Object oriented style
Procedural style
Executes one or multiple queries which are concatenated by a semicolon.
To retrieve the resultset from the first query you can use mysqli_use_result() or mysqli_store_result(). All subsequent query results can be processed using mysqli_more_results() and mysqli_next_result().
Procedural style only: A link identifier returned by mysqli_connect() or mysqli_init()
The query, as a string.
Data inside the query should be properly escaped.
Returns FALSE
if the first statement failed. To retrieve subsequent errors from other statements you have to call mysqli_next_result() first.
Object oriented style
<?php $mysqli = new mysqli("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $query = "SELECT CURRENT_USER();"; $query .= "SELECT Name FROM City ORDER BY ID LIMIT 20, 5"; /* execute multi query */ if ($mysqli->multi_query($query)) { do { /* store first result set */ if ($result = $mysqli->store_result()) { while ($row = $result->fetch_row()) { printf("%s\n", $row[0]); } $result->free(); } /* print divider */ if ($mysqli->more_results()) { printf("-----------------\n"); } } while ($mysqli->next_result()); } /* close connection */ $mysqli->close(); ?>
Procedural style
<?php $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $query = "SELECT CURRENT_USER();"; $query .= "SELECT Name FROM City ORDER BY ID LIMIT 20, 5"; /* execute multi query */ if (mysqli_multi_query($link, $query)) { do { /* store first result set */ if ($result = mysqli_store_result($link)) { while ($row = mysqli_fetch_row($result)) { printf("%s\n", $row[0]); } mysqli_free_result($result); } /* print divider */ if (mysqli_more_results($link)) { printf("-----------------\n"); } } while (mysqli_next_result($link)); } /* close connection */ mysqli_close($link); ?>
