sqlite_array_query
SQLiteDatabase::arrayQuery
(PHP 5 < 5.4.0, PECL sqlite >= 1.0.0)
sqlite_array_query -- SQLiteDatabase::arrayQuery — Execute a query against a given database and returns an array
说明
sqlite_array_query
( resource $dbhandle
, string $query
[, int $result_type = SQLITE_BOTH
[, bool $decode_binary = TRUE
]] ) : array
sqlite_array_query
( string $query
, resource $dbhandle
[, int $result_type = SQLITE_BOTH
[, bool $decode_binary = TRUE
]] ) : array
public SQLiteDatabase::arrayQuery
( string $query
[, int $result_type = SQLITE_BOTH
[, bool $decode_binary = TRUE
]] ) : array
Tip
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.
参数
-
query
-
The query to be executed.
Data inside the query should be properly escaped.
-
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。
Note: 为兼容其他数据库扩展(比如 MySQL)，支持两种可替代的语法。推荐第一种格式，函数的第一个参数是dbhandle。
返回值
Returns an array of the entire result set; FALSE otherwise.
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 过程化风格
<?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'];
}
?>
