I want ppi! I've no doubt that this is another case where the answer is painfully obvious and my mind to dull, but I've spent the better part of the day searching usenet groups and the PHP docs and come up with naught. I'm running the current Cent OS distribution of EL, PHP Version 4.3.9 with, of course, GD support. Any suggestions would be most appreciated. Thank you. Simon [EMAIL PROTECTED] There is no way you can do it. To have on screen e.g. 40 ppi or 80 ppi when the image has a size of 400x400 pixel you would have to read out the image how big a pixel in it is. at 80 ppi you would have your normal image and on 40 ppi the pixels used per dot would be duplicated. you still have 400 pixel in width and you would not be able to count the pixels who got duplicated. If you are lucky it's written in the file. Otherwise no chance. The normal screen resolution is: with an average of 0.26 mm ~ 3.8 pixel/mm ~ 97 pixel per inch. No matter what kind of resolution you would choose (800x600,1024x768 etc.) an image having for example 48ppi would have pixels that use 2x2 pixels (4 pixels) as one colored pixel and so on. Now guess what you see when you have 194 ppi. Nothing, it's still 97 ppi because it's not possible for the screen to view anything else. Normally the screen would just duplicate the imagesize from 400x400 to 800x800.

RE: [PHP] making php code from db work
The only two ways I can think this could work is you must either write the output to a file with a php extension and then include that file, or you must set up the apache server to parse html files in the same way as it does php files. Just doing a normal output on a standard server won't recognise any server-side script in that output (which is what you've already experienced).

Can't you name it as just favourite (without brackets) You need [] for it to be an array in PHP -- otherwise you only get one value no matter how many are checked. If you name it as just favourite, at least in Javascript you could loop through favourite as an array. I don't know if this works in PHP as well. It's easy enough to treat it as an array in Javascript with the brackets -- you just have to understand the equivalence between objects and arrays. Cheers!

$_COOKIE, $_SERVER, and $_ENV.
When PHP creates $_REQUEST, it does so by adding the global arrays
together in a certain order, namely EGPCS. Normally, this would be
OK, but if two (or more) of those arrays have a key with the same
name, then that key value will be replaced with the last value read.
For example, the value provided by $_GET('mykey') will be replaced by
the value found in $_COOKIE ('mykey') in generating the value for
$_REQUEST('mykey').
So, if you use $_REQUEST, then you can't reply upon where its values
are derived.

[PHP] PHP files in the SRC attribute of an SCRIPT element
Hi everybody, Does anybody know if it's possible to specify a php file as the src attribute of an script element in a html page. For example: script language=JavaScript type=text/javascript src=d:/projects/horde/dimp/js/DimpCore.js.php?Horde=b9d9e640abf31e49eab7fad91a543bb5/script I've installed the HORDE framework (www.horde.org) and I'm trying to make their AJAX web client work. It seems that this line of code causes problems. The DimpCore.js.php file is a file that has ?php ? tags between javascript lines. Are you allowed to do this? I mean, is the php file parsed by the PHP engine first and a js code is generated that will be used by the script element? I know this list is only for PHP issues, but I thougt maybe someone had the sameproblem and knows a workaround for this. Any ideas would be appreciated. Thank you! Christi Zeck

I wonder how Paint Shop Pro comes up with PPI (Image - Image information). I have several thousand scanned images with resolution ranging from 72 PPI up to 1200 PPI (As reported by Paint Shop Pro) and want to discard, or more likely tag as rejected, any that suffer a resolution of less than 150 PPI. As you might imagine, I find the thought of doing it manually with Paint Shop Pro repugnant. Okay, if it was scanned at 72ppi then you can't really print it out again even with a near-similar quality. However, having an image with a 72ppi does NOT necessarily mean that you have an image unsuitable for printing. PPI or pixels per inch is a printing term. Last time I checked, dpi is the printing term. (^_^) dpi (dots per inch) - printer ppi (pixels per inch) - monitor/screen Still missing it.. Yes, dpi is a printing term.. but has absolutely nothing to with with images. dpi or Dots per Inch is purely a term that describes the limits of your printer. If for instance, we are talking about an ink jet printer with a 600 x 600 dpi capability, with black and three colors, that printer can print any of the four color or not print in a space 1/600th of an inch as it moves along. And there is no blending within that one dot... it's simply one of the colors or left the white or the paper color. One might think that an image should be scanned at 600 dpi to provide and equal quality, but really you can scan at a much reduced resolution and get the same results with a basic inkjet color printer, because the scan will most often be done at 16.7 million colors.. the printer only has 4(+paper color) so it really takes a 4x4 dot area or so to start to get close to matching a single pixel. Now, lets don't even go there on printers. The above is greatly understated and was how old inkjets worked.. much has changed and I really haven't followed exactly what they are doing now, but obviously it seems that there is a blending over top of other colors in today's printers. Just trying to provide simple theory, quick to type, easy to grasp. So, yet still ppi is being misrepresented.. Please stop doing this. If you don't believe me try this. Open a quality paint program. In fact, Macromedia's Fireworks in the image sizing dialog box separates pixel dimensions from ppi putting ALL ppi function under the heading of Print Size. The example. Open or create an image 600 pixels x 300 pixels. Make sure you stay at 100% zoom factor. Set the printing Pixels/Inch to 150, but don't let the program change the Pixel dimensions. You will be given a print size of 4 x 2. The image will take up 600 x 300 pixels of your monitor screen space. Now with that same image, change only the resolution to 300. Leave the pixel dimensions the same (one has to be careful with the locking of proportions and samplings to be sure the program doesn't change the pixel dimensions when changing the Pixel/Inch). You will now see that the print size is 2 x 1, but yet the image size on the screen has not changed sizes. A pixel is a pixel to a monitor. A pixel is sent thru an algorithm on the way to a printer and by and large, print quality has to be much greater than monitor quality to 'look' as good. Basically, you can't get a 4 wide image on the screen to look as good when printed at 4 wide. A general guideline is images for print should be no less than 150 ppi, newspaper quality, and 300 to 600 is recommended for color brochures and near photo quality. So, using our example above and assuming the printing company has requested 300 ppi images, that image at 600 x 300 which fills a major portion of one's monitor screen, can only be printed under this constraint at a maximum of 2 inches x 1 inch. If you're going to print, check with the printer before beginning as print quality is generally rising at all levels. The question of throwing away all images with 72dpi is irrelevant. The questions are: What resolution, pixels per inch, do you want to print at? Lets assume 300. What size are the images in pixels? Lets assume 1200 x 900. (I know, odd size but easy math to follow) Are you happy with printing these images at 4 inches x 3 inches? ((1200 pixels / 300 pixels per inch = 4 inches) x (900 pixels / 300 pixels per inch = 3 inches)) If yes, keep the image. If you started with an 8 x 10, scanning at 72dpi and are happy with 150ppi, you can get a good print out at 4 x 5. If you want 300ppi, then 2 x 2.5 inches.. and so on. Also, if working in .jpg filetypes, there is normally a quality setting in the paint program. If you're going to print, set it to the highest. If to the web, medium to medium high is generally not a noticeable difference. My testing showed that these settings affect the number

[PHP] print page from php
All, I have a web page with the results from several database queries. Now this page has an undefined horizontal and vertical size. Does anyone know if there is a php script available that will automatically split the webpage into parts that can fit on an A4 page? Or do I have to set boundaries on the size of the tables the queried data will be shown in.

I have several thousand scanned images with resolution ranging from 72 PPI up to 1200 PPI (As reported by Paint Shop Pro) and want to discard, or more likely tag as rejected, any that suffer a resolution of less than 150 PPI. As you might imagine, I find the thought of doing it manually with Paint Shop Pro repugnant. Okay, if it was scanned at 72ppi then you can't really print it out again even with a near-similar quality. However, having an image with a 72ppi does NOT necessarily mean that you have an image unsuitable for printing. PPI or pixels per inch is a printing term. Last time I checked, dpi is the printing term. (^_^) dpi (dots per inch) - printer ppi (pixels per inch) - monitor/screen Still missing it.. Yes, dpi is a printing term.. but has absolutely nothing to with with images. dpi or Dots per Inch is purely a I beg to differ... (see next) term that describes the limits of your printer. If for instance, we are talking about an ink jet printer with a 600 x 600 dpi capability, with black and three colors, that printer can print any of the four color or not print in a space 1/600th of an inch as it moves along. And there is no blending within that one dot... it's simply one of the colors or left the white or the paper color. One might think that an image should be scanned at 600 dpi to provide and equal quality, but really you can scan at a much reduced resolution and get the same results with a basic inkjet At a much reduced resolution? Try scanning some photo, say an A3 size photo, at 72ppi. Then, try printing that at 600dpi on the same A3 size paper and see what you get. color printer, because the scan will most often be done at 16.7 million colors.. the printer only has 4(+paper color) so it really takes a 4x4 dot area or so to start to get close to matching a single pixel. Now, lets don't even go there on printers. The above is greatly understated and was how old inkjets worked.. much has changed and I really haven't followed exactly what they are doing now, but obviously it seems that there is a blending over top of other colors in today's printers. Just trying to provide simple theory, quick to type, easy to grasp. Add to that that some have 8(+paper color). And that not all people are using inkjets. So, yet still ppi is being misrepresented.. Please stop doing this. Who is misrepresenting what? ;-) If you don't believe me try this. Open a quality paint program. In fact, Macromedia's Fireworks in the image sizing dialog box separates pixel dimensions from ppi putting ALL ppi function under the heading of Print Size. The example. Open or create an image 600 pixels x 300 pixels. Make sure you stay at 100% zoom factor. Set the printing Pixels/Inch to 150, but don't let the program change the Pixel dimensions. You will be given a print size of 4 x 2. The image will take up 600 x 300 pixels of your monitor screen space. Now with that same image, change only the resolution to 300. Leave the pixel dimensions the same (one has to be careful with the locking of proportions and samplings to be sure the program doesn't change the pixel dimensions when changing the Pixel/Inch). You will now see that the print size is 2 x 1, but yet the image size on the screen has not changed sizes. Of course! A pixel is a pixel to a monitor. A pixel is sent thru an algorithm on the way to a printer and by and large, print quality has to be much greater than monitor quality to 'look' as good. Basically, you can't get a 4 wide image on the screen to look as good when printed at 4 wide. That's correct. And nobody said otherwise. A general guideline is images for print should be no less than 150 ppi, newspaper quality, and 300 to 600 is recommended for color brochures and near photo quality. So, using our example above and assuming the printing company has requested 300 ppi images, that image at 600 x 300 which fills a major portion of one's monitor screen, can only be printed under this constraint at a maximum of 2 inches x 1 inch. If you're going to print, check with the printer before beginning as print quality is generally rising at all levels. The question of throwing away all images with 72dpi is irrelevant. 72dpi !== 72ppi Just to make it consistent, an image on the screen cannot have a dpi whereas a *printed* image can. The questions are: What resolution, pixels per inch, do you want to print at? Lets assume 300. What size are the images in pixels? Lets assume 1200 x 900. (I know, odd size but easy math to follow) Are you happy
Re: [PHP] Session from php in ASP
PHP and ASP both have built in session handling. The only problem is, they instantiate the sessions themselves. Therefore, whenever you hit a page in ASP you'll start one session, but if you immediately hit a PHP page on the same server in the same browser from the same machine, you start a brand spanking new PHP session. It'd be possible to write a handler that wrote information in and out of cookies and a DB and effectively merge the two systems into using the same handler. Alternatively, you could use (un)serialize(); in PHP (along with the ASP equivalent) to store data in files, but I don't see that as being as efficient for this scenario. -Myk OLeary [EMAIL PROTECTED] BLOG: http://www.blueneedle.com/wordpress/?bnphplists On Mar 17, 2006, at 4:22 AM, Stefan wrote: Hi NG is it possible to get a Sessionvariable set in php read in an asp- file with the tag %= Session(php) %?

Re: [PHP] Converting a string
You're best off using an array that matches human readable form to field name as someone else suggested earlier. Form names for basic fields like this should be standardized such that auto form fillers (aka Google toolbar) are able to work. They won't know that your field named hmnrdble_F-irst_N-ame equates to a first name field. Skip the dastardly regexp and keep it simple. On the posted to page populate the array with boolean values as you do you boundary checking. If you fail, then save it to session, redirect back to the form, read the array from session, and you have access to ALL fields that failed, so you can not only have a message at top, but the ability to mark each field with a style or some such to visually draw the user to what they need to fix. -Myk OLeary [EMAIL PROTECTED] BLOG: http://www.blueneedle.com/wordpress/?bnphplists On Mar 17, 2006, at 11:21 AM, Jay Blanchard wrote: [snip] Then you should change the name of the field.

Well, you didn't answer the second question, how would you do it? So
far I see a pattern: ignore the lowercase letters at the beginnig and
add a space before an uppercase (this won't apply to all field names,
and I hope you're aware of that), so try something like
$text = preg_replace('/^[a-z]+\s*/X', '',
preg_replace('/(?=[A-Z])/X', ' ', $name) );
Now, a better way, IMHO, would be to use _ as spaces and write the
name of the field as you want it to appear (e.g. First_Name), so you
just need to
$text = str_replace('_', ' ', $name);
--pretty much simplier, isn't?
And... if you want to add a prefix (such as ps) then make it
configurable, so it can be changed anytime without effort.
Last comment: you should think about the question you didn't answer, and
that might give you the solution to your problem.

I expect that I can take a string, like 'psFirstName' and change it to
'First Name'. that way I don't have to worry about what some web
designer named his fields, I can turn them into human readable strings
without having to manually create a new array.
So far I have this
$newKey = preg_split(/([A-Z])/, substr($key, 2), -1,
PREG_SPLIT_DELIM_CAPTURE | PREG_SPLIT_NO_EMPTY);
Which returns;
Array
(
[0] = F
[1] = irst
[2] = N
[3] = ame
)

I was just headed in the wrong direction with preg_split(), and I had it
stuck in my head.
If I had delimiters, such as underscores, this question would have never
come up. I am not in a position to tell the designers that we need them
to change their naming conventions in forms at this unfortunately, so I
need to work with what we have as efficiently as possible.
Thank you for an elegant solution, but I am curiouswhy would it not
work with all field names if they were named using the conventions
(studly caps)? I can see a problem perhaps with a field named fooMyURL,
it would come out as My U R L. Do you feel as if there are any other
gotcha's?

Re: [PHP] Converting a string
IMHO, you do are in position to tell the designers how the fields should be named, after all they won't give any use to them, it's you (or the developer in turn) who will deal with them. Besides, using underscores (or any other space-replacement) anyone knows beforehand what the text displayed will be, and any special combination of lower/upper-case letters it's preserved. Anyway, right now it seems this is something we can't depend on, so let's refine the expression a little. Oh, and I was refering to the same problem with fields such as MyURL. I've changed a little the pattern, now it would say ignore the initial lower-case letters and spaces (if any of those) and add a space before any upper-case wich is not preceeded by an upper-case, and also those upper-case followed by a lower-case, so it now would look like $rex_initial = '/^[a-z]*\s*/X'; $rex_upper = '/(?![A-Z])(?=[A-Z])|(?=[A-Z][^A-Z])/X'; $text= preg_replace($rex_initial, '', preg_replace($rex_upper, ' ', $name) ); I think that solves the problem with the previous one. But I'd also like to point out that most of us (you included, if I understood right) seem to agree that this shouldn't be the first option, but something simplier --this is more like a patch than a feature ;) Good luck with the designers :) Jay Blanchard wrote: [···] I was just headed in the wrong direction with preg_split(), and I had it stuck in my head.
