Question

I have a function that passes an argument with two default values…

function places($location="Minneapolis", $lodging="Mom's house")
{
    echo "enjoys going to {$location} and staying at {$lodging} while on vacation.";
}
places("St. Paul","Grandma's house");

I need to pass the function 10 times using 10 different names of people defined as a variable passed as an argument. What would the syntax be assuming the output would resemble this:

Joe enjoys going to St. Paul and staying at Grandma’s house while on vacation.

See my comments in the code. You didn’t make the $i iterator a valid PHP variable, so FYI: All PHP variables must be prefixed with a $.

<?php

// You declare your functions typically in the global scope, not
// within a for or any other loop.
// NOTE: $name is a required function parameter in this function.

function places($name, $location="Minneapolis", $lodging="Mom's house") {
    return "$name enjoys going to $location and staying at $lodging while on vacation.";
}

// Note, I've got $people setup to have arrays that can be passed
// containing a "name, city, hotel" syntax. This is equivalent to
//     $people[loop index][0] ~ $people[loop index][name]
//     $people[loop index][1] ~ $people[loop index][city]
//     $people[loop index][2] ~ $people[loop index][hotel]

$people = array(
    array("James", "Brooklyn", "Granada Inn"),
    array("Betsy", "Memphis", "Tennessee Hotel"),
    array("Andrew", "San Francisco", "101 Hotel"),
    array("Marvin", "San Diego", "Oceanview Beach Resort"),
    array("Sara", "Orlando", "Disney World"),
    array("Alicia", "Hilton Head", "Vincent Inn")
);

// Cache the count of the $names array members

$c_people = count($people);

// Loop and echo.

for ($i = 0; $i < $c_people; $i++) {
    echo places($people[$i][0], $people[$i][1], $people[$i][2]) . "\n";
}

?>
