Question

So my problem is this I got a code that loops trough a loggfile then compares them to a treestructure and then gives them a id that correspond to the id in the structure. To not get a lot of bad traffic i sort out all the 302 and above.

The problem is now that i want some specific 302s to count that have a particular pagetype in the structure. This is not a big problem as I can just match the url in the loggfile against the url in the tree structure but some loggfiles does not use friendly url while the structure is in friendly url this creates a problem but I can just match the id in the query parameter with the id in the structure. I then make a string of all the ids that match the special pagetype that I want.

The problem is this I can not get the Mysql statement to work, it looks like this.

$sqlQ1 = "SELECT `lid` FROM logfile WHERE date = '$date' AND ´query´ IN '$check'";

A example query can look like this “id=4&epslanguage=sv” so I want to check only the id=X part.

It´s a kinda easy question really im just stuck and can not get it to work, any help is appreciated!

Answer 1

I think your Q is: How do I extract id from that part of a line?

“.. so I want to check only the id=X part.”

Once you have isolated that string then you can use:

$string = "id=4&abclang=sv";

parse_str($string);

echo $id; // 4

EDIT
In light of other responses:

$strings[] = "id=4&abclang=sv";
$strings[] = "id=45&abclang=en";

$vals = array();

foreach( $strings as $string){
parse_str($string);
$vals[] = $id ;
}

$in_clause = join(",", $vals) ;
 $sql = "SELECT lid FROM logfile WHERE something  IN ($in_clause) ";
echo $sql; // SELECT lid FROM logfile WHERE something IN (4,45)
