Right.

Excellent example! I think you've answered my question: I'll have to keep
using both NAME and ID.
Thanks a lot!

Thanks for the help everyone. I have decided to use javascript to
deal with my second problem. I understand that this is not a
JavaScript fourm but I am having some trouble getting my JS function
to work correctly.
Here is my JS code.
function getEquipment ()
{
var mylist = document.getElementById("equip");
if (mylist.options[mylist.selectedIndex].value=="other")
{
document.writeln("<tr>");
document.writeln(" <td align="left">Other</td>");
document.writeln(" <td><input type="text" name="other"
size="20"></td>");
document.writeln("</tr>");
}
}
This is my code for where the function is called
<select name="equipment" size="1" id="equip" onChange="getEquipment()">
<option value="treadmill">Treadmil</option>
<option value="exercise bike">Exercise Bike</option>
<option value="other">Other</option>
<option value="rowing machine"
selected>Rowing Machine</option>
</select>
My problem is when the page loads in a web browser the Option "Other"
is selected every time. From what you can see from my code "Rowing
machine is the one that I want to be shown when the page loads.
Anyway can anyonne tell me why my code is not executing correctly. I
am not too familiar with java script. What I am trying to accomplish
is if Other is selected then add a new table row below the drop down
menu with the content that I have in the function.
If no one can help with this would someone please direct me to a Java
Script Forum.
Thanks

Hi,
I missed the start of the thread but it may be because you have a space in
"rowing machine" for the option.
Try "rowing_machine" or "rowingmachine" and see what happens.
(check your javascript console - in firefox type 'javascript:' in the
address bar without the quotes).

Hi all,
I'm trying to work out threaded apps and I'm trying to use the pcntl
functions.
I can get it working ok without using a database but when I plug the
database in I get 'lost connection during query' errors.
Does anyone have any suggestions or a working example ?
Thanks!
My code:
<?php
declare(ticks=1);
$time = time();
if (!$connection_result = mysql_connect('localhost', 'root')) {
echo 'Unable to connect: ' . mysql_error() . "\n";
exit();
}
echo "Connected ok\n";
$childcount = 0;
$childrencount = 2;
while($childcount < $childrencount) {
$pid = pcntl_fork();
if ( $pid == -1 ) {
die("error\n");
}
if ($pid == 0) {
$childcount++;
pcntl_wait($status);
continue;
}
$qry = "select version() AS version";
$result = mysql_query($qry);
if (!$result) {
echo "error: " . mysql_error() . "\n";
} else {
$row = mysql_fetch_assoc($result);
echo $row['version'] . "\n";
}
exit();
}
echo 'took ' . (time() - $time) . ' seconds' . "\n";
?>

My code:
Your code works for me, *most* of the time - say, 96%++. I tested
with small values for $childrencount (2 up to 200). I'd hesitate to
speculate, but it smells like an SQL server performance issue to
my weak nose...(IANAE).

Hi Kevin,
Thanks for testing it. I got the same when I was using postgresql for the
database so I thought I was doing something wrong.

Hello List
I would like some advice from PHP users regarding PHP and the command line. I
have a PHP script that does a whole bunch of stuff to a file on my intranet.
./edit.php filename var1 var2
Everything works fine but I need to run it on a list of files -
./edit.php invoice00212.txt var1 var2
./edit.php invoice00213.txt var1 var2
./edit.php invoice00214.txt var1 var2
I have a list of several thousand files that will change every month. The list
has the filenames and variables, like this so I am half way there I think -
invoice00212.txt var1 var2
invoice00213.txt var1 var2
invoice00214.txt var1 var2
My question is how should I incorporate this with my PHP script?
I read that it's better to split scripts up into small reusable parts so my
plan is to keep the logic out of the edit.php script and simply pass the
variables to it using another script. Am I on the right path doing this?
I am only a beginner with PHP so I admit I dont really know what Im doing,
that is why I am asking for pointers from the PHP Mail List :)
Below is my model, however I am unsure how to achieve this or even if it's the
best way to do it?
open filelist.txt
for each line create $filename $var1 $var2
then run
./edit.php $filename $var1 $var2
loop back to the next line
end
Many thanks in advance,
Ang.

That is a good ideology, but whether it's best for your script depends
on the data. I, personally, would probably split it up, just to keep
things clear and separated so when I go back to it later, I can more
easily modify it..

end
That looks good to me. It's not too difficult to jsut throw something
together with the file() function. If your file gets really big you may
want to look into reading the file line by line with fopen() / fgets().
But if you're going to be running it once a month only, file() should
work fine.
Many thanks in advance,
Ang.

I realized my problem and fixed it.
For the future, a doctype is required no matter what ;)

I have a block of XML that looks as follows:
<name><*_~_*> Røyken VGS <*_~_*></name>
Now, if I run that block of XML through htmlentities, I will get the
following:
<name><*_!_*> Røyken VGS <*_~_*></name>
XML parsers will return a problem, as there is both an unclosed tag and
an invalid tag, in two places no less (however the error will occur on
the first "tag".
In order for this particular XML file to parse properly, I -must- run
html_entity_decode. This causes quite the predicament as if I were to
then run htmlentities() on this portion of the file, it would produce
quite a bit of chaos.
My question is, can I in any way efficiently (i -stress- efficiently, if
anyone read my previous XML and special characters post its a rather
large XMl file (breaking 18mb now) and speed is of the essence) cause
html_entity_decode to not decode those tags?
Or any other way would be nice too, I'm pretty much open to anything...
as long as it doesnt severely hurt the efficiency of the script.
(I discovered the error of my ways in the previous problem btw, having a
doctype helps... me == brainded in that :s)
