SQLiteDatabase->arrayQuery — Execute a query against a given database and returns an array
說明
Object oriented style (method):
sqlite_array_query() executes the given query and returns an array of the entire result set. It is similar to calling sqlite_query() and then sqlite_fetch_array() for each row in the result set. sqlite_array_query() is significantly faster than the aforementioned.
sqlite_array_query() is best suited to queries returning 45 rows or less. If you have more data than that, it is recommended that you write your scripts to use sqlite_unbuffered_query() instead for more optimal performance.
參數
- query
-
The query to be executed.
- dbhandle
-
The SQLite Database resource; returned from sqlite_open() when used procedurally. This parameter is not required when using the object-oriented method.
- result_type
-
可選的 result_type 參數接受一個常數並決定回傳的陣列如何索引。用 SQLITE_ASSOC 只會回傳關聯索引（有名稱欄位）而 SQLITE_NUM 只會回傳數字索引（有序欄位數）。SQLITE_BOTH 會同時回傳關聯和數字索引。 SQLITE_BOTH 是本函式的預設值。
- decode_binary
-
當 decode_binary 參數設為 TRUE（預設值）時，PHP 將解碼那些由 sqlite_escape_string() 編碼的資料。通常應保留此值為其預設值，除非在操作其它支援 sqlite 程式建立的資料庫時。
Note: 為相容其它資料庫（例如 MySQL），支援另兩種替代的語法。推薦用第一種，dbhandle 參數作為函式的第一個參數。
Return值
Returns an array of the entire result set; FALSE otherwise.
由 SQLITE_ASSOC 和 SQLITE_BOTH 回傳的欄名會根據 sqlite.assoc_case 設定選項的值來決定大小寫。
範例
Example#1 Procedural style
<?php
$dbhandle = sqlite_open('sqlitedb');
$result = sqlite_array_query($dbhandle, 'SELECT name, email FROM users LIMIT 25', SQLITE_ASSOC);
foreach ($result as $entry) {
echo 'Name: ' . $entry['name'] . ' E-mail: ' . $entry['email'];
}
?>
Example#2 Object-oriented style
<?php
$dbhandle = new SQLiteDatabase('sqlitedb');
$result = $dbhandle->arrayQuery('SELECT name, email FROM users LIMIT 25', SQLITE_ASSOC);
foreach ($result as $entry) {
echo 'Name: ' . $entry['name'] . ' E-mail: ' . $entry['email'];
}
?>
