I need to run a given package on both HHVM runtime and traditional PHP runtime. My question: is there a way to check programmatically if current environment is HHVM? Something like this:
<?php
if(running_on_hhvm()) {
// do hhvm compatible routine
}
else {
// do normal routine
}
You can utilise the constant HHVM_VERSION specific to HHVM:
if (defined('HHVM_VERSION')) {
// Code
}
You can put this in your own function if you want.
function is_hhvm() {
return defined('HHVM_VERSION');
}
if (is_hhvm()) {
// Code
}
