sqlite_fetch_array
SQLiteResult->fetch
SQLiteUnbuffered->fetch
(PHP 5, PECL sqlite >= 1.0.0)
sqlite_fetch_array -- SQLiteResult->fetch -- SQLiteUnbuffered->fetch — Fetches the next row from a result set as an array
说明
array sqlite_fetch_array ( resource $result [, int $result_type = SQLITE_BOTH [, bool $decode_binary = true ]] )Object oriented style (method):
array SQLiteResult::fetch ([ int $result_type = SQLITE_BOTH [, bool $decode_binary = true ]] ) array SQLiteUnbuffered::fetch ([ int $result_type = SQLITE_BOTH [, bool $decode_binary = true ]] )Fetches the next row from the given result handle. If there are no more rows, returns FALSE, otherwise returns an associative array representing the row data.
参数
- result
-
The SQLite result resource. This parameter is not required when using the object-oriented method.
- result_type
-
可选的 result_type 参数接受常量，且决定返回的数组如何被索引。使用 SQLITE_ASSOC 会仅返回关联索引（已命名字段），而 SQLITE_NUM 会仅返回数值索引。SQLITE_BOTH 会同时返回关联和数值索引。SQLITE_BOTH 是此函数的默认值。
- decode_binary
-
当 decode_binary 参数设置为 TRUE（默认值）时，PHP 会解码那些由 sqlite_escape_string() 编码后的二进制数据。通常应保留此值为其默认值，除非要与其他使用 SQLlite 的应用程序建立的数据交互。
返回值
Returns an array of the next row from a result set; FALSE if the next position is beyond the final row.
由 SQLITE_ASSOC 与 SQLITE_BOTH 返回的列名会依照 sqlite.assoc_case 配置选项的值决定大小写。
范例
Example #1 Procedural example
<?php
$dbhandle = sqlite_open('sqlitedb');
$query = sqlite_query($dbhandle, 'SELECT name, email FROM users LIMIT 25');
while ($entry = sqlite_fetch_array($query, SQLITE_ASSOC)) {
echo 'Name: ' . $entry['name'] . ' E-mail: ' . $entry['email'];
}
?>
Example #2 Object-oriented example
<?php
$dbhandle = new SQLiteDatabase('sqlitedb');
$query = $dbhandle->query('SELECT name, email FROM users LIMIT 25'); // buffered result set
$query = $dbhandle->unbufferedQuery('SELECT name, email FROM users LIMIT 25'); // unbuffered result set
while ($entry = $query->fetch(SQLITE_ASSOC)) {
echo 'Name: ' . $entry['name'] . ' E-mail: ' . $entry['email'];
}
?>
