3v4l.org

About

3v4l.org is an online shell that allows you to run your code on my server. I compiled more than 150 different PHP versions (every version released since 4.3.0) plus HHVM for you to use. For every script you submit, this site tells you:

• Output from all released PHP and HHVM versions
• Performance (time and memory) of every version
• VLD opcode output
• Contextual links to documentation and php sourcecode
• Output from all upcoming alpha, beta & release-candidates
• Output from a few popular RFC Branches
• HHVM Bytecode output

To keep this site running I spend ~ 100 mBTC monthly; want to help out? Donate through Bitcoin. For updates, follow me on Twitter @3v4l_org.

Have fun!
