複数の配列を並べ替える方法についてサポートが必要です。これは私が得たものです:
Array (
[ALU0000001] =>
Array ( [0] => Array ( [period] => 2012 [codCurse] => S12-2030 [idPersona] => ALU0000001 [date] => 2012-04-02 [amount] => 238.00 [active] => X )
[1] => Array ( [period] => 2012 [codCurse] => S12-2030 [idPersona] => ALU0000001 [date] => 2012-05-02 [amount] => 238.00 [active] => X )
[2] => Array ( [period] => 2012 [codCurso] => S12-2030 [idPersona] => ALU0000001 [date] => 2012-06-02 [amount] => 238.00 [active] => X )
[3] => Array ( [period] => 2013 [codCurso] => S12-2030 [idPersona] => ALU0000001 [date] => 2013-01-02 [amount] => 238.00 [active] => X )
[ALU0000005] =>
Array ( [0] => Array ( [period] => 2013 [codCurse] => S13-2010 [idPersona] => ALU0000005 [date] => 2013-03-01 [amount] => 225.00 [active] => X )
[1] => Array ( [period] => 2013 [codCurse] => S13-2010 [idPersona] => ALU0000005 [date] => 2013-03-02 [amount] => 333.00 [active] => X )
[2] => Array ( [period] => 2013 [codCurse] => S13-2010 [idPersona] => ALU0000005 [date] => 2013-04-02 [amount] => 333.00 [active] => X )
このようなものを取得するには、マルチアレイを期間の日付で並べ替える必要があります
