On top of being (what I think would be) incredibly slow, it just doesn't sound right. This works fine for me on one site I maintain, though not with readfile(). When testing readfile() always crapped out at around 2Mb, whereas fopen() and a while loop with fread() working perfectly, even for larger files (up to 200Mb). Not tested this on high traffic, though it all depends on how large you files are. -- Richard Heyes -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I've got a few ideas on how to solve this but I want to find one that requires as little administrative overhead as possible. 1. I could add a field to the db for each product that would be used for associated words for a product as well as misspellings. PROS: Very customizable on an individual product level. CONS: Would need to be updated for each and every product individually. 2. Make a field for each manufacturer's record for alternate spellings/keywords. PROS: Little administrative overhead. CONS: Is only manufacturer name based and could not account for specific products. 3. Both #1 and #2. PROS: Flexible. CONS: Lots of administrative overhead. 4. A one-to-many table that associates individual words with product skus. This one is pretty much the opposite of #1 with one key difference: the interface. It would be probably be easier to enter a desired word and then choose each sku from a multi-select dropdown than it would be to go from product to product entering one word at a time. 5. I'm not sure how this would be accomplished from a technical standpoint but it would be nice to have the program know that when someone types in 511 they really meant 5.11. Or (hopefully this isn't a bad example) if they type in dessert (as in cake and icecream) they really meant desert (as in snakes and sand). In my case that wouldn't be a bad assumption since our site will never contain the word desert unless it's a misspelling. What does everyone think? What other options are out there?

Re: [PHP] foreach / unset
The foreach statement works because you are getting the array index
($k) to unset the array item. I think somewhere in the manual it says
it's unsafe because some people might think you could just use unset
($v) to unset the array item. Which wouldn't work because $v is more
of a temporary variable and not a reference to the array item.

this function might change your mind (I take it you have had your Dew by now
:-):
function resolveArgs($args)
{
$args = array_values($args);
for ($i = 0; $i count($args); ++$i) {
while (isset($args[$i]) is_array($args[$i])) {
array_splice($args,$i,1,array_values($args[$i]));
}
}
return $args;
}
basically it flattens a multidimensional array - i use it for handling DB query
arguments (makes it easier to pass around args whilst build highly dynamic
queries)
so intrinsically its not unsafe to manipulate the array - only you have the
potential
to shoot yourserlf in the foot :-) then again both Richard and John have more
than enough
skills to do that anyway ;-)

Re: [PHP] Type of form element
Hello Shaun, Friday, October 28, 2005, 9:00:05 AM, you wrote: Is it possible to loop through all $_POST values to see if it is a checkbox? If so then for that element if it is equal to 'on' then change it to 1 otherwise change it to 0? Yes and no. 1. You can't determine by the POST variable whether it was a checkbox or a text field unless you test for 1/0 or a string, but even then, what if someone types a 0 into a textbox that was supposed to be an address (input validation). The other option is to name the checkbox something like question1_chkbox and do a strstr() to see if the POST variable name contains _chkbox. But you should know what the variable names of your checkboxes are anyways, so I don't know why you'd test to see if it was a checkbox. 2. Only set checkboxes (checked) are passed through POST and GET. This is fine if it's a one time form and you just need to know if they said yes to subscribing to your newsletter, but if it's a form they can go back into to modify settings (i.e. their account) then you need to test to see if they unchecked a box which will not be passed back to you via POST. Basically you'd set all the fields to 1 if the checkbox variable appeared in the POST, and set all the rest of the fields to zero (because if it wasn't in the POST variables, it was unchecked). -- TBUDL/BETA/DEV/TECH Lists Moderator / PGP 0x6C0AB16B __ Geocaching:http://gps.PCWize.com ( ) ( ___)(_ _)( ___) TBUDP Wiki Site: http://www.PCWize.com/thebat/tbudp )(__ )__) _)(_ )__) Roguemoticons Smileys:http://PCWize.com/thebat ()()()(__)PHP Tutorials and snippets:http://www.DevTek.org Some days I feel like I'm just rearranging deck chairs on the Titanic. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I usually place a hidden field with the same name as the checkbox
field before the actual checkbox field. I store my 'false' value in
there. If the checkbox is checked the hidden field is overridden.

error_reporting( E_ALL );
if( isset( $_POST[ 'submit' ] ) )

time).
I also just don't care for the clever crammed syntax and the as

Ok, here we go :)
Isn't looking through reams of hex data a blast ?
Kind of like a hot poker in the eye ;)
curl -l -i http://www.siren.cc/siren/reel/Library/php/zlib.php;
Here are two versions of the SAME test movie exported from Livestage:
One version has compressed movie headers
The other version has uncompressed movie headers
With zLib, I am using gzcompress at compression level 6, and
gzuncompress.
All the string data below was converted from hex with the pack()
function.
The actual php script I wrote for this test is way way below.
The upshot:
1)Using zlib to compress and decompress a movie header seems to work
fine :)
2)Attempting to 'gzuncompress' a movie header that was compressed in
Livestage gives an error.
I doubt this is fault of Livestage which I assume is simply calling
DataCodecCompress or an equivalent function, no ?
3) The Livestage'd compressed movie header output IS NOT THE SAME as
a the zLib'd compressed movie header output
Maybe I am not starting at the correct point in the compressed movie
header string?
hopefully, this is enough to start a dialog.
here is the output:

OK, I was starting at the wrong place in the hex
I misread the QTFF docs which include two more atoms on the next page:
Four-character code Atom type
'cmvd'Compressed movie data
Uncompressed size32-bit integer
The correct output is now:

Isn't looking through reams of hex data a blast ?
Kind of like a hot poker in the eye ;)
curl -l -i http://www.siren.cc/siren/reel/Library/php/zlib.php;
Here are two versions of the SAME test movie exported from Livestage:
One version has compressed movie headers
The other version has uncompressed movie headers
With zLib, I am using gzcompress at compression level 6, and
gzuncompress.
All the string data below was converted from hex with the pack()
function.
The actual php script I wrote for this test is way way below.
The upshot:
1)Using zlib to compress and decompress a movie header seems to
work fine :)
2)Attempting to 'gzuncompress' a movie header that was compressed
in Livestage gives an error.
I doubt this is fault of Livestage which I assume is simply
calling DataCodecCompress or an equivalent function, no ?
3) The Livestage'd compressed movie header output IS NOT THE SAME
as a the zLib'd compressed movie header output
Maybe I am not starting at the correct point in the compressed
movie header string?
hopefully, this is enough to start a dialog.

CR I have a class that won't be instantiated...so basically just a bunch
CR of static methods.
CR How do I call one of the class' static methods from within another
CR method? Can't use this, and self doesn't work...this is php4.
CR Thanks.
CR Class Foo{
CRfunction getMe(){
CR return me;
CR }
CR function getUs(){
CR$us=xxx::getMe();
CR$us.= me;
CR }
CR }
CR echo Foo::getUs();
Just use the class name Foo::getMe()
Class Foo{
function getMe(){
return me;
}
function getUs(){
$us=Foo::getMe();
$us.= me;
}
}
