[PHP] user auth
I will soon be developing a user authentication system with different access levels. I
will need to check the users against a mysql database. How secure is checking for a
session var, and then redirecting with header('Location:...') ? Is there a way to get
around this method of protection?

Re: [PHP] Problem with file()
Zambra - Michael wrote: What kind of line ending does the file() function include in the array elements. I'm having problem with file() combined with implode() when reading in complete HTML files in a Windows environment. After parsing these resulting strings I get tons of white lines (??). I'd appreciate any advice. When it puts each line into the array, the newline is still attached, so if you are adding more newlines when parsing this could be the problem.

Re: [PHP] str_replace question

Is a nicer way to remove any number 1-0 from a string???
Currently:
$metakeywords=str_replace(1,'',strtolower($metakeywords));
$metakeywords=str_replace(2,'',strtolower($metakeywords));
$metakeywords=str_replace(3,'',strtolower($metakeywords));
$metakeywords=str_replace(4,'',strtolower($metakeywords));
$metakeywords=str_replace(5,'',strtolower($metakeywords));
$metakeywords=str_replace(6,'',strtolower($metakeywords));
..
use a regular expression with ereg_replace(), like this:
$metakeywords = ereg_replace('[0-9]', '', $metakeywords);
hope that helps

The code I just wrote will not print out Hello! You can use variable variable names by adding another '$'. so if $i == 1 and $var1 == one, you can do this: $var_name = var.$i; if($$var_name == one) echo Hello!; That should work, Justin -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] smarter way to write config file?
Justin French [EMAIL PROTECTED] has the same first name as me :)
and wrote:
Currently i've got a config file for each website, and I split it into
essentially two config files, based on the server name, so that I can have
1
file for both my local server and the live server.
something like:
?
if($local)
{
$cfgAdminEmail = [EMAIL PROTECTED];
$cfgReportErrors = 1;
$cfgSendMail = 0;
}
else
{
$cfgAdminEmail = [EMAIL PROTECTED];
$cfgReportErrors = 0;
$cfgSendMail = 1;
}
?
But of course, there's more like 20 config elements. The small problem
I'm
having is making sure that I keep both halves (live and local) the same
(but
with different settings).
What i was hoping was that there may be a way of writing the config once,
and having it work in both situations, perhaps with a switch, or with some
other language construct I have no idea about:
I know this isn't the answer, but I was hoping for something like:
?
$cfgAdminEmail = [EMAIL PROTECTED]|[EMAIL PROTECTED];
$cfgReportErrors = 1|0;
$cfgSendMail = 0|1;
?
Where both the options local|live were declared in one hit.
Whatever solution there is (arrays? switches?) it has to be easy to
maintain, otherwise it's a step backwards I guess.
Any suggestions appreciated, or pointers to stuff in the manual i've never
heard of!!!
You could do it by making each variable an array with a key of 'local' and
'live' like this:
?
$cfgAdminEmail = array(local = localaddress, live = liveaddress);
etc.
etc.
?
Then you could set something like $server to local or live
and refer to the var's by $cfgAdminEmail[$server];
