mysqli_stmt::bind_result -- mysqli_stmt_bind_result — Binds variables to a prepared statement for result storage
Object-oriented style
Procedural style
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 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.
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().
statementProcedural style only: A mysqli_stmt object returned by mysqli_stmt_init().
varThe first variable to be bound.
varsFurther variables to be bound.
Example #1 Object-oriented style
<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
$stmt = $mysqli->prepare("SELECT Code, Name FROM Country ORDER BY Name LIMIT 5");
$stmt->execute();
$stmt->bind_result($col1, $col2);
while ($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");
$stmt = mysqli_prepare($link, "SELECT Code, Name FROM Country ORDER BY Name LIMIT 5");
mysqli_stmt_execute($stmt);
mysqli_stmt_bind_result($stmt, $col1, $col2);
while (mysqli_stmt_fetch($stmt)) {
printf("%s %s\n", $col1, $col2);
