Run PHP CLI from Windows Powershell ISE

Question

This question is regarding dollar signs "$" $ in Windows PowerShell ISE.

I have PHP CLI and want to run one liner command scripts from the prompt in Windows PowerShell ISE.

php -r "$foo = 'foo';"

Just returns Parse error: parse error in Command line code on line 1 and I've narrowed it down to the pesky dollar sign which is significant in PowerShell. Can I escape it somehow?

I also tried

php -r '$foo = "foo";'

and get

Notice: Use of undefined constant foo - assumed 'foo' in Command line code on line 1

Yes, add a backtick in front of the dollar sign:

php -r "`$foo = 'foo';"

Also, I don't know if single-quotes are significant in PHP, but if OP encloses the command in single-quotes (and used double-quotes around foo), then there wouldn't be a need to escape the $ as Powershell interprets anything in single-quotes literally.

This is what you need:

"`$foo = 'foo';"
