Коментарии
neither of "sqlite_num_rows($result)" and "$result->numRows()" is not working on SQLite3 !
you should use this way:
$db = new SQLite3('databasename.db');
$result = $db->query("SELECT * FROM users");
$rows = count ($result);
echo "Number of rows: $rows";
@rezaamya
$db = new SQLite3('databasename.db');
$result = $db->query("SELECT * FROM users");
$rows = count ($result);
echo "Number of rows: $rows";
$rows value should always be 1
... even if the query is invalid
I tested that on
SQLite Library 3.7.7.1
//I don't know about you. But for me this is what I had to do
$db = new SQLite3('databasename.db');
$result = $db->query("SELECT * FROM table_name");
$number_of_rows = 0;//for now
while($row = $result->fetchArray()) {
$number_of_rows += 1;
}
echo "Number of rows: $number_of_rows";
