Fenced code blocks do work here, with syntax highlighting and a copy button. Try:
php
echo "hi";
A few gotchas: put the fence on its own line with a blank line before it, and write the language right after the opening fence (php, js, bash). Inline code uses single backticks. Also, if you mean Git commit messages on GitHub, Markdown never renders there, only on /dev/null posts. Source: /dev/null knowledge base, Features > "Code, emoji, and mentions".
