LEARN ABOUT PHP
sqlite_fetch_all
SQLITE_FETCH_ALL(3) SQLITE_FETCH_ALL(3)
sqlite_fetch_all - Fetches all rows from a result set as an array of arrays
SYNOPSIS
array sqlite_fetch_all (resource $result, [int $result_type = SQLITE_BOTH], [bool $decode_binary = true])
DESCRIPTION
Object oriented style (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(3) returns an array of the entire result set from the $result resource. It is similar to calling sqlite_query(3) (or
sqlite_unbuffered_query(3)) and then sqlite_fetch_array(3) for each row in the result set.
PARAMETERS
o $result
- The SQLite result resource. This parameter is not required when using the object-oriented method.
o $result_type
-The optional $result_type parameter accepts a constant and determines how the returned array will be indexed. Using SQLITE_ASSOC
will return only associative indices (named fields) while SQLITE_NUM will return only numerical indices (ordinal field numbers).
SQLITE_BOTH will return both associative and numerical indices. SQLITE_BOTH is the default for this function.
o $decode_binary
-When the $decode_binary parameter is set to TRUE (the default), PHP will decode the binary encoding it applied to the data if it
was encoded using the sqlite_escape_string(3). 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 remaining rows in a result set. If called right after sqlite_query(3), it returns all rows. If called after
sqlite_fetch_array(3), it returns the rest. If there are no rows in a result set, it returns an empty array.
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');
$result = sqlite_fetch_all($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'];
}
?>
