Perch Redirect New Window / Tab

Unfortunately not, php is server side language so doesn't have the capability to do this.

You would need to use JS to do this, something like window.open("https://openinnewtab.com"); would work

However you do it, make sure that you use rel="noopener noreferrer" on any such links for security reasons. See https://web.dev/external-anchors-use-rel-noopener/
