mysqli_stmt::execute -- mysqli_stmt_execute — Executes 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.

### 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

    <?phpmysqli_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

    <?phpmysqli_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

    <?phpmysqli_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

    <?phpmysqli_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)
