如何解决致命错误“在865行的/xyz/pqr/prj_name/functions/common.php中对非对象调用成员函数格式（）”？

问题描述：

Following is the necessary code from file "/xyz/pqr/prj_name/functions/common.php"

function format_date_yyyy_mm_dd($date_val) {
  $date = DateTime::createFromFormat('n-j-Y', $date_val);
  return $date->format('Y-m-d');  //Thie is line no.865 where I'm getting the error.
}

This file has been included into the file where the function format_date_yyyy_mm_dd() is called.

The code for calling the function is as follows :

$form_data['reg_date'] = format_date_yyyy_mm_dd($form_data['reg_date']);

Can some one please help in correcting the code I've written and help me where my code is going wrong?

Thanks in advance.

以下是文件“/xyz/pqr/prj_name/functions/common.php “ p>

  function format_date_yyyy_mm_dd（$ date_val）{
 $ date = DateTime :: createFromFormat（'nj-Y'，$ date_val）; 
返回$ date  - ＆GT;格式（ 'YM-d'）;  //这是第865行，我收到错误。
} 
  code>  pre> 
 
 此文件已包含在函数的文件中 调用format_date_yyyy_mm_dd（） code>。 p> 
 
 
调用该函数的代码如下： p> 
 
 

  $ form_data ['reg_date  '] = format_date_yyyy_mm_dd（$ form_data ['reg_date']）; 
  code>  pre> 
 
 有人可以帮助纠正我编写的代码并帮助我在哪里编写代码 出错了？ p> 
 
 
提前致谢。 p>

答

You code is correct, please check the value of $form_data['reg_date'] and make sure it is something like 12-19-2014 and it should be month-date-year. You may passing wrong format of date from your form.

echo format_date_yyyy_mm_dd('12-19-2014');
