Can I echo multiple numbers?

I wanted to echo "Hello" from my variable $greeting, but I don't know the syntax $greeting = "Hello, Friends!";

My experiments: echo $greeting{0+1+2+3+4}; echo $greeting{0,1,2,3,4};

I am not sure what you are attempting to accomplish and the structure of your variable. It is an array? If so, you could manually enter the array index like this:

<?php
echo $greeting[0];
echo $greeting[1];
//etc

Note, the above example would put them all on the same line with no space between.

Or if you want them all, this would likely be a better solution:

<?php
foreach ($greeting as $greet) {
    echo $greet;
}

I can tailor my response with some more information.

Thank you for answering!

How do I get a space in between?

If you want just spaces, you add the space in the echo like this: echo $array[0] . ' '; or like this echo "$array[0] "; or add a space to the echo in the foreach loop. If you want it on a new line, I recommend using an html break tag.
