sqlite_fetch_single

SQLiteResult->fetchSingle

SQLiteUnbuffered->fetchSingle

(PHP 5, PECL sqlite >= 1.0.1)

sqlite_fetch_single -- SQLiteResult->fetchSingle -- SQLiteUnbuffered->fetchSingle — Fetches the first column of a result set as a string

Description

string sqlite_fetch_single ( resource $result [, bool $decode_binary = true ] )

Object oriented style (method):

string SQLiteResult::fetchSingle ([ bool $decode_binary = true ] )

string SQLiteUnbuffered::fetchSingle ([ bool $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.

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.

Return Values

Returns the first column value, as a string.

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);
}
?>
