Re: [PHP] Pixel Length of text message
Font-size is the height of text, the width is changing w/ every font (e.g. i and m). If you use exactly one font, you may use an array of widths(which you measured before), but that's not really exact. Perhaps, a way would be to use temporarly gd (ttfbox and/or imagefontwidth), but I don't know how exactly, it's just an idea, regards, jan - Original Message - From: District Webmaster [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Monday, April 29, 2002 6:17 PM Subject: [PHP] Pixel Length of text message In html/css you can set a font size in pixels -- in my experience this means a letter takes the same number of pixels, regardless of resolution. With php, can I use string length and font pixel size to determine the length of a given string on a screen? Does anyone know an algorithm for this that works for any/every font? -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] In Addition to [PHP] PHP Security
Sorry for answering with a new question. But, what's if, say, the PHP-Parser crashes (or a filename is changed) and Apache returns the source. How is it simply possible to store passwords somewhere a httpd-users won't see it? (e.g. in the includes-Folder, am I right?) And are session-variables send per post or does the next script reads it from the session-file so nobody can't read them?

[PHP] Stop to fast caching/parsing
Hi List, my Problem is, on the second line of my script I validate a session. If it's false, it dies. But in the first line, I require a header(html,body,title etc.). Now, if a session fails, my die-Message ends in a script-Part, so nobody sees it but gets an error by JS. Is there any way to stop parsing PHP before flushing out required headers? Thanks, Jan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Stop to fast caching/parsing
But I WANT to do something else, loading other code! But ok, I will check at first, then include a short header before dying. This runs, but isn't beautiful. Thanks.

If you use files you might get the contens of the folder where sessions stored and just count.

[PHP] Display large text fields in html
Hi List, I want to display large text fields if a user changes wants to, like a dictionary. for example, a php-database generated page hosts a combobox filled with ids, if a user changes it, a text otherwhere changes. Simple Javascript would you say, but what's if this combobox has about 1000 entries(every entry about 10lines of text)? The page loads and runs very slow. But I don't want to reload the page everytime the user changes the field. Do you know any solution? I know a few: a) As is said, a 2nd textbox filled with value coming from array. b) The box is filled by a set of textfiles which are generated before c) above but w/ layer d) no box but an image, b/w-gif generated by php e) inline-frameset which is reloaded f) an applett which get its resource by getURL g) ... As I said, do you know which would be the best? Thanks a lot, Jan PS. Yes, I think this is rather a PHP question. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Re: Display large text fields in html
Ok, but true frames load very slow - not on an intra, but on internet. The select is not the problem, I use cursors to output every line. At first I did an implementation like yours but users said it's to uncomfortable (they like static VB-Tools). Then I asked JS to reload a frameset using a LIMIT-query from 50 +/- of selectedIndex and then just reload if a new index is out of this range, but for me there is no ability to hide/show these fields from JS. So i think i would have to use an Applett?

Not inline-frames, but a true frames. So each change can load the frame and show the information. Also, a select with 1000 entries? Break it apart. For example make one with (imagine this is a select in your browser): /--\ Abba Bee Gees|V| Beethoven Coolio| ManyOptions ZillionOptions | \---/ It's an interval of choices, first the user selects the interval, which loads another select with only these in between entries. -- Julio Nobrega.
