mysqli_stmt_execute

(PHP 5, PHP 7, PHP 8)

mysqli_stmt::execute -- mysqli_stmt_executeExecutes a prepared statement

Description

Object-oriented style

public mysqli_stmt::execute(?array $params = null): bool

Procedural style

mysqli_stmt_execute(mysqli_stmt $statement, ?array $params = null): bool

Executes previously prepared statement. The statement must be successfully prepared prior to execution, using either the mysqli_prepare() or mysqli_stmt_prepare() function, or by passing the second argument to mysqli_stmt::__construct().

If the statement is UPDATE, DELETE, or INSERT, the total number of affected rows can be determined by using the mysqli_stmt_affected_rows() function. If the query yields a result set, it can be fetched using mysqli_stmt_get_result() function or by fetching it row by row directly from the statement using mysqli_stmt_fetch() function.

Parameters

statement

Procedural style only: A mysqli_stmt object returned by mysqli_stmt_init().

params

An optional list array with as many elements as there are bound parameters in the SQL statement being executed. Each value is treated as a string.

Return Values

Returns true on success or false on failure.

Changelog

Version Description
8.1.0 The optional params parameter has been added.

Examples

Example #1 Execute a prepared statement with bound variables

Object-oriented style

<?php

mysqli_report
(MYSQLI_REPORT_ERROR MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost""my_user""my_password""world");

$mysqli->query("CREATE TEMPORARY TABLE myCity LIKE City");

/* Prepare an insert statement */
$stmt $mysqli->prepare("INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)");

/* Bind variables to parameters */
$stmt->bind_param("sss"$val1$val2$val3);

$val1 'Stuttgart';
$val2 'DEU';
$val3 'Baden-Wuerttemberg';

/* Execute the statement */
$stmt->execute();

$val1 'Bordeaux';
$val2 'FRA';
$val3 'Aquitaine';

/* Execute the statement */
$stmt->execute();

/* Retrieve all rows from myCity */
$query "SELECT Name, CountryCode, District FROM myCity";
$result $mysqli->query($query);
while (
$row $result->fetch_row()) {
    
printf("%s (%s,%s)\n"$row[0], $row[1], $row[2]);
}

Procedural style

<?php

mysqli_report
(MYSQLI_REPORT_ERROR MYSQLI_REPORT_STRICT);
$link mysqli_connect("localhost""my_user""my_password""world");

mysqli_query($link"CREATE TEMPORARY TABLE myCity LIKE City");

/* Prepare an insert statement */
$stmt mysqli_prepare($link"INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)");

/* Bind variables to parameters */
mysqli_stmt_bind_param($stmt"sss"$val1$val2$val3);

$val1 'Stuttgart';
$val2 'DEU';
$val3 'Baden-Wuerttemberg';

/* Execute the statement */
mysqli_stmt_execute($stmt);

$val1 'Bordeaux';
$val2 'FRA';
$val3 'Aquitaine';

/* Execute the statement */
mysqli_stmt_execute($stmt);

/* Retrieve all rows from myCity */
$query "SELECT Name, CountryCode, District FROM myCity";
$result mysqli_query($link$query);
while (
$row mysqli_fetch_row($result)) {
    
printf("%s (%s,%s)\n"$row[0], $row[1], $row[2]);
}

The above examples will output:

Stuttgart (DEU,Baden-Wuerttemberg)
Bordeaux (FRA,Aquitaine)
