The usage of sqlite_fetch_all should be your choise
(instead the well known practice of "while()" loop)
when unmodified tabledata is prefered.
Example code for a better illustration:
<?php
if ($dbhandle = sqlite_open('mysqlitedb', 0666, $sqliteerror)):
$query = "SELECT x, y FROM sometable LIMIT 3;";
$result = sqlite_query($dbhandle, $query);
// usage with sqlite_fetch_all
$array1 = sqlite_fetch_all($result, SQLITE_ASSOC);
// the "well known practice"
$i = '0';
while ($row = sqlite_fetch_array($result, SQLITE_ASSOC)):
$array2["$i"] = $row;
$i++;
endwhile;
sqlite_close($dbhandle);
endif;
?>
There are no differents within the values of array1 and array2.
Both arrays will be something like:
Array
(
[0] => Array
(
[x] => 22004
[y] => example_data1
)
[1] => Array
(
[x] => 92044
[y] => example_data2
)
[2] => Array
(
[x] => 143060
[y] => example_data3
)
)

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
설명
array sqlite_fetch_all
( resource
$result
[, int $result_type = SQLITE_BOTH
[, bool $decode_binary = true
]] )객체 기반 형식 (method):
array SQLiteResult::fetchAll
([ int
$result_type = SQLITE_BOTH
[, bool $decode_binary = true
]] )
array SQLiteUnbuffered::fetchAll
([ int
$result_type = SQLITE_BOTH
[, bool $decode_binary = true
]] )
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.
인수
-
result -
The SQLite result resource. This parameter is not required when using the object-oriented method.
-
result_type -
선택적인
result_type인수는 반환하는 배열이 어떤 형식일지에 대한 대한 상수를 받습니다.SQLITE_ASSOC를 사용하면 연상배열(이름 필드)로 반환합니다.SQLITE_NUM은 수치배열(순차적인 필드 번호)를 반환합니다.SQLITE_BOTH는 연상 및 수치를 동시에 반환합니다.SQLITE_BOTH가 기본값입니다. -
decode_binary -
decode_binary인수가TRUE(기본값)로 설정되면, PHP는 sqlite_escape_string()를 사용하여 인코드한 데이터로 취급하여 이진 인코딩을 해제합니다. 다른 sqlite 적용 프로그램에서 생성한 데이터베이스를 사용하지 않는 한, 기본값으로 사용하면 됩니다.
반환값
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.
SQLITE_ASSOC와
SQLITE_BOTH로 반환한 열 이름은 sqlite.assoc_case 설정 옵션에 따라서
대소문자가 변환됩니다.
예제
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'];
}
?>
