This actually is a pretty old short note and was brought from: http://salearningschool.com/displayArticle.php?table=Articles&articleID=1357&title=PHP%20Security%20-%20Guidelines

• Do not store sensitive information in Cookies
• Instead of cookies, store sensitive information in Sessions
• Sessions can also be hacked though safer than cookies
• PHP session id is pretty random; so in general this is not a problem.
• Reducing the session security problem: determine current user is the one who originally initiated session. if not, deny access
• Regenerate session ids after login, on initialization
• Change the session variable name and the path to save [session_save_path(), session_name (“xyz”) ]
• Reduce session runtime [session.gc_maxlifetime]
• use SSL [force users to use SSL]
• do not use .inc files and do not keep php code inside them
• Do not use dynamic file path for require and include
• Do not use relative file path [use absolute file path]
• Do not trust user input to prevent XSS
• use htmlspecialchars(). strip_tags(), htmlentities() on the user input
• To prevent Cross-site Request Forgeries (CSRF), check $_SERVER [‘HTTP_REFERER’]
• You may want to use token in your session to prevent CSRF. Re-authenticate for sensitive operations
• When you use third party tools, do not install them in their default loation
• When error situation occurs in your code, just stop
• Use authorization to allow a user the minimal right he/she needs
• Double check where you are using eval()
• use mysql_real_escape_string() on the user provided data to be used in Databasequeries
• Use prepared statements or stored procedures
• Double verify the data types. do not accept string where the data has to be integer [ctype_digit()., filter_var() do not use is_int() and is_numeric()]
• Keep log files and check your log files time to time
• do not display detail error messages in your live site. But you can log the erros for your own checking
• do not use standard login names such as administrator, root
• do not put your administration module under folder named admin
• You can even use a different file extension other than .php [but not .inc]
• Stop spamming using your contact form. Validate email address. use filter_var()
• encrypt sensitive information
• initialize variables when first declared
• Disable register_globals in php.ini
• do not use $_REQUEST, instead use $_GET and $_POST
• When developing use E_ALL to know all the possible errors. but turn off E_ALL in live site
• Type Cast and verify data. Only allow the appropriate data type
• use ctype_alnum(), ctype_alpha(), ctype_xdigit()
• Use htmlspecialchars() and htmlentities() more than using strip_tags()
• SQL escaping (to prevent SQL Injection): mysql_escape_string(), mysql_real_escape_string(), pg_escape_string(), pg_escape_bytea(), sqlite_escape_string()
• to avoid double escaping use get_magic_quotes_gpc()
• Session security technique: compare with the browser signature headers. if no match, destroy the session.
• for shared hosting use the following two php.ini directives properly: open_basedir, safe_mode

“Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and trivial to integrate with web services.”

http://docs.guzzlephp.org/en/latest/index.html
And from my .bash_history, the installation process

curl -sS https://getcomposer.org/installer | php
php composer.phar require guzzlehttp/guzzle:~6.0

To Contribute to Guzzle:
git clone https://github.com/guzzle/guzzle.git
cd guzzle && curl -s http://getcomposer.org/installer | php && ./composer.phar install –dev
make test
sudo make test
node
sudo node
brew install node
node -v
brew update
make test

—
and you can write a simple PHP script as below to access Github
I tried the code as below with real Github user accounts and the code works.

request(‘GET’, ‘https://api.github.com/user’, [
‘auth’ => [‘user-name’, ‘password’]
]);
echo $res->getStatusCode();
// “200”
echo $res->getHeader(‘content-type’);
// ‘application/json; charset=utf8′
echo $res->getBody();
// {“type”:”User”…’

// Send an asynchronous request.
$request = new GuzzleHttpPsr7Request(‘GET’, ‘http://httpbin.org’);
$promise = $client->sendAsync($request)->then(function ($response) {
echo ‘I completed! ‘ . $response->getBody();
});
$promise->wait();
