sqlite_array_query
SQLiteDatabase->arrayQuery
(PHP 5, PECL sqlite:1.0-1.0.3)
sqlite_array_query -- SQLiteDatabase->arrayQuery — Execute a query against a given database and returns an array
Description
array sqlite_array_query
( resource $dbhandle
, string $query
[, int $result_type
[, bool $decode_binary
]] )
array sqlite_array_query
( string $query
, resource $dbhandle
[, int $result_type
[, bool $decode_binary
]] )
SQLiteDatabase
array arrayQuery
( string $query
[, int $result_type
[, bool $decode_binary
]] )
sqlite_array_query() executes the given query and returns
an array of the entire result set. It is similar to calling
sqlite_query() and then sqlite_fetch_array()
for each row in the result set. sqlite_array_query() is
significantly faster than the aforementioned.
Tip
sqlite_array_query() is best suited to queries
returning 45 rows or less. If you have more data than that, it is
recommended that you write your scripts to use
sqlite_unbuffered_query() instead for more optimal
performance.
Parameters
-
query
-
The query to be executed.
-
dbhandle
-
The SQLite Database resource; returned from sqlite_open()
when used procedurally. This parameter is not required
when using the object-oriented method.
-
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.
-
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(). You should normally leave this
value at its default, unless you are interoperating with databases created by
other sqlite capable applications.
Note: Two alternative syntaxes are
supported for compatibility with other database extensions (such as MySQL).
The preferred form is the first, where the dbhandle
parameter is the first parameter to the function.
Return Values
Returns an array of the entire result set; FALSE otherwise.
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 style
<?php
$dbhandle = sqlite_open('sqlitedb');
$result = sqlite_array_query($dbhandle, 'SELECT name, email FROM users LIMIT 25', SQLITE_ASSOC);
foreach ($result as $entry) {
echo 'Name: ' . $entry['name'] . ' E-mail: ' . $entry['email'];
}
?>
Example #2 Object-oriented style
<?php
$dbhandle = new SQLiteDatabase('sqlitedb');
$result = $dbhandle->arrayQuery('SELECT name, email FROM users LIMIT 25', SQLITE_ASSOC);
foreach ($result as $entry) {
echo 'Name: ' . $entry['name'] . ' E-mail: ' . $entry['email'];
}
?>
