如何讓PHP

如何獲取數組數據到foreach循環在PHP

時遇到的代碼如下

$years = $this->report_model->get_year(); 
      print_r($years); 

時上午印刷正在逐漸爲

數組數據到foreach循環

Array ([0] => stdClass Object ([financial_year] => 1972-1973) [1] => stdClass Object ([financial_year] => 1973-1974) [2] => stdClass Object ([financial_year] => 1974-1975) [3] => stdClass Object ([financial_year] => 1975-1976) [4] => stdClass Object ([financial_year] => 1976-1977) [5] => stdClass Object ([financial_year] => 1977-1978) [6] => stdClass Object ([financial_year] => 1978-1979) 

，當我在foreach循環是給作爲

  foreach ($years as $year) { 
      $data['result_data'][] = $this->report_model->get_historical_data($year); 
     } 

我得到的php誤差

A PHP Error was encountered 

Severity: 4096 

Message: Object of class stdClass could not be converted to string 

Filename: database/DB_active_rec.php 

Line Number: 42 

究竟是什麼錯誤我在這裏做

Answer 1

更改此$this->report_model->get_historical_data($year);

對此

$this->report_model->get_historical_data($year->financial_year);

Answer 2

試試這個

foreach ($years as $year) { 
      $data['result_data'][] = $this->report_model->get_historical_data($year->financial_year); 
     } 

Answer 3

只有集合是陣列

的一部分嘗試是這樣的：

foreach (array $years as $key => $object) { 
    echo $object->financial_year; 
}
