Question

The strings $test1, $test2, $test3, and $test4 are created in the function test() . How can I print her?

My code:

conf.php

<?php
function test(){
    $test1 = 'test1 string';
    $test2 = 'test2 string';
    $test3 = 'test3 string';
    $test4 = 'test4 string';
}
?>

test.php

<?php 
require_once("conf.php");

test();
echo $test1;
echo $test2;
echo $test3;
echo $test4;
?>

Why code not worked?

Why weren’t $test1, $test2, $test3, and $test4 printed.

P.S.: preferably without globals parameters.

Answer 1

for the multiple entities you have to use arrays.
So, here is a general purpose solution.
For the certain answer we need a certain question though

function test() {
    $test[] = 'test1 string';
    $test[] = 'test2 string';
    $test[] = 'test3 string';
    $test[] = 'test4 string';
    return $test;
}


require_once "conf.php";

$test = test();
echo $test[0];
echo $test[1];
echo $test[2];
echo $test[3];
