RE: [PHP] Searching for text in a file
Hi Richard,
First, I think it should be:
$variable = "[EMAIL PROTECTED]";
instead of:
> $line_text= "[EMAIL PROTECTED]";
as you overwrite $line_text with your fgets.
Also:
> if ($variable = trim($line_text)) {
Should be:
if ($variable == trim($line_text)) {
Otherwise you are doing an assignment, which will always be true.
Finally, your while loop should probably be:
while(feof($fd) == false) {
$line_text = fgets($fd, 2048);
Because fgets returns EOF at the end of a file, not necessarily false (I
THINK EOF currently is false, though theoretically EOF could change to any
value).
Cheers,
Kelly.

RE: Re[2]: [PHP] Searching for text in a file
Richard,
I just put together a script using that code exactly, and it worked.
All I can say is make sure that what you are searching for is actually in
the file you are searching.
Remember that the string you are searching for needs to match the entire
contents of the line, not just a substring of the line.
Try some simple tests that you know are sure to work. i.e. Make a
virtusertable file that is just a couple of lines.

Re: Re[4]: [PHP] Searching for text in a file
Richard,
Then you need to use something like "explode()" to get only the part you
want.
e.g. If the file is delimited by spaces, then have something like this:
$fd = fopen ("virtusertable", "r");
$variable= "[EMAIL PROTECTED]";
$count = 1;
while(feof($fd) == false) {
$line_text = fgets($fd, 2048);
$strings = explode(" ", $line_text);<--- Splits the line at
every space into an array of string
if ($variable == trim($strings[0])) {
echo "Match at line number $count";
break;
}
++$count;
}
If the file is tab delimited, you will need:
$strings = explode("\t", $line_text);

Re: [PHP] php4 and apache on SuSE Linux
Hi Sean,
What webserver are you using? Is it using the Apache module of PHP or the
CGI version?
Perhaps the extension of your file doesn't have the PHP processor associated
with it (if it is installed as an Apache process)?
Maybe you are using the CGI version incorrectly?
With the command line version, you still need the tags before it
will process the PHP code.
e.g.
#!/usr/bin/php
That should work as you expect.
Cheers,
Kelly.

Re: [PHP] php4 and apache on SuSE Linux
It sounds like the PHP isn't getting parsed. Check the webserver is
configured correctly for the extension of your file, or that your system
requires you to use the CGI version of the PHP interpreter.

Re: [PHP] PHP Security
Hi Allen, What you should do is check the session variable from within PHP. If it doesn't exist, you redirect to a PHP authentication form. So at the head of each page you need something like: And in your PHP authentication form, you register the logged_in variable after the user details have been authenticated: Cheers, Kelly. > I have been using the .htpasswd/.htaccess convention to authenticate our > 3000 employees. > I want to move away from the .htpasswd/.htaccess convention and use a PHP > form to authenticate against the database. > > I can create the PHP authentication page, no problem, but how do I check > authentication on the thousands of HTML pages I already have on the site? > For several reasons I don't want to do cookies.

RE: [PHP] Getting ip address of client and displaying a number in decimal format.
Troy,
$REMOTE_ADDR gives you the client IP.
To convert a number to show 2 decimals use "sprintf":
$money = 5;
$money_string = sprintf("%.2f", $money); // $money_string will be 5.00
Cheers,

You need to set the expire time. Set it to 10 years in the future or

$expire_time = time() + (86400 * 365 * 10);
setcookie("cookie", "value", $expire_time);

Re: [PHP] another easy cookie question
Hi George,
You must output all headers (including cookies) before you output any
content.
So, you just need to move your header and setcookie calls so they are above
the and tags.
