only return means in php code example

Example 1: return two variables php

function getXYZ()
{
    return array(4,5,6);
}

list($x,$y,$z) = getXYZ();

// Afterwards: $x == 4 && $y == 5 && $z == 6
// (This will hold for all samples unless otherwise noted)

Example 2: what is carriage return in php

// "\r" is known as carriage return
Typically on Windows, when you need to represent a line terminator use: "\r\n"
whereas on Unix systems, "\n" is enough.
