Associative Arrays

Posted: Wed Feb 09, 2005 10:51 pm

I'm stuck. What I'm trying to do is create a simple log analyzer that reads in an apache log, grab the IP address and time stamp, and then summarize the number of hits per IP per time (or whatever format).

I can grab the information just fine but I'm getting stumped on building the array.

Here's what I have:

Code:

$fp = fopen( $filename, "r" ) or die ("Couldn't open $filename for read!\n");





   while ( ! feof( $fp )) {


      $entry = fgets( $fp );


      preg_match( '/^(.*?)\s.*?\[(.*?)\s/', $entry, $first2 );

Inserting a print_r on $first2 gives this type of ourput:

Code:

Array


(


    [0] => 199.0.204.204 - - [30/Jan/2005:08:26:03 


    [1] => 199.0.204.204


    [2] => 30/Jan/2005:08:26:03


)

That is what I want but I need to build an array using first2[1] and [2].

Would someone kindly nudge me in the right direction?

Thanks.

Not sure I'm tracking here. If $first2 is comprised of $first2[0], [1], and [2], then just have a statement after that like

$newArray[0] = $first2[1];
$newArray[1] = $first2[2];

or, to build an ongoing array that you will later parse by every 2 statements,

$newArray[] = $first2[1];
$newArray[] = $first2[2];

Since that sems way too simple, that's probably not what you want.

That will work for now but if I add more elements, such as referrer, browser agent, etc, it could get a little tricky sorting and such.

Maybe I should build the array with all the apache log elements in the array and then only load what I want to see...

Code:

$log = array ( 


               array (


                  'ip'=>"",


                  'date'=>"",


                  ,request_type'=>"",


    ...etc...     )


          )

I wonder how I could dynamically populate this kind of array?
