mysqli_stmt::bind_result
mysqli_stmt_bind_result
Binds variables to a prepared statement for result storage
Description
Object-oriented style
public bool mysqli_stmt::bind_result(mixed &$var, mixed &...$vars)
bool mysqli_stmt_bind_result(mysqli_stmt $statement, mixed &$var, mixed &...$vars)
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 var/vars.
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.
Note:
All columns must be bound after
mysqli_stmt_execute and prior to calling
mysqli_stmt_fetch.
Note:
Depending on column types bound variables can silently change to the
corresponding PHP type.
Tip
This function is useful for simple results. To retrieve iterable result
set, or fetch each row as an array or object,
use mysqli_stmt_get_result.
Parameters
-
statement
-
Procedural style only: A mysqli_stmt object
returned by mysqli_stmt_init.
-
var
-
The first variable to be bound.
-
vars
-
Further variables to be bound.
Return Values
Returns true on success or false on failure.
Examples
Example #1 Object-oriented style
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
/* prepare statement */
$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);
}
Example #2 Procedural style
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$link = mysqli_connect("localhost", "my_user", "my_password", "world");
/* prepare statement */
$stmt = mysqli_prepare($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);
}
