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

### Description

Object-oriented style

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

Procedural style

function 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

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)

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');

    /* 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()) {
        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 (?,?,?)');

    /* Execute the statement */
    mysqli_stmt_execute($stmt, ['Stuttgart', 'DEU', 'Baden-Wuerttemberg']);

    /* 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)
