Problem

I have two Github accounts: oanhnn (personal) and superman (for work). I want to use both accounts on same computer (without typing password everytime, when doing git push or pull).

Solution

Use ssh keys and define host aliases in ssh config file (each alias for an account).

How to?

Generate ssh key pairs for accounts and add them to GitHub accounts.

Since PHP 7.2 is not supported anymore, it's got delisted from the Hombrew core repository.

You've to find a third-party repository that still contains an older PHP version, such as the shivammathur/php repository.

You need to tap the repository like this in your Homebrew:

brew tap shivammathur/php

	## Pre-requisite: You have to know your last commit message from your deleted branch.
	git reflog
	# Search for message in the list
	# a901eda HEAD@{18}: commit: <last commit message>

	# Now you have two options, either checkout revision or HEAD
	git checkout a901eda
	# Or
	git checkout HEAD@{18}

	<?php

	$url = "https://www.google.com/";
	$curlObj = curl_init();

	curl_setopt($curlObj, CURLOPT_URL, $url);
	curl_setopt($curlObj, CURLOPT_RETURNTRANSFER, 1);
	curl_setopt($curlObj, CURLOPT_HEADER, 1); // must set this line
	curl_setopt($curlObj, CURLOPT_SSL_VERIFYPEER, false);
	$result = curl_exec($curlObj);
