SQLITE_FETCH_SINGLE(3)SQLITE_FETCH_SINGLE(3)sqlite_fetch_single - Fetches the first column of a result set as a stringSYNOPSIS
string sqlite_fetch_single (resource $result, [bool $decode_binary = true])
DESCRIPTION
Object oriented style (method):
string SQLiteResult::fetchSingle ([bool $decode_binary = true])
string SQLiteUnbuffered::fetchSingle ([bool $decode_binary = true])
sqlite_fetch_single(3) is identical to sqlite_fetch_array(3) except that it returns the value of the first column of the rowset.
This is the most optimal way to retrieve data when you are only interested in the values from a single column of data.
PARAMETERS
o $result
- The SQLite result resource. This parameter is not required when using the object-oriented method.
o $decode_binary
-When the $decode_binary parameter is set to TRUE (the default), PHP will decode the binary encoding it applied to the data if it
was encoded using the sqlite_escape_string(3). You should normally leave this value at its default, unless you are interoperating
with databases created by other sqlite capable applications.
RETURN VALUES
Returns the first column value, as a string.
EXAMPLES
Example #1
A sqlite_fetch_single(3) example
<?php
if ($dbhandle = sqlite_open('mysqlitedb', 0666, $sqliteerror)) {
$sql = "SELECT id FROM sometable WHERE id = 42";
$res = sqlite_query($dbhandle, $sql);
if (sqlite_num_rows($res) > 0) {
echo sqlite_fetch_single($res); // 42
}
sqlite_close($dbhandle);
}
?>
