sqlite_current
SQLiteResult::current
SQLiteUnbuffered::current
(PHP 5 < 5.4.0, PECL sqlite >= 1.0.0)
sqlite_current -- SQLiteResult::current -- SQLiteUnbuffered::current — Fetches the current row from a result set as an array
说明
$result
[, int $result_type = SQLITE_BOTH
[, bool $decode_binary = TRUE
]] ) : array面向对象风格 (method):
$result_type = SQLITE_BOTH
[, bool $decode_binary = TRUE
]] ) : array$result_type = SQLITE_BOTH
[, bool $decode_binary = TRUE
]] ) : arraysqlite_current() is identical to sqlite_fetch_array() except that it does not advance to the next row prior to returning the data; it returns the data from the current position only.
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 current row from a result set; FALSE if the
current 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。
