Value of variable to increment

ducey

Hi,

I am writing a script to analyse my access log file. And I'm stuck on one area.

I have read a line in, exploded it to retrieve the page that was visited, and now need to increment the relevant counter related to that page.

This is what I have so far:

// Establish the variables
$file = "access.log";
$handle = fopen($file,"r");
$page;
$counter = 0;
$pageArray = array();
$homePage = 0;
$welcomeCounter = 0;
$searchCounter = 0;


while(! feof($handle))
{
	// Now do the processing on each line returned
	$line = fgets($handle, 1024);
	$text = explode(" ",$line);
	$page = $text[10];
	// Strip the exact page from the variable $page
	$exactPage = explode("=",$page);
	$visitedPage = $exactPage[1];
	// Remove the last character of the string
	$visitedPage2 = explode("&",$visitedPage);
	$visitedPage = $visitedPage2[0];
	// Count the number of visitors by getting the page name, appending 'Page' to the end of it and incrementing the respective counter o_0
	$visitedPageCounter = $visitedPage . "Page";
	$visitorPageCounter;
	//$visitedPageCounter++;
	$counter++;
}

It is the last few lines that I am stuck on. The value of $visitedPage for example, is 'welcome' (without the quotes) and then I have added 'Page' to the end of it to get 'welcomePage' as the value of $visitedPageCounter.

Now I want to get the value of $visitedPageCounter and increment it. I don't fancy writing long IF and ELSEIF statements to compare the value of it, so is there a way I can retrieve the value of $visitedPageCounter and to have the code '$welcomePage++' ?

Thanks,

Nathan

${$visitedPageCounter}++;

[edit]
Actually, it would be better to use an associative array like so.

$visited_count[$visitedPageCounter]++;

The reason I say this is because it would make life much easier for iterating through the list afterwards for further processing (which I imagine will need to be done), you'll just need to use a foreach.

Thanks very much bubblenut 🙂
It works a treat!

But what exactly do the '{' and '}' mean?

Check out the php manual on Variable variables

Thanks again.

I'll take a look at the page you linked to.

I did think about an array, but the last time I wrote a script liek this, I used a lot of arrays and brought the server down because it used the entire virtual and physical memory!!! :queasy:

So i'll not be using them as extensively as before, but I agree, they would make things easier 🙂
