Can someone recommend me some really fast template engine? I am making
my own template class and I would like to test it's speed against some
best template engines out there. So far mine is way faster than Yapter
(about 8 times) and just a little bit faster than Smarty (about 1.2 times).
Donny
PS. tests were made by doing some big loops to make a table so it
doesn't cover all aspects, only the main one.

Hi all, am a newbie to PHP so please spell your answers to my questions out
in words of one syllable or less...
I recently had PHP 4.2.1 installed on Windows 98 SE, then it suddenly
stopped working for some reason - I don't know why or how, but I kept
getting SErver 500 errors. Having tried to remove all traces of PHP from the
Windows OS and tried to install the latest version (4.3.3), both with the
ZIP manual installation and the EXE self-install program, I still get
problems. Can anyone please please help, cause I really need PHP on my PC to
finish development of my local dramatics society's website and the
intermediary between me and the Society will puncture my jugular if I can't
get it working within the next week.

P.S. Am running PWS/IIS 3

Why are you trying to do the job of the DBMS in script ? Try instead :
$query="SELECT nrviews FROM url WHERE url=".$url;
$result=mysql_query($query);
if (mysql_num_rows($result)==0) {
$query="UPDATE url SET nrviews=nrviews+1 WHERE url='$url'";
} else {
$query="INSERT INTO url (url,nrviews) VALUES ('$url',1);
}
mysql_query($query);
This gets the one or zero rows which conatin the unique URL, and does a
second query which either updates the existing row by one hit, or inserts a
new row with a value of 1 hit.

Subject: selecting and updating fields
Hi !
I've got a form that passes a variable to a script.
The script connects to a database and I need to check if a field
containing that variable already exists in the table, and if it does, to
select the "nr_of_views" field, increment it, and update the table and if
it doesn't, to create a new field with that variable and set nr_of_views to 1
the table in my database that looks like this :
url nrviews
www.google.com 1
www.yahoo.com 3
And I've tried something like this:
$query = mysql_query("select * from url") or die (mysql_error());
while ($row = mysql_fetch_row($query))
{
if ($url === $row["url"])
{
$nrviews = $row["nrviews"];
$nrviews++
mysql_query("update url set nrviews='$nrviews' where
url='$url'") or
die (mysql_error());
}
else
{
$nrviews=1;
mysql_query("insert into url (url,
nrviews) values ('$url','$nrviews')") or
die (mysql_error());
}
}
AND STILL DOESN'T WORK !!!
When I get a variable that is not in the database, the whole thing goes
crazy ! (it inserts lots of fields with that variable and nrviews=1
Please HELP !
Thank You !
