    mysqli_stmt_execute

    (PHP 5, PHP 7, PHP 8)

    mysqli_stmt::execute -- mysqli_stmt_execute — Executes a prepared statement

    Description

    Object-oriented style

    publicmysqli_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.

    Errors/Exceptions

    If mysqli error reporting is enabled (MYSQLI_REPORT_ERROR) and the requested operation fails, a warning is generated. If, in addition, the mode is set to MYSQLI_REPORT_STRICT, a mysqli_sql_exception is thrown instead.

    Changelog

    VersionDescription
    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");


    $stmt = $mysqli->prepare("INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)");


    $stmt->bind_param("sss", $val1, $val2, $val3);

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


    $stmt->execute();

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


    $stmt->execute();


    $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");


    $stmt = mysqli_prepare($link, "INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)");


    mysqli_stmt_bind_param($stmt, "sss", $val1, $val2, $val3);

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


    mysqli_stmt_execute($stmt);

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


    mysqli_stmt_execute($stmt);


    $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 #2 Execute a prepared statement with an array of values

    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');


    $stmt = $mysqli->prepare('INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)');


    $stmt->execute(['Stuttgart', 'DEU', 'Baden-Wuerttemberg']);


    $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');


    $stmt = mysqli_prepare($link, 'INSERT INTO myCity (Name, CountryCode, District) VALUES (?,?,?)');


    mysqli_stmt_execute($stmt, ['Stuttgart', 'DEU', 'Baden-Wuerttemberg']);


    $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]);
    }
