protected function schedule(Schedule $schedule)
{
$schedule->call(function () {
$properties = DB::table( 'properties' )->where( 'status', '=', 1 )->whereNotNull( 'id_client' )->whereNotNull( 'id_period' )->get();
$dates = array();
foreach ($properties as $k => $v) {
$dates[$k] = DB::table( 'periods' )->where( 'id', '=', $v->id_period )->whereDate('date', '>', date('Y-m-d'))->get();
}
$properties_status = array();
/* ----- HERE ---------*/
foreach ($dates as $v) {
Log::info($v);
}
})->everyMinute();
}
You should json_decode($v)
so you can treat it like a struct. 您应该使用
json_decode($v)
以便将其视为结构。 Otherwise it's just a string to you. 否则对您来说只是一个字符串。
This is JSON. 这是JSON。 It's a kind of data format.
这是一种数据格式。 You can decode it in PHP by using:
您可以使用以下方法在PHP中对其进行解码:
$var = json_decode($v, true);
And in $var
you will get a normal array. 在
$var
您将获得一个普通数组。 Which you can simple check with print_r($var);
您可以使用
print_r($var);
简单检查print_r($var);
. 。
