Example #1 Object-oriented style
<?phpmysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);$mysqli = new mysqli("localhost", "my_user", "my_password", "world");$code = 'FR';$stmt = $mysqli->prepare("SELECT Name FROM Country WHERE Code=?");$stmt->bind_param('s', $code);$stmt->execute();$row = $stmt->get_result()->fetch_row();for ($i = 0; $i < $stmt->field_count; $i++) { printf("Value of column number %d is %s", $i, $row[$i]);}
Example #2 Procedural style
<?phpmysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);$mysqli = mysqli_connect("localhost", "my_user", "my_password", "world");$code = 'FR';$stmt = mysqli_prepare($mysqli, "SELECT Name FROM Country WHERE Code=?");mysqli_stmt_bind_param($stmt, 's', $code);mysqli_stmt_execute($stmt);$result = mysqli_stmt_get_result($stmt);$row = mysqli_fetch_row($result);for ($i = 0; $i < mysqli_stmt_field_count($stmt); $i++) { printf("Value of column number %d is %s", $i, $row[$i]);}
The above examples will output something similar to:
Value of column number 0 is France
