Hi, I'm very new to JavaScript and have found myself needing to select every element by a classname and apply a style to it. Something like: textholder = document.getElementsByClass("redtext"); textholder.style.color = "red"; Obviously the above does not work - my question is, how can I get this to work? I'm also aware that the above can be done easily with CSS, but it's the concept I'm trying to grasp here and not the exact example. Thanks.

Never mind. I just used a conditional CSS statement that makes the margin -13px.

Hi all. I'm working on a website that you can find here: http://gleasonator.com/jolivisage2/ When viewed in FF3, everything looks perfect so far. But for some reason in IE6 my "content-top" has padding on the bottom which separates it from the rest of the page... Here is my CSS so far: #content-top { height:6px; background:#FFFFFF url("images/content_top.gif") repeat-x; padding:0px 0px 0px 0px; margin:0px 0px 0px 0px; } #content-top #corner-left { height:6px; width:6px; background:#FFFFFF url("images/content_corner_tl.gif") no-repeat; float:left; padding:0px 0px 0px 0px; margin:0px 0px 0px 0px; } #content-top #corner-right { height:6px; width:8px; background:#FFFFFF url("images/content_corner_tr.gif") no-repeat; float:right; padding:0px 0px 0px 0px; margin:0px 0px 0px 0px; } #content { background:#FFFFFF url("images/content.gif") repeat-x; font-family:Arial, Helvetica, sans-serif; font-size:12pt; color:#6e6d6d; height:514px; margin:0px 0px 0px 0px; padding:20px 20px 20px 20px; } And the HTML: <div id="content-top"><span id="corner-left"></span><span id="corner-right"></span></div> <div id="content"> stuff goes here </div> Any help would be appreciated. Here is an image:

Thanks a bunch, guys. You rule.

Sorry, but I'm not sure what "encoding" is (I don't have a good understanding, at least). :-\ I did search the symbol, however, and it said that it's a Unicode symbol. It appears on the Windows character map. Thanks for any more help you can give. Please excuse my ignorance of the subject.

Hi, if I want to echo an odd symbol (such as a heart... ♥) is there an easy way to do so? Using echo "♥"; displays this: ♥ Thanks.

Ah, never mind, guys. I got it myself. function get_pattern_name($filename) { $open = fopen($filename, "r"); $read = fread($open, filesize($filename)); $str = substr(bin2hex($read), 1068, 32); $arr = str_split($str, 2); $find = array( "00", "", "", "", "", "", "3a", "3b", "3c", "3d", "3e", "01", "1b", "02", "1c", "03", "1d", "04", "1e", "05", "1f", "06", "20", "07", "21", "08", "22", "09", "23", "0a", "24", "0b", "25", "0c", "26", "0d", "27", "0e", "28", "0f", "29", "10", "2a", "11", "2b", "12", "2c", "13", "2d", "14", "2e", "15", "2f", "16", "", "17", "", "18", "32", "19", "33", "1a", "34", ); $replace = array( "", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "A", "a", "B", "b", "C", "c", "D", "d", "E", "e", "F", "f", "G", "g", "H", "h", "I", "i", "J", "j", "K", "k", "L", "l", "M", "m", "N", "n", "O", "o", "P", "p", "Q", "q", "R", "r", "S", "s", "T", "t", "U", "u", "V", "v", "W", "w", "X", "x", "Y", "y", "Z", "z", ); $output = implode(str_replace($find, $replace, $arr)); return $output; }

Hi guys. I have something a bit weird I'm doing. But here's an example of a hex string that I have. 142c2332231f00000000000000000000 Now, when this is decoded into text, the output is like so: ,#2#���������� The text that I would like to output is: Trixie To clear things up a bit, the hex string is dumped from a portion of a save file of video game. However, in the video game it renders "14" = T, "2c" = r, "23" = i... and so forth. So I would like to convert my "hex" string into a string that can be read. I know what all the values equal, but using a strreplace doesn't work (I have one "find" array, one "replace" array, and a variable containing the string then I use str_replace($find, $replace, $str);) because you get conflicts. When applying a strreplace to: 142c2332231f00000000000000000000 The output is: Tri3h3e Does anyone know of any better way I should approach this? Thanks. EDIT: In case anyone wants to look at it, here's what I have so far. I've actually not gathered all the values yet (as you can see; several chunks in the $find array only have "". But I do have enough that I should be able to convert the hex mentioned above) $find = array( "00", "", "", "", "", "", "3a", "3b", "3c", "3d", "3e", "01", "1b", "02", "1c", "03", "1d", "04", "1e", "05", "1f", "06", "20", "07", "21", "08", "22", "09", "23", "0a", "24", "0b", "25", "0c", "26", "0d", "27", "0e", "28", "0f", "29", "10", "2a", "11", "2b", "12", "2c", "13", "2d", "14", "2e", "15", "2f", "16", "", "17", "", "18", "32", "19", "33", "1a", "34", ); $replace = array( "", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "A", "a", "B", "b", "C", "c", "D", "d", "E", "e", "F", "f", "G", "g", "H", "h", "I", "i", "J", "j", "K", "k", "L", "l", "M", "m", "N", "n", "O", "o", "P", "p", "Q", "q", "R", "r", "S", "s", "T", "t", "U", "u", "V", "v", "W", "w", "X", "x", "Y", "y", "Z", "z", ); $output = str_replace($find, $replace, $str);

This is exactly what I needed. Thanks a ton.

Hi all. Let's say I have a string like so: $string = "Hello world."; And I'd like to have the 6th to 9th characters (for example) split into a different string. Like: $newstring = "worl"; Note that I do not want to "find" characters in the string. When I put this to use, the position of the characters will be what I'll need. As in, characters X to X will always represent the same kind of data, but the characters will be changed. I'm trying to convert something dumped into a text file from an external program into something understandable, and in order to do so I'll need to know if the above is possible. Please let me know if I didn't provide enough information. Thank you, Alex

Thanks for the link. I don't really understand the usage of ZIP, though. You zip_open, then what? How would you extract the files? Thanks again.

Hi, I was hoping someone could point my in the right direction, as Google wasn't sufficient. I have unzipme.zip on my server and I'd like to unzip all the files of the ZIP into a folder called "temp" using PHP. Any easy way to do this? Thanks all.

I would make the headers colorful. Since you're already using red and yellow throughout the page, maybe you should make the headers green or blue?

Thank you, to all three of you. I just got the little light-bulb over my head and went "Ooooohhhh." I have a much better understanding of the logic behind this now, what is exactly what I was hoping to achieve. I love this site. You guys are awesome.

Hi. I'm new to PHP (I'm just learning about functions today), and I have a question regarding "echo" and "return". I do understand that "return" is intended to be used within a function and it seems that it's only intended for use within a function. However, the following is what's puzzling me. This code is from W3C Schools: <?php function add($x,$y) { $total = $x + $y; return $total; } echo "1 + 16 = " . add(1,16); ?> And it outputs as "1 + 16 = 17" as it should, and I understand why it works. But why can't I use "echo $total;" in the function instead of "return $total;"? Like this: <?php function add($x,$y) { $total = $x + $y; echo $total; } echo "1 + 16 = " . add(1,16); ?> I've tried this, but the output from this is "171 + 16 =" Yes, using return does work. I'm not asking for a coding solution, I'm merely asking for the logic behind this that makes it function the way it does. I would appreciate it if anyone could take the time to give me some tips. PHP is something I've always wanted to learn, but I want to LEARN it, not just memorize it... so that's why I'm asking this.
