[.class and #class ?]

To go a little further,

Say you had a generic class called red

[code].red{
  background-color:#902100;
}[/code]


[code]
<li class="red"></li> ..
<td class="red"></td> ..
<span class="red"></span> ..
<span class="blue"></span> ..[/code]
[list][*]You code apply that to many types of tags.[/list]

If you wanted to beforehand in the css, you could call them out by tag and id.

[code]span .red{  font-size:1.6em;  }[/code]
[list]
[*]This line only effects spans that are "red"
[/list]

[i]tag & class[/i] are one way to further divide class and id. It all depends on how many children you want your elements to have. Inheritence.

I try to use classes for things that I'll most likely reuse, and ids for the known one-timers.
That said, the more I use javascript, the more that I'm dropping [b]id[/b]s all over the place. I'll try to find a way to style away from the script. The last thing you need is style and javascript breaking together.

[Change CSS???]

This will write the actual new file.
I've done this before, and I've always had to refresh the browser make it kick in.

[code]<?
//include_once(me?)
//******** styleWrite.php [ ?col=336699 ]
// look for this file to be written:
$newFilename='styles.css';

$content='body{background-color:#'.$_GET['col'].';}';

$loc=$_SERVER['DOCUMENT_ROOT'].'/'.$newFilename;

if( ($copy=fopen($loc,'w')) != FALSE)
{
fwrite($copy,$content);
fclose($copy);
$message= "I think i got it" . $loc;
echo $content;
}
else $message= "couldnt open destination file";
echo "<!-- " .$message." -->";


?>[/code]

[Change CSS???]

Aha. That's a job for javascript.
The good news is that you wouldn't need to post.
What css rules are you changing?

[save a webpage]

Here's a script that'll do better.
It'll output all the html as it is, AND hook you up with a local hard copy.

[code]<?

//set these yourself//
$newFilename='copy.html';
$url= 'http://dev.mastercontrolprogram.org';


if($f=file_get_contents($url))
{
$loc=$_SERVER['DOCUMENT_ROOT'].'/'.$newFilename;

if( ($copy=fopen($loc,'w')) != FALSE)
{
fwrite($copy,$f);
echo $f;
fclose($copy);
$message= "I think i got it" . $loc;
}
else $message= "couldnt open file";
}
else
$message= "i dont know about ".$url;

echo "<!-- " .$message." -->";
?>[/code]

[Upper/Lowercase in MySQL/PHP]

[code]
# stuff i just ran on mysql 4.1

SELECT name FROM table WHERE 1 AND name="[b]myname[/b]";
# returns  '[b]MyName[/b]' from table.


[b]select [/b]name from table where name='banner'
# would return [b]Banner[/b]
[/code]

[Getting the _FULL_ URL]

Nope. I guess not.

# is a client side element.

PHP would never be aware of it if the anchor id first appears after the page is loaded.

What are you trying to do?
Javascript might be able to do it.

[Getting the _FULL_ URL]

$_SERVER['REQUEST_URI']  ??

[Is it possible?]

put this in your post handler.

[code]
$body= "Someone posted this \n";

foreach($_POST as $k=>$v)
{
  $body.= "[$k] => $v \r\n";  //<-- for mail, you may want the carriage return \r
}


mail ('you@yours.com',$body,'From: yourfile@yours.com');[/code]

[Best way to edit your PHP code???]

  JEdit !

Got rectangular select ?  ;)

[Apache and IIS]

I'm going with Apache.
Have you counted the IIS related problems in this forum? lol.

The filetypes will be a little foreign, but heh, you learn a little bit about Linux on accident.

[Call to undefined function domxml_open_file()]

This could mean something, or it could not, but

http://us3.php.net/manual/en/function.domxml-open-file.php

says (PHP 4 >= 4.2.1, PECL)  ,  no mention of 5.

Perhaps get PECL.

[Problem With GD Library]

phpinfo() should make some mention of GD.

To evaluate farther, try testing functions

[code]
function test($fxn)
{
  if (function_exists($fxn))
      echo "Yep. I have $fxn <br />\n";
  else
      echo  "No sir-ee Bob, no $fxn for you <br />\n";
}

test('imagecreate');
test('imagecreatefromgif');
test('imagepng');
// test ect..
[/code]

[Ideal directory structure for learning PHP]

It sounds like you have a similar setup than I do on my laptop.

http://localhost/  ==  C:\www\Apache\htdocs

I keep a directory outside of htdocs where I keep htaccess password files and sql connects, but for the most part, htdocs has everything else. How you then setup your site is up to you, but since I have multiple projects with only one address, I have a directory for each.

/htdocs/projectA/

and these generally have the same subdirs

/htdocs/projectA/cls
/htdocs/projectA/css
/htdocs/projectA/js
/htdocs/projectA/docs
and maybe
/htdocs/projectA/tpl

[where (bit & 4)=4 ??]

Very cool.
It also explains why '&&' is used in most php IF statements (returns T/F).


That helped a lot. Thanks!

[where (bit & 4)=4 ??]

I'm support, not dev just so that's clear.
At the workplace, there's a system of flags for users stored as a decimal integer, but represent bits.
0001 means that the first flag is raised therefore the DB stores 1 (person A)
0100 means the same for the third, and stores 4 (person B)
0111 , first three flags raised , so I get 7. (person C)
This I understand, and it's not the problem. We have 50 or so flags and it makes things pretty easy.

What I don't get is the query we use to find out who has what flag raised..
(example structure: id tinytext, bit bigint)

If persons A,B, and C were in the database with the values 1,4,7 above, and I wanted to know who among
them has the third flag raised, we query

select id from persons where (bit & 4)=4;
It returns B, C

To get the first flag,
select id from persons where (bit & 1)=1;
It returns A, C

It works like a charm,  but I can't for the life of me wrap my head around how the query statement finds what I'm looking for. Can anyone explain to me what is going on in "where(bit & 4)=4" ?

Thanks in advance
