sqlite_fetch_all
SQLiteResult::fetchAll
SQLiteUnbuffered::fetchAll
(PHP 5 < 5.4.0, PECL sqlite >= 1.0.0)
sqlite_fetch_all -- SQLiteResult::fetchAll -- SQLiteUnbuffered::fetchAll — Fetches all rows from a result set as an array of arrays
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 ]] ) :
array
sqlite_fetch_all() returns an array of the entire result set from the result resource. It is similar to calling sqlite_query() (or sqlite_unbuffered_query()) and then sqlite_fetch_array() for each row in the result set.
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 remaining rows in a result set. If called right after sqlite_query(), it returns all rows. If called after sqlite_fetch_array(), it returns the rest. If there are no rows in a result set, it returns an empty array.
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');
$result = sqlite_fetch_all($query, SQLITE_ASSOC);
foreach ($result as $entry) {
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
$result = $query->fetchAll(SQLITE_ASSOC);
foreach ($result as $entry) {
echo 'Name: ' . $entry['name'] . ' E-mail: ' . $entry['email'];
}
?>
