Question

Is it possible to include a file that contains a string value (in this case a comma delimited list of values) as an argument to a function?

For example:

include.php

<?php
'value1,value2,value3'
?>

function.php

<?php
function test($string)
{
    echo $string;
}

test(include 'include.php');
?>

I’ve tried this and it doesn’t work, but is there a way to do what I am trying?

Answer 1

Does include.php have to be a PHP file?

If not, make it an ordinary text file (eliminating the <?php and ?> tags), and use:

test(file_get_contents('include.txt'));

That will just read the contents of include.txt as a string, and of course you can then do whatever you’d like.

Otherwise, using include actually executes the PHP in the file, so you could make include.php contain:

$variable = 'value1,value2,value3';

And then use:

include('include.php');
test($variable);
