sqlite_fetch_single
(PHP 5) sqlite_fetch_single (no version information, might be only in CVS) SQLiteResult->fetchSingle (no version information, might be only in CVS) SQLiteUnbuffered->fetchSingle -- Fetches the first column of a result set as a string Descriptionstring sqlite_fetch_single ( resource result [, bool decode_binary] ) Object oriented style (method): class SQLiteResult { string fetchSingle ( [bool decode_binary] ) }class SQLiteUnbuffered { string fetchSingle ( [bool decode_binary] ) }
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.
Parameters
- 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.
Examples
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);
}
?>
