javascript:document.write('!DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.0
Strict//EN http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd;' +
document.getElementsByTagName('html')[0].innerHTML);

technically the page has already been loaded (Javascript is just adding
more text). I fear the case will be the same if the current page's
source is sent to a new browser window.
I'm not asking for any coding suggestions, necessarily--just curious as
to whether or not anyone knew if this will invoke browser validation
events or not. Comments and questions are more than welcome, though. :)
Can't you do it via PHP using a GET parameter? Seems more likely to work
properly since it requires the page be reloaded on a fresh slate. While
at the same time, it will easily jump through the doctypes that the
server deems suitable given the parameter

Rob,
Absolutely. However, requiring a server-side script was something I was
hoping to avoid. It may be useful as an intranet utility somewhere down
the road, but a bookmarklet was what I was shooting for for this first
test.
Great minds think alike, eh? :)

Why don't you show us some of the attempts that you have tried that didn't work. When you say that you need to match on some of the text, give us an example of the text that you are trying to match.

Re: [PHP] function_exists question
Is there a way to check not only if a function exists, but also to check that the number and types of parameters desired match a function definition? The reason being that additional options have been added in php 4 and 5 to various standard function calls, but I'm still running a php3 and php4 server in addition to a php5 server. I would like to make sure that certain extended function calls still work in all versions (or I'll perform the tasks manually, albeit less efficiently). One example I can think of is the round() function. The $precision parameter was added in php4, so will not work in php3. However, function_exists would return TRUE for both 3 and 4, but round itself would fail if I tried to send a precision level to the php3 server. Thanks much, Matt P.S. Of course the modified function_exists would unfortunately have to be a recognized function/method in php3 in order for me to call it to check parameter counts on a php3 server :( I am sure you have some good reasons for keeping php3 right? Why don't you consider updating to at least php4 ?? PHPv3 is not even maintained and PHPv4 is not being developed any more. So by the end of this year (I hope) we will start using a stable PHPv6.

Re: [PHP] function_exists question
Why can't you update to Version 5? I might be a bit anal about trying to
always get the newest version of everything, but seriously version 3 has
surely more known security issues as well as performance costs.
What's the cost of upgrading compared to the cost of writing code that works
in every version? I think upgrading the system to PHP 5 will take you maybe
half an hour, while you can spend a lot more hours on writing backward
compatible code. PHP is not very good with compatibility across versions
anyway. Hopefully all PHP 5 code will work in PHP 6.
How about this PHP developers: You could make a global variable (or
constant) the user can set like
define('PHP_COMPATIBLE_VERSION', '5.0.1');
or something to tell PHP 6 to interpret it like PHP 5.x . That way, at least
you are guaranteed that the code will work like on that version. It might
make PHP 6 (a lot?) bigger but it might be worth the cost, since all Sites
written in PHP will still work. The functions could still have a performance
boost that way if there are better algorithms.

php5 introduced this:

to make sure php5 interpreted php4 code in a b/c way, they may do
something similar for php6 - php5.

one instance exists all text from first {{ to last }} is included,
can
anyone point out where I am going wrong?
preg_match_all(/\{\{lang:(.*)\}\}/, $str, $tags);
You need the ungreedy modifier:
preg_match_all(/\{\{lang:(.*)\}\}/U, $str, $tags);
FWIW, you can tell just the .* to be un-greedy using a ? like so:
preg_match_all('/\{\{lang:(.*?)\|\|/', $str, $tags);
Correction:
preg_match_all('/\{\{lang:(.*?)\}\}/', $str, $tags);

You overlooked the ampersand in front of $retval. The syntax for
'system' is:
string system ( string $command [, int $return_var ] )
You have to pass a pointer to the variable, not the variable itself.

Actually, that's not entirely correct while the documentation
shows it as a reference variable, it's not actually required to be a
pointer. And in either case, the OP had the error code returned
(127), and $retval would have nothing to do with causing the error.
What I would recommend trying is:
?php
exec('./gpsbabel -p -r -t -i gpx -f test.gpx -o kml -F
test2.kml 21',$ret);
print_r($ret);
?
On a side note, I'm curious as to what 'gpsbabel' does. I've
worked a bit with Keyhole markups and GIS overlays, etc. Neat stuff.

The while would work if you removed elements of $my_array inside the
loop, but you would still need to be sure that it would eventually be
empty.
I would guess that your lecturers point is that you shouldn't call
count on every iteration as it's a waste of time. He may also be
confusing while for foreach in which case I'd leave because you're

thx.
Probably the easiest way for doing this is using foreach:
$a = array(1,2,3,4,5);
foreach ($a as $i) {
print $i.br;
}
This outputs:
1
2
3
4
5
This for e.g. gives an infinite loop:
$a = array(1,2,3,4,5);
while ($a) {
print $i.br;
$i++;
}
So you are right because $a will always evaluate as true since it not
empty. For these kinds of questions you should read the manual first and
then ask here.

Maybe someone here might have an idea. Here's the url: http://masoncollision.com/contact.php In both Safari and FireFox for the Mac (I have not tested it with other browsers) as the page loads the map border is momentary drawn twice. The map border is shown stacked one above the other making the page much longer than it actually is. But immediately thereafter, the map is drawn correctly and the page returns to the size it's supposed to be. I just want to get rid of the momentary flash. Anyone have any ideas? tedd, I think it might be displaying your extra divs (if there are any.. just skimmed the source momentarily) for a split second before they are hidden with Javascript. Maybe try setting the CSS for your 3 map divs (mapsearch, idlediv, searchdiv or whatever) to display:none and show them when the page is loaded? Or give all 3 the same top/left coordinates, etc... Just a shot in the dark. I may read over the code a bit more if I get some time later today.

think the point of this is to count the items in an array without count
mate :p no point in the above you could just:
$c = count($a);
I thought the point was to avoid count() on every iteration.
not using count() but instead looping the complete array is stupid,
if the OP's teacher thinks count() is bad then that teacher suck's,
count() is efficient as it can be ... it does'nt actually do a
count when it's called merely looks up the length property of the
array (unless I'm grossly mistaken)
foreach!
$a = range(1,10);
$c = 0;
foreach($a as $b) {
$c++;
}
echo $c. PHP_EOL;

task: add the numbers 5 and 17 together, using php, without using the +

I'll assume no post/pre-increment operators either.

function add($a, $b) {
$a = array_merge(array_fill(0, $a, 1), array_fill(0, $b, 1));

not very efficient :-) .. probably one of a 1000 ways to fudge it :-)
And another... :)

Maybe try setting the CSS for your 3 map divs (mapsearch, idlediv, searchdiv or whatever) to display:none and show them when the page is loaded? Or give all 3 the same top/left coordinates, etc... Just a shot in the dark. I may read over the code a bit more if I get some time later today. I'm no expert, but I've been working with the Google Maps API rather extensively lately, and maybe I can offer a fresh set of eyes. HTH, Todd Boyd Web Programmer Todd: That would be great. Also, if you see anything there you like, of course you may use it. I think the div's are Okay -- I always check my code through the W3C validator and that does a good job of checking that. I wish that Google and W3C would decide on what's acceptable. I also tried display: none via css, but could not get the right combination of hide/display to make it work right. However, I'll look into your suggestion. If you can find anything to correct, that would be good. But it's just a minor annoyance and I thought someone might readily know what the problem was.

While you teacher technically is wrong, you probably could implement
something using the next() and current() array functions, though you're
best to just use a foreach loop. foreach was designed specifically as an
array looping construct, so it's optimized pretty well.
Only thing to note with the foreach is that you are actually working on
a copy of the array, so if you intend to modify it, pass it by reference.

Close. It actually looks like this:

This makes sense because for each iteration of the loop, PHP places a
copy of the key in $key, and a copy of the value in $value. Therefor,
you are specifying with this code that you want it to place a reference
of the value into $value.

This is not good because you are calling count every loop iteration.
