Or use stat() to get the page's mtime, something like
<?
$stat = stat($HTTP_SERVER_VARS['SCRIPT_FILENAME']);
$date = strftime("%c", $stat[9]);
print "Last update: $date";
?>
Which will be automatically updated...

It'd be easier to sort if you changed your date format a bit ... what you have is rather difficult to work with, unless you take the string apart. (i.e. - How is '7102002' not greater than '6122002'?) For simplicity & ease, I work with date strings formatted as "YYYYMMDD". If your files were named "something-full-YYYYMMDD", you could get a sorted array of your files easily.
$interestingFiles = array(); $dir = opendir( "/path/to/directory" ) or die( "Could not open dir" ); while( $dirEntry = readdir( $dir ) ){ if( ereg( "full-([0-9]{8})", $dirEntry, $MATCH ) ){ $interestingFiles[$MATCH[1]] = $dirEntry; } } ksort( $interestingFiles );

Well quickly looking at the code I can't see what line is causing the Warning: Cannot add header information but there have been many discussion explaining why this happens... as for your Unknown MySQL Server Host '$198.63.221.3' the error for that is on the line: if(!($link_id = mysql_connect($198.63.221.3, $Ultimatefootball, $kjames1973))) die(mysql_erorr()); I think the line would look better like: $link_id = mysql_connect('198.63.221.3', 'Ultimatefootball', 'kjames1973') or die(mysql_erorr());
(might be a good idea to change your password now btw (since you have shown everyone))
Hope that gets you started

This is totally not PHP related. There is a page-break: before; (or similar) in CSS, so I suggest you go look around some CSS sites... like the W3.org.

Hello all,
I am trying to import a 400 meg pipe delimited text file, but I am having problems. For some reason, it will only read in 320 lines and then it will cause a core dump. I have used this same script to import a 350 meg file with no problems. I have talked with my support and they believe it could be some type of problem or limitation with php.
Can anyone offer any advice on how to track this down? When I look at the core file, this is what it says..."core: ELF 32-bit LSB core file of 'php' (signal 11), Intel 80386, version 1"

Not sure how to supress the warning message that PHP automatically does when you haven't got a valid URL though.
should be able to surpress errors by adding an * before the result variable

Hope this helps--or even works for this particular problem. Hugh

Error reporting options can be set in php.ini or by using ini_set().

I think you mean '':
$fp = fopen($linkdata['linkurl'],"r");

The code that I have is as such:
//header.php if(isset($_POST['login'])){ $checkuser = mysql_query("SELECT * FROM mainacct WHERE username = '{$_POST['username']}' AND password = '{$_POST['password']}' ", $connection) or die ("Couldn't find user."); if (mysql_num_rows($checkuser) > 0){ while ($row = mysql_fetch_array($checkuser)){ $_SESSION['UN'] = $row['username']; $_SESSION['UserLoggedIn'] = True; } } else { header("Location:login.php"); exit; } }
This file is then used as an include in main.php. As long as the variables are used ONLY in the header.php file, it works. But when I try to call the session variables in main.php, it doesn't show the values of UN or UserLoggedIn. session_start() is called in main.php. Is this a quirk with sessions, or is there something more I am supposed to be doing? Running Apache 2 w/PHP 4.2.3 on WindowsXP.

Hiya ^_^
I have a guestbook I coded myself using PHP. In the corner it keeps record of the entry number, but when I delete and entry the entries posted after it don't go back to catch up. So the entry numbers skip from 22 to 24, for example.
Is there anyway to stop this happening, so if i delete an entry the next one will follow on instead of being the number it would have been if i hadn't deleted the entry?
Thanks ^_^

Hi,
you give less information. How do you compute the entry number and how do you save the entries and so on. Normally you will have to live with the gaps but sure, you can touch every entry and change its number ;-).

You're probably using some kind of 'autoincrement' field for your entry number.

The short answer is if you want that kind of behaviour then you shouldn't be using an autoincrement field.
The quick solution, if you intend to continue the autoincrement field, is to number the entries manually when you're displaying them: Something along the lines of:
$count = 0; while ($row(mysql_fetch_array($result_id))) { $count++; echo "Entry $count"; ... ... }

attached mail follows:
in mysql the autoincrement field will not go back to fill gaps...
and this is for a good reason ...
suppose you had an entry (bogus1) in your guest book with entry number 23 and you deleted it...
now a new entry comes and it is given the entry number 23 ... well this ambigus : did u delete the original one or modified it ? also people pointing to that particular entry in their sites will be confused by the change... where as in the real life we usuallay offer a "record does not exist" type of message ...
got it ?!

Hi,
I would like to post the following question related to an inheritance problem with PHP OO programming :
With an object of a subclass, I call a method of the parentclass in order to modify an attribute of the parentclass. It does work correctly but later when I call the display method of the parentclass, I receive the previous value of the attribute !!!
The code below shows the problem : The parentclass is "Ressource" The subclass is "Water" The attribute of the parentclass is "$volume" The method to update $volume is "increase" The method to display the parentclass is "display"
An explanation and a trick to fix the problem would be greatly appreciated.
Thanks !
Bernard
