What the heck is "front end PHP", or am I misinterpreting the bad
punctuation (or lack thereof)?

While that kind of query structure can be a huge issue the biggest
problem, and performance penalty, occurs if the programmer is opening
and closing actual real connections. A good structure would use a
singleton connection that is opened only the first time it is called and
the rest of the time returns the connection object already opened. Or,
use pooling or similar types of things. You will get orders of magnitude
increase in speed by not reopening the database multiple times per page
especially if you are seeing 15,20 or especially hundreds of
connections. Sometimes though you have no real choice but to build a
system that has to generate multiple queries, so don't judge the page
simply on the number of queries but on the completity of the reporting
and the number of database connections opened(you will occasionally need
more than one if you arn't pulling all the results at once, using
cursors or partial retrievals instead and have to have multiple result
sets open at any given time).

Well the system was using one of those not so insightful global database
connections so opening up the connection was not the problem. I'm well
aware of where bottlenecks occur, but I assure you such a system is not
very scalable over a LAN even if you only open one connection. But I
guess it doesn't matter if scalability isn't your concern... until
further down the road anyways... YOUCH. Either way, using a factory to
produce the objects from the row data is much more efficient since you
can use a single query to get all children in one shot. This is still
not perfect due to recursive nature (there are ways to do it without as
some forum discussion have pointed to but I forget the links) but
depending on the branchiness of the tree structure will provide a much
better response time.
As for judging, I guess I was the only one there to see something as
simple as retrieval of product categories and products get really out of
hand. I reduced the queries to under 200... and since we were still only
opening one connection I know the time cost was reduced to about 1/5.
The queries could have been reduced more but it was more work than the
customer felt was worth the additional savings.
Knowing what choices are available is part of competence. If all you see
is one choice, there may in fact only be one choice, or you may be too
inexperienced to see the others that exist.
Cheers,
Rob.

Hey James,
Thanks for replying.
Sorry, I guess i was not clear on that.
Its just one connection, I meant 15-20 queries not
connections.
Thanks!

Dear All,
I'm having a problem replacing these bad characters from a feed.
Example:
<description>The United Kingdom<92>s National Arena Association has elected
Geoff Huckstep, the current CEO of the National Ice Centre and Nottingham
Arena, as chairman.</description>
The <92>is actually a single quote. I have these from some of the data dumps.
I can't figure out what exactly to strip.
When I view the file in vi they appear like <92> <93> <94> (highlighted in
blue like controll characters.
Can someone point me in the right direction to purge this from my feed?
Thank you,

You want str_replace with arrays as parameters.

I understand I need to do a string replace.
Should I do it like so?
$search = array(chr(145),chr(146),chr(147),chr(148),chr(150),chr(151));
$replace = array("'","'",'"','"','-','-');
Is this what you mean?
Thank you,

Anyone have a PHP fragment that just prints a very simple html table
from the contents of a db result set? I don't want phpmyadmin or anything
remotely that complex. I want something that simply extracts the header
info and prints a basic HTML table. It should be about 10 lines of code
I suspect. If so, can you post it?

Writing code in a mail window, so forgive any errors or ugly code. This
will print a table with the first row as headers of the field names, and
each row after that is a database row. I hope.
$firstrow = true;
echo "<table>";
while ( $row = mysql_fetch_assoc($result) ) {
if ( $firstrow ) {
echo "<tr>" . implode("</tr><tr>", array_keys($row)) . "</tr>";
$firstrow = false;
}
echo "<tr>";
foreach ( $row as $value ) {
echo "<td>$value</td>";
}
echo "</tr>";
}
echo "</table>";
Essentially what it does is, loop over each row, and if we're the first
row, write out the headers, and for all rows, write out each field. I
haven't tested this, just typed it up from memory now, so I'm not sure
if it'll compile.

On second thought, I'm not sure why I didn't use implode for the second
one too, it makes things simpler (and possibly faster):
$firstrow = true;
echo "<table>";
while ( $row = mysql_fetch_assoc($result) ) {
if ( $firstrow ) {
echo "<tr>" . implode("</tr><tr>", array_keys($row)) . "</tr>";
$firstrow = false;
}
echo "<tr>" . implode("</tr><tr>", $row) . "</tr>";
}
echo "</table>";
And BTW, this code assumes that you've done your MySQL query and have
$result as the return value of a mysql_query() call or something.

You don't need to pull the headers from the data, actually. You can access
the fields in the result object directly.
$result = mysql_query($sql);
echo "<table>";
echo "<tr>";
$num_fields = mysql_num_fields($result);
for($i=0; $i < $num_fields; $i++) {
echo "<th>", mysql_field_name($result, $i), "</th>";
}
echo "</tr>";
while ( $row = mysql_fetch_row($result) ) {
echo "<tr><td>" . implode("</td><td>", $row) . "</td></tr>";
}
echo "</table>";
The above should work, I think. :-)

Ok, I've been tinkering a little. This isn't "simple" but it's not a
lot of code either.
Basically the user supplies an array of "cell renderers" associated
with column names. Each renderer is a function name that will be called
to modify an array() representing an HTML TD element. The result is
printed to yield an HTML table. I think this is pretty extensible. You
can render columns or individual cells differently depending on the text
or position of the coloumn or cell. You can format numbers and dates,
render buttons, ... whatever you want.
The first column renderer below renders every odd column a light shade
of grey. The second renderer demonstrates formmating a timestamp. The
third renderer colors the background of an individual cell green if the
numeric value is greater than 1000.
I'm a C person myself. Can someone clean this up / improve on it (e.g. how
can I pass parameters to renderers?).

Hi gang:
Why does starting my php script with --
<?xml version="1.0" encoding="utf-8"?>
-- stop it from running?
I would like to use php in a page, but the page has to begin with a
xml declaration to generate a quirksmode for IE6 and under while
permitting IE7 to be left in standards mode.
We've tried it in both Wordpress and Textpattern and both are php and
neither are able to parse a document with an xml declaration above
the header.
Is this problem solvable? I've been told that better minds have
already tried and failed to resolve this issue.
So, what say you group?
Thanks in advance for any replies, comments, explanations, or solutions.

Disable short tags.
If short tags are enabled, the PHP parser sees the <? and switches into PHP
mode. It then starts parsing the "xml" and sees that it's not proper PHP,
and freaks out.
You can:
a) Use PHP to print out the XML declaration as a string:
<?php print '<?xml version="1.0" encoding="utf-8"?>'; ?>
b) Disable short tags so that the PHP parser ignores <? and only recognizes
<?php.
The correct answer is (b). (PHP 6 won't even have short tags, so get used to
not having them.)

Hi Jay ,
I am not in the javascript group.
Btw , i have added document.forms['listfrm'].pageid.value in the
page , but the form is not submitted ?
var pageid = document.forms['listfrm'].pageid.value;
var urlpath = "../listflag.php?start=&pageID="+pageid;
document.forms['listfrm'].method = 'post'; --> did not submit form
at all
document.forms['listfrm'].action = urlpath;
document.forms['listfrm'].submit;
Any ideas why ? How to submit form when user change value in the select
tag ?
Thanks

It will produce the html tag as shown below:
<script language="JavaScript">
function gotoPage(){
var urlpath = "../listflag.php?start=&pageID="+3;
document.forms['listfrm'].method = 'post';
document.forms['listfrm'].action = urlpath;
document.forms['listfrm'].submit;
}
</script>
<form name="listfrm">
Go to Page:<select name="pageid" class="inputfield"
onchange="javascript:gotoPage()">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="4">4</option>
<option value="5">5</option>
</select>
</form>
I tried using onchange in the select tag,but it did not work. It go to
the javascript but the form is not submitted .
Anyideas why?

In gotoPage() you're not referencing the value of pageid
(document.forms['listfrm'].pageid.value). More of a JavaScript question,
are you a member of a JavaScript list?

My guess is that PHP only sees / compares the strings up to a

around this, so that my whole string is seen?
Greetings and thanks in advance,
Nils
Maybe it's interpreting something as a number somewhere. Did you
try using === instead of == for your comparisons?
Ah, thanks, that made it work! :-)
PS: Why is your license key so insanely long, and why doesn't it
use alphanumeric characters to reduce the length?
Very good question, I should probably ask the person that came up
with the way this license key works. Even if it has to be this long
"internally", I've been thinking about using some encoding / hashing
technique to make it smaller at least when it's being passed to the
PHP script. For the sake of testing, however, I didn't really care.
Greetings and thanks again!
Nils
