[PHP] Re: Count and Preg_Replace Using Version 4.4.1

Hi,
The following code matches all occurences of tags within an html page
and wraps form tags around it:
echo preg_replace(
'/]*>(.*?)<\/p>/ms',
'action="'.$CFG->edit_pages_adm.'/index.php?action=edit_paragraph"
method="post">
$1
',
file_get_contents($CFG->frontenddir_editable.'/'.$file) );
Unfortunately if there is more than one match the form won't submit because
the forms have the same name. Does anyone know how can I modify this so that
each occurence is numbered sequentially i.e.
form'.$count.'...
As I am using version 4.4.1 I don't have access to the count paramter in
version 5.1.
Thanks for your advice
Each of your html input elements must have a different name, otherwise the php
code will only see the last one.
Consider a simple foreach loop to generate your html input elements, e.g.,
$report= ""; $i= 0;
foreach($array as $key=> $value){
$report .= "";
other stuff as needed
$i++;
}//end
echo $report;
I'm not sure I see why you need the JAVA script. Seems like you can let the user poke in everything and then provide a
submit button to post everything.
Your $_POST will contain all the results. e.g.,
$value1= $_POST['input1'];
$value2= $_POST['input2'];
etc.
Another simple foreach loop can be used to extract the input values.

Hi Mike, There is no surefire way to measure the exact time a user leaves your site. The most accurate way I can think of would be to use a hidden frame on all your pages that refreshes itself every X seconds. When a user has not requested that special tracking page for more than X seconds, you can assume they have 'left' the site. However this solution seems like overkill for most purposes: you'll be wasitng server resources and slowing down your users' experience on your site. In response to your proposed method, most advertising associations (including the US-based Internet Advertising Bureau) and web analytics companies (such as Red Sherrif, Nielsens and Hitwise) define the end of a user session on a website when there is 30 minutes without a further request for a page from the site. And while you may be tempted to track only IP numbers, remember that many users are behind shared IP numbers (e.g. firewalls) which may skew your stats. You would be better off using cookies on user's machines to identify them and log their accesses to a DB.

If you're using MySQL - I don't know if COUNT() is a part of SQL'92 - you
can use SELECT COUNT(*) FROM table like this:
The two zeros at the end means that mysql_result is to fetch the first row,
the first column of the result.
(Also, it'll be much faster than mysql_num_rows(mysql_query("SELECT * FROM
table"))

Are there other people/pages/process that are altering the 'active' state of
categories?
Because it's entirely possible that while the script below is only HALF
finished, somebody else comes in and alters the data out from under you.
Which means that your results will "seem" to be incorrect, since the state
of the world changed mid-stream.
You may want to use:
mysql_db_query($db, $query) or error_log(mysql_error());
instead of all those lines you have to comment/uncomment all the time.
When things go wrong, it will be in your Apache error_log
You may also be getting confusing results if some records has Category1 =
'foo' and Category2 = 'foo' It's going to get "double-counted" in the
current algorithm.
If it's none of the above, you'll *have* to do some digging to figure out
what causes the 0.1% of the time...

Don't think you *CAN* be 100% certain the download succeeded...
You can dink around with ignore_user_abort (or not) and friends to *maybe*
improve accuracy, but you'll never get 100%...

[PHP] RE: Count columns in array
it's important to remember that what you have here is NOT a 2d array. $array is an array, each element of which can be any sort of variable ... e.g. $array[1] = "fred"; $array[2] = Array(); $array[3] = 1.245; ... but then try ... foreach ($array as $thisarray) echo(count($thisarray) . ""); ... in this case count($array[2]) = 0 but count($array[1]) = 1 ... so be careful.
