Answer 1

You could also consider using list(); you'll have to make a slight change to your function but it'll work.
function show(){
$name = "john";
$family = "cina";
$old = "45";
return array($name,$family,$old);
}
list($name,$family,$old) = show();
echo $name;
echo $family;
echo $old;
Be aware that the order matters, the first value in the return array will be assigned to the first variable in the list(); and the second array value to the second variable in the list, and so on.

Answer 2

Write echo inside function as below
function show()
{
$name = "john";
$family = "cina";
$old = "45";
echo $name." ".$family." ".$old;
}
show();

Answer 3

function show()
{
$name = "john";
$family = "cina";
$old = "45";
return $name." ".$family." ".$old;
}
echo show();
This

Answer 4

Return it from your function like this
function show()
{//for e.g
$name = "john";
$family = "cina";
$old = "45";
return $name . " " . $family . " " . $old;
}
$result = show();
echo $result;

Answer 5

you can use also in the following way
function show()
{
$name = "john";
$family = "cina";
$old = "45";
return $name." ".$family." ".$old;
}
echo $res = show(); // john cina 45

Answer 6

This is how I should do it =)
<?php
function show()
{
$name = "john";
$family = "cina";
$old = "45";
echo $name." ".$family." ".$old;
}
show();
?>

Answer 7

As a general rule, don't do this. It's not very good and looks terrible, but this is what you need.
<?php
$name = null;
$family = null;
$old = null;
function show()
{
global $name, $family, $old;
$name = "john";
$family = "cina";
$old = "45";
}
show();
echo "your name is $name ".PHP_EOL;
echo "your family is $family ".PHP_EOL;
echo "your old is $old ".PHP_EOL;
I will recommend an alternative way of writing this (one of many). You can check other answers for different ways.
class Singleton {
public static $name;
public static $family;
public static $old;
}
function show()
{
Singleton::$name = "john";
Singleton::$family = "cina";
Singleton::$old = "45";
}
show();
echo "your name is ".Singleton::$name;//in another line
echo "your family is ".Singleton::$family;//in another line
echo "your old is ".Singleton::$old;//in another line
