mysqli_stmt_result_metadata stmt->result_metadata() Returns result set metadata from a prepared statement &reftitle.description; Procedural style: mysqli_resultmysqli_stmt_result_metadata mysqli_stmtstmt Object oriented style (method): mysqli_stmt mysqli_resultresult_metadata If a statement passed to mysqli_prepare is one that produces a result set, mysqli_stmt_result_metadata returns the result object that can be used to process the meta information such as total number of fields and individual field information. This result set pointer can be passed as an argument to any of the field-based functions that process result set metadata, such as: mysqli_num_fields mysqli_fetch_field mysqli_fetch_field_direct mysqli_fetch_fields mysqli_field_count mysqli_field_seek mysqli_field_tell mysqli_free_result The result set structure should be freed when you are done with it, which you can do by passing it to mysqli_free_result The result set returned by mysqli_stmt_result_metadata contains only metadata. It does not contain any row results. The rows are obtained by using the statement handle with mysqli_stmt_fetch. &reftitle.parameters; &mysqli.stmt.description; &reftitle.returnvalues; Returns a result object or &false; if an error occured. &reftitle.examples; query("DROP TABLE IF EXISTS friends"); $mysqli->query("CREATE TABLE friends (id int, name varchar(20))"); $mysqli->query("INSERT INTO friends VALUES (1,'Hartmut'), (2, 'Ulf')"); $stmt = $mysqli->prepare("SELECT id, name FROM friends"); $stmt->execute(); /* get resultset for metadata */ $result = $stmt->result_metadata(); /* retrieve field information from metadata result set */ $field = $result->fetch_field(); printf("Fieldname: %s\n", $field->name); /* close resultset */ $result->close(); /* close connection */ $mysqli->close(); ?> ]]> name); /* close resultset */ mysqli_free_result($result); /* close connection */ mysqli_close($link); ?> ]]> &reftitle.seealso; mysqli_prepare mysqli_free_result
