Когда я запускаю свой код, появляется сообщение
Неустранимая ошибка: невозможно использовать временное выражение в контексте записи в C: \ xampp \ htdocs \ PA2 \ PracticalAssignment2. php в строке 173
Вот мой код:

Это часть для меня, чтобы сохранить входное значение из таблицы выше в многомерный массив:
<?php
// add item to array and display in text file
$studentsArray = [
'StudentID' => &_POST['id'],
'StudentName' => &_POST['name'],
'SubjectEnglish' => &_POST['eng'],
'SubjectMaths' => &_POST['math'],
'SubjectHistory' => &_POST['his'],
'SubjectSciences' => &_POST['sc'],
'SubjectPhysics' => &_POST['phy'],
'ScoreTotal' => &_POST['total'],
'ScaoreAverage' => &_POST['average']];
$file = 'studentscore.txt';
$fh = fopen($file, 'w') or die("can't open file");
fwrite($fh, print_r($studentsArray,true));
fclose($fh);
?>
