[PHP] Getting Numerical Index of a Key
Is there an easy way to get the numerical index of a text key for an array? I don't see anything in the manual, but before I waste time writing code to find this info, I thought I would double check here. ---Matt
RE: [PHP] Getting Numerical Index of a Key
Because I created it with mysql_fetch_array(). I know for a fact that both keys exist, and I can look at the output and tell what text key matches to what numerical key, but I don't want to hardcode it like that. The people that are taking over this code might change something and screw everything up. ---Matt -Original Message- From: Leif K-Brooks [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 04, 2003 12:35 AM To: Matt Honeycutt Cc: [EMAIL PROTECTED] Subject: Re: [PHP] Getting Numerical Index of a Key What makes you think it HAS a numerical index?

RE: [PHP] Getting Numerical Index of a Key
Bad design, basically. This script is creating the array, then modifying a certain value in it using the text key. Later, it's referring to each value in the array by numerical index. Apparently, the text key and the numerical index do not refer to the same values in PHP, so the value it's referring to with the numerical index is the original value, not the one that was modified. I'm just going to spend the extra 5 minutes and rewrite that little chunk of code. ---Matt -Original Message- From: Leif K-Brooks [mailto:[EMAIL PROTECTED] Sent: Tuesday, March 04, 2003 12:39 AM To: Matt Honeycutt Cc: [EMAIL PROTECTED] Subject: Re: [PHP] Getting Numerical Index of a Key No, there's no easy way to do this.

RE: [PHP] re: strip comma from $value
ereg_replace returns a string, regardless of whether or not any replacement
occured. If no replacement occurs, the original string is returned.
Additionally, it does not modify the original string, so you need to store
the string it returns:
foreach($numeric_array as $key = $value ) {
if(strstr($value,,))
{
$value = ereg_replace(,,,$value);
echo comma stripped);
}
}
Give that a shot and see if it works (I didn't test it, but it should).

Hi,
Trying this:

foreach ($numeric_array as $key = $value) {

Does the same thing as before, echo's comma stripped, but does not
actually remove the commas

RE: [PHP] re: strip comma from $value
I'm sorry, I missed a really big problem with what you're doing.
When you use foreach(), the value that it gives you (in your case, via the
$value variable) is not a reference to the array item, its a copy of it, so
modifying the copy doesn't modify your original array.
Use this (this should work):
for($i=0; $i size($numeric_array); $i++) {
if(strstr($numeric_array[$i],,))
{
$numeric_array[$i] =
ereg_replace(,,,$numeric_array[$i]);
echo comma stripped;
}
}
Give that a shot and see what happens...

asort ($numeric_array, SORT_NUMERIC);
I've tried this but it looks like it's having problems with the comma in
big numbers.
I'm not absolutely sure, but it looks like it's ignoring everything
after a comma when it sorts.
BTW: asort is the one I need as I must maintain the keys

Hello Mike,
You will need to better describe your problem and preferably show some

What characters are being added to it? You could use str_replace or the
regular expression replacement functions but you should not get added
characters in general.

[PHP] Another Logging Question
I'd like for my counter/logger to be fairly scalable, so I'm toying with two possible implementation routes: 1. Have the counter dump visitor info to a text file, then run a cron job on that nightly to process the data and perform a full analysis. 2. Have the counter dump the visitor info into a DB (probably MySQL), then process the data whenever the administrator wants to view his stats. Anyone have any suggestions or considerations on which method would work better? Is there something else I should do instead?

RE: [PHP] Another Logging Question
Right now, it's logging the client's IP, the page that they're viewing, the page that they came from, the time of the visit, and their system and browser info. I think I'm going to go with a database to store the information, but do a mixture of long term and short term storage. I think I'll add an admin command that causes it to go through and generate statistics from the unprocessed data that's been collected, then move that data to a flat, compressed file for archiving purposes and just store the summary information. Ideally, processing of the raw data would only be performed as needed (and infrequently), so the majority of the database interaction would be inserts. Wow, that was a mouth full. I'd like to have the counter on each page of my site, and (hopefully) it will be getting quite a few hits. I still think the database will probably be the best way to go though as it keeps me from having to even think about file locking issues. ---Matt -Original Message- From: Justin French [mailto:[EMAIL PROTECTED] Sent: Sunday, February 23, 2003 5:12 PM To: Matt Honeycutt; Php-General Subject: Re: [PHP] Another Logging Question on 24/02/03 3:30 AM, Matt Honeycutt ([EMAIL PROTECTED]) wrote: I'd like for my counter/logger to be fairly scalable, so I'm toying with two possible implementation routes: what are you logging (what kind of data) 1.

Have the counter dump the visitor info into a DB (probably MySQL), then process the data whenever the administrator wants to view his stats. On-demand stats will use up more space long-term than generating monthly reports or something... but there are obvious benefits. The biggest issue IMHO is that if your site is processing a large amount of data, processing it over and over and over on demand is going to burden the server. Anyone have any suggestions or considerations on which method would work better? Is there something else I should do instead? If you're going to be dealing with large amounts of data, a combination. Perhaps perform a monthly analysis and consolidation of data to keep on demand / real time processing to the current month only... However, make sure you keep the long-term data SOMEWHERE, in case you want to change the reporting, method, or analyse the data a different way. If we're only talking about a counter on a few pages, real-time should be fine.

RE: [PHP] Another Logging Question
Yeah, I know, but I'd like this counter to provide that functionality for those that don't have access to Apache's logging capabilities (either because their hosts don't allow it or because of the platform they're being hosted on). At some point, I'd like to provide a toggle to have the counter grab statistics directly from Apache's logs, but that's going to be much later on after I finish up some other projects. ---Matt -Original Message- From: David Freeman [mailto:[EMAIL PROTECTED] Sent: Sunday, February 23, 2003 5:44 PM To: 'Php-General' Subject: RE: [PHP] Another Logging Question Right now, it's logging the client's IP, the page that they're viewing, the page that they came from, the time of the visit, and their system and browser info.

[PHP] Logging Referer
Hi all, I'm working on adding some logging functionality to a PHP image counter script that I wrote. The counter outputs an image representing the current number of hits and is used via an img tag. After it displays the image, the counter collects information about the user (browser version and OS, date and time of visit, ip, etc). I'd also like for it to log the referer, but because the counter is triggered via an img tag, the referer is always the page that has the img tag. Is there any other way to grab the referer that actually sent the user to the page that contains the counter? I'd like for the counter to work even when included in static HTML pages, so the including page cannot use any PHP to help facilitate this logging functionality. I hope all that makes sense.

No, not easily :) On PHP pages, you could get the referrer, and append it to the URL, forcing the correct REFERRER through to the img script: img src=makeMyCounter.php?ref=?=$_SERVER['HTTP_REFERRER']? And you *could* choose to force .html files through the PHP parser, so foo.html could use the above code. I think the other alternative is to use javascript to build the img tag, because I'm pretty sure JS can figure out the referrer. But this has the obvious downside of JS being NO WHERE NEAR guaranteed to be on each browser. I think i'm missing something though, because I *think* those free counter/stat programs DO log a referrer... wait -- just checked thecounter.com, and they DO use JS for the referrer.
