sqlite_fetch_all
[Editor's note: to get short column names there's an undocumented PRAGMA setting. You can exec "PRAGMA short_column_names = ON" to force that behavior.]
I noticed that if you use Joins in SQL queries, the field name is messed up with the dot!
for example if you have this query:
SELECT n.*, m.nickname FROM news AS n, members AS m WHERE n.memberID = m.id;
now if you want to print_r the results returned using SQLITE_ASSOC type, the result array is like this :
array
(
[n.memberID] => 2
[n.title] => test title
[m.nickname] => NeverMind
[tablename.fieldname] => value
)
and I think it looks horriable to use the variable ,for example, $news['m.nickname'] I just don't like it!
so I've made a small function that will remove the table name (or its Alias) and will return the array after its index is cleaned
<?php
function CleanName($array)
{
foreach ($array as $key => $value) {
//if you want to keep the old element with its key remove the following line
unset($array[$key]);
//now we clean the key from the dot and tablename (alise) and set the new element
$key = substr($key, strpos($key, '.')+1);
$array[$key] = $value;
}
return $array;
}
?>
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
Descrierea
array sqlite_fetch_array
( resource $result
[, int $result_type = SQLITE_BOTH
[, bool $decode_binary = true
]] )
Object oriented style (method):
SQLiteResult
array fetch
([ int $result_type = SQLITE_BOTH
[, bool $decode_binary = true
]] )
SQLiteUnbuffered
array 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.
Parametri
- result
-
The SQLite result resource. This parameter is not required when using the object-oriented method.
- result_type
-
Parametrul opţional result_type acceptă o constantă şi determină cum tablouul întors va fi indexat. Utilizând SQLITE_ASSOC vor fi întorşi numai indici asociativi (câmpuri denumite) în timp ce cu SQLITE_NUM vor fi întorşi numai indici numerici (numerele de ordine ale câmpurilor). Cu SQLITE_BOTH vor fi întorşi atât indici associativi, cât şi numerici. SQLITE_BOTH este valoarea implicită pentru această funcţie.
- decode_binary
-
Când parametrul decode_binary este stabilit în TRUE (implicit), PHP va decodifica codificarea binară pe care a aplicat-o asupra datelor, dacă acestea au fost codificate cu sqlite_escape_string(). În mod normal ar trebui să lăsaţi valoarea implicită, dacă nu interoperaţi cu baze de date create de alte aplicaţii capabile să lucreze cu sqlite.
Valorile întroarse
Returns an array of the next row from a result set; FALSE if the next position is beyond the final row.
În denumirile coloanelor întoarse de SQLITE_ASSOC şi SQLITE_BOTH vor fi utilizate litere majuscule/minuscule în corespundere cu valoarea opţiunii de configurare sqlite.assoc_case.
Exemple
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'];
}
?>
