all you need is
if( false !== strpos($SSL_PROTOCOL,"SSL")) || false !==
(strpos($SSL_PROTOCOL,"TLS")) )

Sample script:
(Note, this will never report SSL even when $SSL_PROTOCOL=SSLv3 or TLSv1)
<?php
echo $SSL_PROTOCOL;
echo "<BR>Your connection method is: ";
if ( (strpos($SSL_PROTOCOL,"SSL")) || (strpos($SSL_PROTOCOL,"TLS")) )
{
echo "SSL!";
}
else
{
echo "non-SSL!";
}
?>
The documentation says strpos() returns FALSE if no match. But what about a match on the first
character (index 0)? Seems like the index returned should have been 1-based instead.
The routine is flawless when the code is rewritten thusly:
<?php
echo $SSL_PROTOCOL;
echo "<BR>Your connection method is: ";
if ( (strpos($SSL_PROTOCOL,"SL")) || (strpos($SSL_PROTOCOL,"LS")) )
{
echo "SSL!";
}
else
{
echo "non-SSL!";
}
?>
