This works as follows:
First read the char sent by server till next line
Now flush the server
Now write your content to the server.

I'm trying to stream voice to the MQTT broker. I'm using esp8266(NodeMCU1.0) and it's ADC to sampling the audio signal at 4KHz and 8-bit PCM audio format. I used Pubsubclient.h library to publish audio packets to the broker but on the other side when I receive packets and play them I have the interrupted voice and I have a delay between playing packets as long as my buffer size. please help me to have continues voice.
I have 2 main problems:
1) delay between playing packets as long as my buffer size

2) Quality of voice: I receive a noisy voice.

I am not able to receive my values to loop function due to the wrong implementation of the function.
I need your suggestion to make this kind of solution or any different way which will be useful to make a callback function.
On Arduino it is typical to use global variables for things. You'll be having hard time trying to fight with that.
If you want to get multiple values read from your function, you could define a struct that packs those values, and pass a pointer to that struct as an output parameter, and fill it in your function.
I don't believe that Arduino has callbacks out of the box, but you might implement an event loop yourself.
I'm trying to get data from a txt file through my website to turn the LED on or off, the connection to the website works and the data from a txt file is printed on the serial as the code shows, but on the loop condition when I read a txt file with '1' it should light on the LED, but that does not work

Instead of a POST command, try using a GET request.
Change POST project/add.php to GET /project/add.php?
I am currently involved in a project which needs to have 4 led's and one stepper motor to be turned on/off independently over wifi.
Just to mention Im using an Uno r3, official Wifi shield and official motor shield.
I have the 4 led's working on pins A2-A5 or in my code pins (16-19) leaving free all digital pins and have set up my stepper motor to pins 9,8,6,5. When i go to the ip address i can turn off/on each LED independently but with the stepper motor it either judders and does not move or nothing at all.
I have posted my code so far below, would really appreciate any help or advice. Thanks
/*
WiFi Web Server LED Blink
A simple web server that lets you blink an LED via the web.
This sketch will print the IP address of your WiFi Shield (once connected)
to the Serial monitor. From there, you can open that address in a web browser
to turn on and off the LED on pin 9.
This example is written for a network using WPA encryption. For
WEP or WPA, change the Wifi.begin() call accordingly.
