File Permission Error on File Move Operation

HELP PLEASE The error indicates that the move_uploaded_file() function failed to transfer a file from a temporary PHP directory to the target directory because it lacked the necessary write permissions. The operation was attempted in the MatriculaController.php script on line 391 and resulted in an inability to move the file, leading to an error message. ERROR Warning: move_uploaded_file(/fotos/1002.jpg): Failed to open stream: Permission denied in /app/controllers/MatriculaController.php on line 391 Warning: move_uploaded_file(): Unable to move '/tmp/php2Bukm2g' to './fotos/1002.jpg' in /app/controllers/MatriculaController.php on line 391 Error al mover el archivo.
