I have written this chunk which always fails to open the file. I cannot figure out why
<?php
$file=‘/var/www/html/messages.txt’;
$fp=fopen($file, ‘a+’) or die(“fopen failed);
?>
The code always spits out “fopen failed” and I can’t figure out why. I’m hoping someone can help.
I've created a Christmas tree using only HTML and CSS. It's pretty sure that the code can be written in a more efficient way. Also, the lights are turning on and off at the same time, is there a way to make them work independently?

Currently, I am using a code similar to the following example to create a table with tkinter using Python 3:
Each cell is individually created as a ttk.Label and they're displayed using .grid(row, column)
Some of my values get updated while the program is running with tk.StringVar().set()

I am very sure my code does not follow PEP 8 nor uses any functions whatsoever. I'm here to learn how to improve it exactly by making each action a function. I am also open to other criticism or suggestions.

The previous day, I helped someone build a really simple console "Lucky Number" game. It's really simple, the user has to choose a number, the program will also choose one, and if there's a match between the two, the user wins.
To made the game a bit more visual, the numbers are initially blue an...
In this method, I was tasked to take in a list of TemplateMap and attach dynamic parameters and in a certain case, add further templates to the returned list. This functionality exists within a report rendering service and at this stage, I am constructing the templates to send into the rendering ...

As I am developing my first real API, I encountered that I wrote a lot of serialisers and I think there could be a possibility to merge them together. For example I have this 3 distinct serialisers for different methods:
class PropertySerializer(serializers.ModelSerializer):
class Meta:

So, I have written this class. And it seems valid, https://onlinegdb.com/meN5a_I2I & https://onlinegdb.com/HybpyOO6P.
But, it contains lots of faults apparently.

I have a bean that has around 10+ fields and it may grow till 30 odd fields. The bean is a contract between applications to share data over an HTTP call. Basically, a downstream application will set exactly one field and will make a rest call.

I'm using the Udemy class by Denis Panjuta and followed 8 sections before making my first app by myself.
The 8 sections include Datatypes and Variables, Functions and Methods, Making decisions, Loops, OOP, Arrays and List, ...
I've recently started working on my own game engine and I have been thinking about creating my own model format. Since text usually takes a long time to load and process I decided to make a binary file. After a little work, I already had the basic concept:

I'm trying to implement a function (a template-helper function) which provides a simple merge-like functionality for both arrays and objects. The two functions are basically looks identical:

This code works, and I'm pretty sure it's mathematically/algorithmically correct:

model,
tf.keras.layers.Flatten(),
