sqlite_column - Fetches a column from the current row of a result set

SYNOPSIS
mixed sqlite_column (resource $result, mixed $index_or_name, [bool $decode_binary = true]) DESCRIPTION
mixed SQLiteResult::column (mixed $index_or_name, [bool $decode_binary = true]) mixed SQLiteUnbuffered::column (mixed $index_or_name, [bool $decode_binary = true]) Fetches the value of a column named $index_or_name (if it is a string), or of the ordinal column numbered $index_or_name (if it is an integer) from the current row of the query result handle $result. PARAMETERS
o $result - The SQLite result resource. This parameter is not required when using the object-oriented method. o $index_or_name - The column index or name to fetch. 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 column value. NOTES
Note Use this function when you are iterating a large result set with many columns, or with columns that contain large amounts of data. SEE ALSO
sqlite_fetch_string(3). PHP Documentation Group SQLITE_COLUMN(3)
