(PHP 5 < 5.4.0, PECL sqlite >= 1.0.1)
sqlite_fetch_single -- SQLiteResult::fetchSingle -- SQLiteUnbuffered::fetchSingle — Fetches the first column of a result set as a string
$result
[, bool $decode_binary = true
] )Object oriented style (method):
$decode_binary = true
] )$decode_binary = true
] )sqlite_fetch_single() is identical to sqlite_fetch_array() 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.
result
The SQLite result resource. This parameter is not required when using the object-oriented method.
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.
Returns the first column value, as a string.
Example #1 A sqlite_fetch_single() 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);
}
?>
