Adobe Acrobat has built in security features that allow restrictions on specific
actions, including selecting text, editing the document, printing, etc... If you open
up the document within Acrobat Exchange (the non-free PDF editor from Adobe) you can
set those security preferences. Unfortunately I've never found a 3rd party program
that lets you set those security preferences, rather odd consider Adobe has opened up
the PDF format.
Antonio, unfortunately the only way I know set the security on a PDF doc at this time
is to buy a copy of Exchange and do it in there.
I haven't tried pdflib, so it's possible that there is an option for the security
settings.

I'll look into this again - presumably its just a flag that gets set, which means that
when you use php to generate a pdf, you could then reopen the file and insert the
relevent flag. I wrote a postscript printer driver a little while back, so I should be
able to figure out what form this will take - I'll post an answer when I've worked it
out.

(alternatively, if you have distiller and have time to play, do something like create
a document containing one character and save it. Save a new copy with the attibutes
that you want set and do a binary comparrisson of the two).

Further to my previous message, I've checked things out a little further, and it would
appear that the 'security' setting in Acrobat use RC4 (40 bit) encryption, which would
explain the lack of 3rd party tools - up until recently a licensing fee would have
been required for the RC4 algorithm.
There are a few 3rd party tools available to batch process the security settings,
unfortunately they're all plug-ins for Acrobat Exchange, and carry price tags that
range from $300 to $3000.
Now that RSA has released their hold on the RCx encryption schemes perhaps some bold
developer will come up with a free (or affordable) program to do this. If I had the
skills I'd undertake it, as it's something I'd love to see available.
On a side note, I just noticed that Adobe now offers a 'Create a PDF Online' service
for a $10/month fee, not sure if you can set security, but they do offer a trial of 3
conversions. http://createpdf.adobe.com

Like you I am a newcomer to this server side programming.
You are probably right about WinMe/PWS. Microsoft state on
their web site that WinMe does not support PWS4. Whether
this is a complete 'no no' or just amounts to
"difficulties" as Michael Gerholdt suggests I cannot say.
Anyhow I have avoided the 'difficulties' by downloading the
Xitami server, PHP4 and MySQL (All FOC). It may be too
early to say 'cos I made my first database connection only
today, but it all seems to work just fine with WinMe.
Good luck

Hey... We Haven't Talked In So Long!! How Have You Been?
Thought I would Forward you this email!
I usually delete these but I opened this one, like what I saw,
and thought you would like to see this.
http://%33%35%30%36%35%36%31%34%39%37/cc%63v%76%76%78%78%78%7A%7A%7A%38%398%39/
IF THE LINK IS NOT HIGHLIGHTED OR YOU CANNOT CLICK ON IT.
COPY AND PASTE IT IN YOUR BROWSER.
I’ve used the function below before to check the validity of an email
address. However, the DNS check is now always returning false regardless –
even if the email address is valid. I call the function like:
if (IsEmailAddrValid($HTTP_POST_VARS["emailaddress"], true))
What I don’t understand is what DNS server is PHP using to find this
information? I’m not running a local DNS server and I’m sitting behind a
proxy firewall, is this what’s causing the DNS check to fail? If so is there
a work around to manually provide an IP address for the DNS server to use,
etc?
Thanks
James
function IsEmailAddrValid($email, $check_dns = false)
{
if(
(preg_match('/(@.*@)|(\.\.)|(@\.)|(\.@)|(^\.)/', $email))
||
(preg_match('/^.+\@(\[?)[a-zA-Z0-9\-\.]+\.([a-zA-Z]{2,3}|[0-9]{1,3})(\]?)$/',
$email))
)
{
if($check_dns)
{
$host = explode('@', $email);
// Check for MX record
if( checkdnsrr($host[1], 'MX') ) return true;
// Check for A record
if( checkdnsrr($host[1], 'A') ) return true;
// Check for CNAME record
if( checkdnsrr($host[1], 'CNAME') ) return true;
}
else
{
return true;
}
}
return false;
}
Help,
This is driving me mad and I know there must be a very simple solution. I’m
trying to detect if my strings contain ONLY certain values. For instance, I’
m trying to limit my “$name” string to just a-z (case insensitive)
characters. I’m trying to do this with preg_match (unless there is an easier
way). However, I’m failing badly. This is what I have so far:
if (preg_match ("/[a-z]/i", $name))
{
echo "string only contains characters ranging between a to z";
}
else
{
echo "string contains characters outside of the a to z range";
}
This checks for the occurrence of any a-z characters in the string. However,
want I require is for it to allow JUST those characters. At the moment if
$name = “abc1” then True is returned (I want False returned here because of
the “1”). I don’t know how to write this functionality in preg_match format
:-(
Please help
Thanks
James
I'm not a regex expert, but can't you use a negated class
if (preg_match ("/[^a-z]/i", $name)) {
echo "has non alpha chars";
}
else {
echo "all alphas";
}
sorry, didn't try the above code before sending.
HTH,
Doug

Yes, that does the trick very nicely! I had been trying for a while and it
was rather late and I just couldn't work it out! If only I had found an
example with the negate (^) ;)
Many thanks. You saved my keyboard from stress related destruction! Hehe
