Re: [PHP] Form Name Attribute Help!

[Chris Hobbs]

It doesn't appear that the name attribute is passed (ref: 
http://www.blooberry.com/indexdot/html/tagpages/f/form.htm). Instead, 
try including the following in each of your forms:



Then you can check $formname in file.php for the value.

Hope this helps!

Re: [PHP] Eval()??? A variables contents?

[Chris Hobbs]

I just asked a similar question yesterday. The answer is, conveniently
enough, eval().

One trick from the php.net page on the function is to do somehting like
this:

$content = "";
echo eval ("?>$content");

OK, maybe I'm missing something, but why not just replace:

Assuming your Query_Database() function returns a string, this should
work fine.

Re: [PHP] Variable definitions...

[Chris Hobbs]

Hi Stephan,

IMHO, I think the answer requested is the only one that really makes 
sense - as soon as I read it, _my_ first thought went to scope.

If a variable changes values, the other value is no longer usable, and 
thus there aren't really two variables with the same name in that case. 
When comparing global to local scope, however, you can definitely have 
the same name in use in two places.

Of course, I wasn't a CS major, so someone else might be able to give 
you an answer that will help you justify yours - but prima facie, you 
got it wrong :(

Now, if you're talking about the compiler level, then no two variables 
(which are actually memory registers at this point, iirc) can share the 
same memory space with different values - this is just logically 
impossible. But the question is certainly referring to source code, and 
so scope is the only reasonable answer.

HTH!

Re: [PHP] url exist?

[Chris Hobbs]

Looks like you might be able to use the cURL extensions 
 - there's a function called 
curl_getinfo which returns an array which includes http_code - you could 
check the value of that to see whether the file was available (http_code 
== 200), not found (http_code == 404), or whatever 
().

Have fun!

Re: [PHP] Very interesting and challenging question

[Chris Hobbs]

A fellow wannabe Winston Cup driver :)
 
I'm thinking about setting a switch on $mode, which will change what it 
does based on the value of $mode. Something like this:

$mode = 1; // 1 for stripping text, 2 for adding driver results, 3 for 
adding race results
$file = file('/path/to/filename');
foreach ($file as $line) {
switch ($mode)  {
case 1: if (preg_match("/^ *[0-9][0-9]*  */", $line)) {
   $mode = 2;
   // split line up with explode() and enter it into db  
  }
break;
case 2: if (!preg_match("/^ *[0-9]* */", $line)) {
   $mode = 3;
} else {
// split line up with explode() and enter it into db
}
break;
case 3: if (preg_match("^[a-zA-Z#]*") { // avoid matching blank 
lines
// do whatever to put these into a INSERT query...
}
}
}

So in mode 1, it merely loops through lines until it finds one with zero 
or more spaces followed by one or more numbers followed by one or more 
spaces. When it hits one of those, it breaks that line apart and enters 
it into the db, then sets $mode to 2.

In mode 2, it continues to loop through looking for the same lines until 
it doesn't get a match, then sets mode 3.

Mode 3 looks for lines starting with text (skipping blank lines). It's 
left as an exercise for the reader to figure out how to get those values 
into the db :)

Hope this helps!

Intersting. I tried the following code (which gives much more detailed 
time info, check it out - stolen from Andrey Hristov on php-db), and my 
times, on our P2-266 webserver, are just above 9 seconds. That's at 
2000x2000 iterations, or 4M iterations.

Of course, I'm trying to figure out when I would have a script that 
really needed to go through 4M iterations, and thus (like most 
benchmarks) this probably has no real bearing on the (or at least my) 
real world.

Or, mysqlimport is not in the path - try using the complete path and see

Looking at the docs (I know, silly, eh?), the correct form of this

A couple of things:

First, I believe Location: must have a space after it, as well as a 
fully qualified URL (ie. http://wherver.com/index.php).

Second, once you've sent the Location header to the browser, I would 
expect it to immediately request the new page, and therefore not get the 
cookie you send afterwards. Why not just set the cookie in index.php?

If you can live without realtime, one way of handling this is to have 
the httpd user write out a file with commands to be run, and a root cron 
job (set to run as frequently as every minute) watch for that file and 
act upon it when it exists. Obviously, there would be some lag, but it 
would be one way to handle the security side of this issue.

You want to see something really weird? Try using 'MORON' instead of 
'NYC'. It doesn't actually mean anything, but at least you'll have a 
signature you can start using if you're going to keep posting this tripe...

[PHP] Problem recursively building array

[Chris Hobbs]

I'm attempting to build an array of filenames in a sub-directory with 
sub-directories. I'm using a modified version of code found on php.net - 
the function I wrote is here:

function getDirList ($dirName) {
 $dirList=array();
 $d = dir($dirName);
 while ($entry = $d->read()) {
 if ($entry != "." && $entry != "..") {
 if (is_dir($dirName."/".$entry)) {
 echo "Directory found: $entry\n";
 $dirList = $dirList + getDirList($dirName."/".$entry);
 } else {
 $temp = $dirName."/".$entry;
 $temp = str_replace("/var/www/html/boarddocs/", "", $temp);
 echo $temp."\n";
 $dirList[] = $temp;
 }
 }
 }
 return $dirList;
}

It's called with: $bplist = getDirList($bppath);
$bppath is correct.

The problem is that although my testing of the function shows all of the 
entries correctly (note the 'echo $temp' line), not all of these entries 
are ending up in the array - in fact, large chunks of some directories, 
and all of other directories, are missing.

Sample output is here: http://www.silvervalley.k12.ca.us/boarddocs/bpar.php

Complete code is here: http://www.silvervalley.k12.ca.us/boarddocs/bpar.phps

I'm gonna be real annoyed if I missed something stupid. I built as much 
debugging output into this as I thought I should, but your help will be 
appreciated.

OK, on a lark I changed the above to use array_merge, and the problem 
went away - that'll teach me to use a shortcut :)

Exactly why I switched our site from '/index.php?page=1' to 
'index.php/1' - google and other search engines love following my links 
now :)
