Re: [PHP-DB] [PHP]: session problem

Re: [PHP-DB] [PHP]: session problem
[snip] i do ($_SESSION['sid']), but the variables remain empty... [/snip] If you are using the array forget about session_register. http://www.php.net/session_register Could you post a little code?

Re: [PHP-DB] [PHP]: session problem
do you get any output on the second page if you do this?
?php
session_start();
print 'pre';
print_r($_SESSION);
print '/pre';
if ( isset($_SESSION['logged_in'])){
echo Welcome...;
}else{
header(location: user.php?action=9);
}
?

RE: [PHP-DB] regular expression help
you only want to check to see if there is at least one digit?
If that is true, this should work:
if(preg_match('/\d/',$password)) {
echo 'password ok';

[snip]
That does not work either... I can not make the statement fail!!!
I have tried
$password = 123456;
and
$password = abcdef;
I have change the if statement to what is below and past in all letters
and
it still works?
if (preg_match ('/\d/', $password)) {
die (You must have a number between 2 letters in your password ...
0-9);
// Larry
[/snip]
sorry, this should be:
if (!preg_match ('/\d/', $password)) {
die (You must have a number between 2 letters in your password ...
0-9);

Re: [PHP-DB] help with consecutive numbers in db

Re: [PHP-DB] DB and mssql
[snip] Hi Matt Before sending the result set, the mssql extension stores the entire result set into memory. However, PHP limits the amount of memory that can be allocated by a script to 8MB. So, the query will fail if the result set is larger than 8MB. You can change this value in php.ini with the memory_limit parameter. So, try increasing it and see if it solves the problem. -- bob [/snip] Thanks for the response. If I was hitting the memory limit, wouldn't php throw me some kind of error? Or would it just abort? -- PHP Database Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DB] DB and mssql
I am using PEAR::DB on linux, php 4.3.2, with freetds to access a sql server database. I am trying to get more information on the problem, but everyonece in a while, it seems random, php will stop executing when I use the query method, php stops executing. I dont get an error, php just stops running. I can echo out things before the query call but not after. The query that is running can return large result sets,on the high end it will return 1 - 15000 rows. I am am sql server novice so I am not sure where to start looking to see if the problem is db server side. I am just wondering if anyone has had this kind of problem before. I am not sure if it is something going on with PEAR::DB or if something is happening with the native php calls to sql server. I have not tried to do the query without using pear::db, but I am going to try that to see if I can get the script to error out that way.

Re: [PHP-DB] apache/php/mysql - guarenteed DB transaction

The counter that I use counts everyone every time they look at the site. I want a better counter, can you all suggest one? It's got to work with html and php only. /snip You would have to either set some kind of permanent cookie once the user visites your site, so on every request, check for the existence of that cookie, if it is not there, add 1 to your counter and set the permanent cookie, if the cookie is there, they have viited the site.
