sqlite_fetch_array
SQLiteResult::fetch
SQLiteUnbuffered::fetch
(PHP 5 < 5.4.0, PECL sqlite >= 1.0.0)
sqlite_fetch_array -- SQLiteResult::fetch -- SQLiteUnbuffered::fetch — Fetches the next row from a result set as an array
Description
$result
[, int $result_type = SQLITE_BOTH
[, bool $decode_binary = true
]] )Object oriented style (method):
$result_type = SQLITE_BOTH
[, bool $decode_binary = true
]] )$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.
Parameters
-
result -
The SQLite result resource. This parameter is not required when using the object-oriented method.
-
result_type -
The optional
result_typeparameter accepts a constant and determines how the returned array will be indexed. UsingSQLITE_ASSOCwill return only associative indices (named fields) whileSQLITE_NUMwill return only numerical indices (ordinal field numbers).SQLITE_BOTHwill return both associative and numerical indices.SQLITE_BOTHis the default for this function. -
decode_binary -
When the
decode_binaryparameter is set toTRUE(the default), PHP will decode the binary encoding it applied to the data if it was encoded using the sqlite_escape_string(). You should normally leave this value at its default, unless you are interoperating with databases created by other sqlite capable applications.
Return Values
Returns an array of the next row from a result set; FALSE if the
next position is beyond the final row.
The column names returned by
SQLITE_ASSOC and SQLITE_BOTH will be
case-folded according to the value of the
sqlite.assoc_case configuration
option.
Examples
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'];
}
?>

[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;
}
?>
