yes,i agree with you,Richard L. Buskirk. process by client-side
script,such as javascript is the best and convenient way.

I see no problem using in_array() for situations like this, and they can
be used in conjunction with a switch if you want as well:
switch(true)
{
case in_array($needle, array('foo','bar','wtf')):
{
// do something
break;
}
case ($needle == 88):
{
// something else
break;
}
}
And it's still quite readable as long as you get your indentation right.

[PHP] gd Graphics Library Question (EXIF)
I have written a lightweight, easy to use photo album "system" in HTML/PHP/MySQL.In addition to the Photo Album side I have written a series of Admin Utilities to manage it with. One of the administrative utilities uploads photos from my local drive, resizes them to be more efficient on disk space, creates thumbnails and populates the database with as much "default" data as can be deduced. After all of this was written, I decided to see if I could pull EXIF data to supply some of the technical data for the DB. To my surprise, the only EXIF data in the JPEG files was data in the File, Computed and Comments sections. Why don't the gd utilities retain the original EXIF data? Is there any way to do so? I use the following gd utilities to resize and create the new JPEG image files: imagecreatefromjpeg imagesx imagesy imagercreatetruecolor imagecopyresized imagejpeg Thanks in advance, Mitch -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I don't know so much about that ...
I'll use a global array to define an application-wide set and then use
in_array to branch dependent on whether some variable has a value that
is or is not a member of that set. Using a series of predicates in a
multiple OR, or using switch is a non-started for me for maintenance
reasons, and the alternative of storing the set of values in a
database is a lot slower. Here's an example:
FWIW, I've got a mapping application. Users can click on a map tile to
indicate a point of interest. However, they can also click on zoom
buttons, or pan buttons. These buttons are named 'plus', 'minus',
'left', 'right', 'up', and 'down' and I have these names in an
application-wide array:
$controls = array ('plus', 'minus', 'left', 'right', 'up', 'down');
The way that these map view controls are handled is very different to
the way a click on a map tile is handled. Somehow, the code is more
readable with:
if (in_array($clicked, $controls)){
// ...
}
than with:
if ($clicked == 'plus' || $clicked == 'minus' || $clicked == 'left' || $clicked
== 'right' || $clicked == 'up' || $clicked == 'down'){
// ...
}
Even using switch isn't as clear IMO as that can intersperse the
options with several lines of code, which can make the logic harder to
spot.
However, the real benefit of using an array comes in making the code
easier to maintain. Drawing my map is a library routine, as is the
handler for the controls. However, the handling of clicks on map tiles
is different for each of the eight or nine contexts in which the
mapping is used. So the best way IMO of coding this is to test in each
page which element has been clicked and to either call a library
routine or a context-specific handler from there.
Now say, for example, that I want to augment the zoom functionality by
having a 'slider' that permits the user to go directly to a desired
zoom level. I can redefine the set of controls by simply changing the
global array. However, using the long if construct mandates that I
must amend the code of every page that uses the mapping, which makes
for a lot of extra work and is just plain silly IMO. IOW, using an
array can help avoid coding inconsistencies.

Re: [PHP] Re: What's faster using if else or arrays?
Hello Jim,
I heard of arrays in the following context:
if (($foo==5) || ($foo=="orange") || ($foo==88) ..
So *that* would be done much better and cleaner with arrays.
$FoosArray=array(5, "orange", 88);
if (in_array($foo, $FoosArray)) { ... }

how many entries are you talking about, ie., how many conditions?
Obviously
if you have more than 4-5 it's going to be easier to code up as a case

Never in all my days have I ever heard of using an array for such a

In my case, one of the controls I'm considering is a tiled map with up to 16 tiles. This is on a page with four tabbed sections that takes several seconds to load at broadband speeds. Also, the nature of the site means that people may need to access it and use this form while connected via mobile broadband or even GSM; connection media that are usually both slow and paid for per unit of data transfer. I need to record in hidden input fields the location of where a user clicks on the map and also echo that click back in the form of a marker overlaid on the clicked tile. Using AJAX, I can update just the two fields plus one image. Without Javascript, the extra bandwidth needed to unnecessarily download the entire page multiple times will cost my users both time and money. So while I must ensure the site works without Javascript, I really need the optimisation that JS brings. > Lastly, if you're creating the website for a government or business, you > really need to make it work without Javascript, as a lot of countries > make it illegal to discriminate against a disability, which you would be > doing if you made a site that was unusable without Javascript.

However, The Disability Discrimination Act requires only that reasonable steps be taken to avoid discrimination ... and making stuff accessible to the disabled at considerable inconvenience and/or expense to everyone else is not considered reasonable. Now where I can, I'll produce stuff that is enhanced by images, colour, JS etc. but will still be usable in Lynx. However, some stuff (e.g. mapping) won't work without graphics and so is inherently unavailable to the visually impaired. It makes no sense whatever to try to make such content work in speech and Braille browsers. Thus making a site that's unusable without Javascript doesn't necessarily constitute unlawful discrimination! -- Geoff -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

This will allow you to check if the browser indicated by the user agent. However, there are caveats to this approach: * A browser might be sending the wrong user agent string, there are plenty of plugins which do this * A browser might be capable of running Javascript but might have it turned off or otherwise blocked * Filtering may be going on by a proxy server or firewall that strips out Javascript (sounds stupid but happens in paranoid businesses) Like everyone has mentioned thus far, it's better to use progressive enhancement or try to avoid relying on Javascript at all. Even a website as complex as Facebook allows users to go on it without needing a browser that runs Javascript. Something as complex as Google Docs has a very clear need for Javascript though, so you wouldn't expect that to work without it. Lastly, if you're creating the website for a government or business, you really need to make it work without Javascript, as a lot of countries make it illegal to discriminate against a disability, which you would be doing if you made a site that was unusable without Javascript. After all, there are many speech and Braille browsers out there that can't take advantage of Javascript, and a lot of Javascript apps which require mouse interaction to run (mouseover/hover events, etc) -- Thanks, Ash http://www.ashleysheridan.co.uk

This is somewhat similar to some index pages. When new file or folder is
added to the directory, HTML page should display the newly created

in alphabatical order)
How to achieve this sort of functionality in PHP? Please provide sample

OK, maybe not the most elegant ... but it works for my purposes ... and
it was my first attempt at these directory functions. You can navigate

Thanks again, -- Geoff Geoff: You are correct about "first contact" -- you need to launch the browser to check to see if the browser has javascript enabled. There's currently no way for the server to see what the user has selected for their browser before the browser launches. It is true that the $_SERVER global provides all sorts of information about the requester and I suppose it could also contain the browser's javascript configuration, but it doesn't. However, JavaScript detection doesn't require a user's response, as you have proposed via a form. Instead, you can simply add an "onload()" operation to the page and detect javascript, such as: http://www.webbytedd.com/b1/ajax-js-dection/ Or do it unobtrusively as I have shown before.

[PHP] Nested XInclude in XML
I need to insert a content of an XML node into text of another XML element in the same document. I use XInclude for this purpose. For example: http://www.w3.org/2001/XInclude";> Lorem ipsum sed do eiusmod tempor dolor sit amet, consectetur adipisicing elit It works well when a node what content is inserted from contains only text (e.g., first sql node in the "foo" query in example above). So I have "Lorem ipsum dolor sit amet," in the first sql node in the "bar" query after parsing. That's what I want. But I have a problem when I try to insert a content of a node containing xi:include. For example I have " dolor sit amet, consectetur adipisicing elit" instead of "Lorem ipsum dolor sit amet, consectetur adipisicing elit" in the second sql node within the "bar" query. When I use xpointer without text( ) at end I have the following as content of the second sql node within the "bar" query: http://www.w3.org/2001/XInclude"; db="oracle">Lorem ipsum dolor sit amet, consectetur adipisicing elit It's almost correct, but here are undesirable sql tags. I've tried to use range-inside() function of xpointer in this way: .. consectetur adipisicing elit .. Content of the second sql node in the "bar" query has been changed to this: consectetur adipisicing elit As you can see content of included sql node entirely gone. What's wrong? Am I using XInclude or XPointer in the wrong way? Or may be PHP XML parser (I use DOMDocument for working with this XML document) isn't entirely conformed with XInclude or XPointer standard? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

What happens if you then use isset($_COOKIE['mysession'])? TBH, I don't know and don't have the time to experiment just now. However, this should return false if the cookie has been destroyed but if just set to null or an empty string via Rick's code I suspect it'd return true. -- Geoff -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Thanks, Tedd. That's how I suspected things to be. However, the list was very quiet, I might have missed something, and so I felt it couldn't hurt to ask. TBH I'd already done: echo ""; print_r ($_SERVER); echo ""; and didn't spot anything there that I thought would give me the info I sought - but then I don't know the purpose of every element of that array and $_SERVER is not the only superglobal! > As Yogi Berra once said; "It's always hard to predict things > especially when it deals with the future." However, once the browser has requested a transfer via HTTP that request is in the past and that request is where stuff that lets you know some of the browser's capabilities (e.g. HTTP_ACCEPT) comes from. So it would be possible by a similar mechanism for a browser to tell your script whether or not Javascript (or any other language for that) is available. > However, there are two ways to "kind-of" doing it: > Way 1 -- I place an element in html that is hidden from the user's > view via css (display:none) and if Javascript is ON then Javascript > changes the css so that the element is shown to the user > (display:block). Here's an example: This is the reverse of part of what I've done for the page in question. I had a tabbed interface similar to: [stuff] [stuff] ... However, the second div must be visible if JS isn't available otherwise the user can't access that section. So I've changed the style of the second and subsequent divs to display:block and then used an onLoad routine to change the .style.display and .style.visibility attributes of the second and subsequent divs to none and hidden respectively so that those who have JS get the full DHTML. Now I also using AJAX on that page. However, I can use the fact that the trigger events aren't handled if JS isn't available to just retrieve what's actually needed at the time via AJAX if JS is available or submit the full form if it's not. Of course, that complicates things in the PHP on the server as the script then has to handle both interim and final form submission. FWIW, it's possible to detect whether or not Javascript is available, but not AFAICT at 'first contact' because you need the 'first contact' page to do something to prove that JS is available, from which you can assume that JS is not should that something not be done. For example, you can make the link to a page into a form submission - e.g: Click Here The form is submitted if the browser has JS and so the hidden input field is posted.
