<0> TML: i'll have to look into this, you've peaked my interest in this now
<1> TML: I've noticed minor variations though when using em... but *shrug* I'm no expert :)
<2> zircu: :)
<3> i've read that some font experts says that it should be "ex" as the standard, except that we can't use it now because of browser inconsistencies
<2> I've never used em in place of pt because its meaning is confusing in the font-size context.
<2> I mean, it means one thing everywhere *EXCEPT* in font-size, where it means something completely different.
<3> TML: em is much easier to use in standards mode. quirks mode adds in some headache
<2> deadroot: I always write in standards mode.
<2> " The 'em' unit is equal to the computed value of the 'font-size' property of the element on which it is used. The exception is when 'em' occurs in the value of the 'font-size' property itself, in which case it refers to the font size of the parent element."
<2> (quoth the specs)
<2> I read that paragraph as basically saying "Don't use em" :)
<2> Thus, I always use pt size for fonts, and percentages for everything else.
<4> woot
<0> "pt: Differs greatly between resolutions"
<3> after parsing that language, it was "1em is always equal to the computed font-size, unless the font-size is specified with em. in which case, it will be relative to the parent element."
<2> zircu: That's right. Point sizes scale at precisely the same rate as resolutions do.
<0> TML: so basically your saying that pt gives a more reliable scaled font
<2> zircu: "more reliable"? Hmmm...
<2> zircu: em is reliable, if in a confusing (to me) manner.
<2> It's easier for me to conceptualize a point size's scaling method.
<3> couldn't 1pt = 72px and 1pt = 720px on different monitors?
<0> well, there are some gotchas as you quoted above with em's
<5> 1 point = 1/72 of an inch
<3> zircu: the quoted text basically says em is like percentages
<4> what's the point of me putting public $var; at the beginning, php don't need it to initiate right?
<4> beginning of cl*** i mean
<6> Froshs: it's good practice
<3> Froshs: for clarity
<0> Froshs: it self documents as well as initialized the object with the default value (if specified)
<2> Froshs: If the value doesn't change, it's static. Therefore, it should be declared statically, so that everyone who reads the cl*** understands that the cl*** expects this value to be consistent.
<0> TML: http://www.w3.org/QA/Tips/font-size
<0> ^ that strayed me from pt
<4> so I should define every variable i plan to use just for good practice, clarity?
<4> constructor sometimes seem unneccessary
<7> if i want to print a line of code repeatedly in a loop structure, is there a way to do it without using echo or print , but instead with an alternative control struture?
<3> "Avoid sizes in em smaller than 1em for text body, except maybe for copyright statements or other kinds of "fine print."" < is not a completely good idea. i would initialise the body to 0.7 or 0.8 em first, at least for IE and Fx
<0> yeah, i would only define a constructor if it is needed
<0> Geren: an alternative control structure?
<2> Geren: You can't print using a control structure
<7> huh?
<7> i mean instead of doing while { echo" " }
<7> is there a way to do it wthout using echo in each iteration
<2> You said "without using echo or print, but instead using an alternative control struture". control strutures cannot replace echo or print, because control strutures cannot generate output
<8> Geren: No, and what difference does it make?
<7> i mean
<7> like shortened form
<8> echo is only 4 characters
<8> you could do a function and have it a([TEXT HERE]) and that save a single character
<2> Geren: You can store a value until you've done whatever it is you're wanting to do, and then only call echo at the end.
<0> $. = 'printf'; while(1) $.('hello');
<0> hmm.. . isn't valid var ***ignment :)
<2> zircu: WHAT IN THE NAME OF...?!?!
<2> Why would you even *TRY* such a thing, you monster?
<6> zircu: come on, you can do better than that
<0> TML: i was trying to make it as short as possible
<7> i heard you can do it without using :"echo"
<2> zircu: is "." shorter than, say, "p"?
<4> I know this wouldn't be recommended, but is it possible, does it even work, if I copy a working script into a cl*** method? and just call it out?
<0> TML: depeneds on the font :)
<2> heh
<2> zircu: I suppose. I always use monospaced fonts.
<0> same here, it just percieved as shorter for me
<2> Froshs: It depends on what the "working script" does.
<4> because I want to make it into OO
<6> Geren: why would you want to do it without echo? it's 4 letters
<4> as a learning experience and hope it works :D
<6> $a = '', $$a = 'printf'; while(a) $('hello');
<6> now _that_ is obscure
<2> aidan: If I *EVER* end up cleaning that up somewhere, I'm holding you personally responsible.
<6> * while(1)
<6> haha TML
<9> lol
<2> Although it is rather wickedly delicious
<2> ah...doesn't work, unfortunately
<6> oh?
<6> is there an error?
<2> parse error at $()
<6> dammit :(
<0> yeah something is odd with that
<6> eval!
<2> heh
<0> aidan: now you are getting desperate like i was
<6> $a = '', $$a = 'test'; echo $; does that work?
<2> Can you imagine, looking at someone's code, 15 includes down from $a=''; $$a='really_hairy_function_with_lots_of_side_effects';, and trying to figure out what the hell $(); does, and why it breaks EVERYTHING?
<2> aidan: Nope. Again, breaks at the lack of an identifier after $
<0> yeah parser doesn't like $;
<2> heh
<2> aidan: Here you are
<2> $a = ''; $$a = 'test'; echo ${NULL};
<6> ah, that is ***y
<4> just wondering for fun would this work, a different portion of a script, can break it into methods, and then call each methods after another?
<6> ${} work?
<2> $a = ''; $$a = 'printf'; ${NULL}("T");
<7> no actually i meant like <?="adsfasdf"?>
<7> the short form of echo
<2> No, {} breaks at }
<4> would it read like a whole script as without cl***?
<2> Geren: That's deprecated. Don't use it.
<2> Froshs: The question doesn't make sense.
<7> well what else could it mean by alternative loop structure then!?
<2> Geren: That's not a loop structure
<4> say you have a whole script
<6> Geren: that's not the short form of echo ... You can't use that in a block of PHP code. If you're not in a PHP block, then yes, that would work (until the next version of PHP)
<4> break it at random lines
<2> A loop structure is while, do/while, or for.
<4> put each in a method
<6> Froshs: ... one line per thought please
<4> then just call them out
<2> Geren: "Alternative loop structure" refers to the use of: while(test): code; more code; endwhile;
<4> would that work?
<2> Geren: And such constructs.
<6> Froshs: and yes ... if you do it properly, it will work fine ... and that's the beginning of writing OOP code
<7> TML, yes that's part of it, but that does not eliminate the echo statement
<4> good to know
<7> i want an alterntive structure wthout echo
<7> yet still have those lines printed
<3> "$a = ''; $$a = 'test'; echo ${NULL};" :O
<10> I reinstalled PHP4 and it's working with PHPBB, but now it's telling me it cant read or write files
<6> Geren: .. could you get over the not wanting to use 'echo' please?
<10> What do i need to change to fix that?
<6> Jaywalker: #phpbb :)
<2> Geren: Then call print, printf, var_dump, printr, or some other output generating function or statement.
<10> aidan: not a problem there
<10> refering to earlier
<10> it's a PHP problem
<7> i think it meant using that short tag thing
<10> it won't let me read or write anything to a file
<2> Geren: "that short tag thing" is deprecated, and you shouldn't use it, because it's going away.
<6> Jaywalker: If your PHPBB install is not working, it is a #phpbb problem
<2> (Just in case you don't understand what I meant by "deprecated")
<10> aidan: you didn't read what i said
<7> ok , oh well
<7> alright i'll work on it
<0> if you dont want much typing use something like BF
<10> the problem has no relation to PHPBB
<10> the problem is with my own codes that worked before
<6> Jaywalker: ... Then why did you mention PHPBB?
<4> wow, OO really needs planning
<4> unlike other stuff
<10> aidan: i was talking about it earlier
<2> Froshs: yes, that's the general idea behind OO
<2> Froshs: Spend more time in planning and less in debugging.
<10> The issue i'm having is PHP can't read or write to any file with fopen
<4> but once its done, it's suppose to make everything easier right?? combine this with that?
<6> Jaywalker: what's the error given?
<2> Jaywalker: permissions on files is the most likely problems.
<4> like phpbb, they do that in cl***?
