Question

I’m currently using the following in my single.php file to list the parent category and child category that my posts belong to:

foreach((get_the_category()) as $category) { 
    echo '<h1>'.$category->cat_name . '</h1>'; 
}

So this results in:
<h1>Events</h1><h1>News</h1>

However, I would like to store each <h1> value in a separate variable.

So my eventual code could be:

$i1 = "<h1>Events</h1>"; 
$i2 = "<h1>News</h1>";

How do I do this?

You want to use a “variable variable”:

$j = 1;
foreach((get_the_category()) as $category) { 
    $i{$j} = '<h1>' . $category->cat_name . '</h1>';
    $j++;
}

However, I would just use an array:

$i = array();
foreach((get_the_category()) as $category) { 
    $i[] = '<h1>' . $category->cat_name . '</h1>'; 
}
