Both commands are used to display some output, so what’s the difference? I chanced upon an interesting article that covers the differences between the two. I’ll put up the summary here:

• echo is (marginally) faster than print. Providing that the statement is in a large enough loop, one will notice a slight performance gain by using echo. It’s probably advisable in the long run, unless you’re already used to print.
• passing mutiple string parameters is faster than concatenating multiple echo calls. See example below:

// "." signals concatenation and is slower
echo "hello" . "world"

// "," signals multiple arguments and is faster
echo "hello", "world"
