I have a very simple PHP script as follows:
<?php
echo "$$";
?>
On wifi or wired connections, the output is normal, as follows:
$$
But on my cellular connection (which is LTE on AT&T), the output is:
$$0
What's up with the zero in the output?
The issue only seems to happen on AT&T network, I tried on Verizon network and it was working.
Adding this line of code solved the problem:
header('Content-Type: text/plain; charset=utf-8');
