I tried the following code, but it is not working. Please help!

<?php
for ($i=1; $i<=10; $i++)
{
$x=file_get_contents('core/$i');
echo $x . '<br>';
}
?>

Answer 1

You are setting $i as type text by mentioning it in ''

Change your code to

<?php
for ($i=1; $i<=10; $i++)
{
$x=file_get_contents('core/'.$i);
echo $x . '<br>';
}
?>
