($stmt);
}
/* close connection */
mysqli_close($link);
