public `bool` `mysqli_stmt::execute` ``array``null```params`&null;

&style.procedural;

`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.

&reftitle.parameters;

&mysqli.stmt.description;

`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;.
