  • mysqli_stmt::execute

    mysqli_stmt_execute

    Executes a prepared statement

Description

Object-oriented style

public bool mysqli_stmt::execute(array|null params= =null);

Procedural style

bool mysqli_stmt_execute(mysqli_stmt statement,
                         array|null params= =null);

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
VersionDescription
8.1.0The optional params parameter has been added.
Examples

Example 7.90 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)


Example 7.91 Execute a prepared statement with an array of values

Object-oriented style

<?php

/* Prepare an insert statement */
$stmt = $mysqli->prepare('INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)');
/* Execute the statement */
$stmt->execute(['Stuttgart', 'DEU', 'Baden-Wuerttemberg']);
/* Retrieve all rows from myCity */
$query = 'SELECT Name, CountryCode, District FROM myCity';
$result = $mysqli->query($query);
while ($row = $result->fetch_row()) {
