PHP/Sqlite3：致命錯誤：調用未定義的函數sqlite_num_rows（）

Question

當我調用函數sqlite_num_rows時出現此錯誤。它不能是依賴性問題，因爲其他Sqlite函數正在工作。我可以打開連接並從數據庫中獲取數據。

Answer 1

相對於信息上php.net

neither of "sqlite_num_rows($result)" and "$result->numRows()" is not working on SQLite3 ! you should use this way:

<?php 
$db = new SQLite3('databasename.db'); 
$result = $db->query("SELECT * FROM users"); 
$rows = count ($result); 
echo "Number of rows: $rows";
