Steps to run

I prepared a simple dockerfile that eases the running of PHP code given below

# Use the official PHP image with Apache
FROM php:7.4-apache

# Install git and unzip which might be needed for composer operations
RUN apt-get update && apt-get install -y git unzip

# Install Composer globally
RUN php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" \
    && php composer-setup.php --install-dir=/usr/local/bin --filename=composer \
    && php -r "unlink('composer-setup.php');"

# Set the working directory to the root of your Apache directory
WORKDIR /var/www/html

# Copy your PHP script to the Docker image
COPY . /var/www/html/

# Use Composer to install dependencies
RUN composer install

# Expose port 80 to access the Apache server
EXPOSE 80

# Start Apache in the foreground
CMD ["apache2-foreground"]

• Put this in a folder with a file called script.php and paste the code you want to run in the file
• Create a composer.json file in the same folder with below content

  {
  "require": {
  "php-http/discovery": "^1.14",
  "php-http/guzzle7-adapter": "^1.0",
  "guzzlehttp/psr7": "^2.0",
  "nyholm/psr7": "^1.4",
  "nyholm/psr7-server": "^1.0"
  }
  }

• Put any image in the same folder as well and image can be used in formdata with path ./<filename>
• execute the below command

  docker build -t php-apache-app . && docker run --rm -p 80:80 php-apache-app

• Once the dockerfile is up and running, browse to http://localhost/script.php or run the below curl in separate in terminal to see the output

  curl http://localhost/script.php

@ashitaprasad @animator please review this PR Let me know if you face any difficulties in running the code

Here is a screenshot of the code runs just in case

[animator]

Multipart implementation is bloated and can be heavily simplified. Take a look at https://docs.php-http.org/en/latest/components/multipart-stream-builder.html

[apoorvdwi]

• Made the changes
• Verified the newly generated code
• Updated the tests

@animator let me know if any more changes are required

[animator]

Why are you hardcoding boundary? MultipartStreamBuilder already adds a boundary that can be obtained using

$boundary = $builder->getBoundary();

https://docs.php-http.org/en/latest/components/multipart-stream-builder.html#building-a-multipart-stream

[apoorvdwi]

Yes, we can use that as well or we can pass a custom boundary as well. I was using the later way. I have made the changes to use default boundary from multiparts builder

Thanks for fixing the issue. LGTM 🚀
