Hi,

I'm having a problem with a class, im using foreach but if I put the include in the foreach I get an error. Also when I do get it to work, it keeps loading, loading & loading.

I hope someone can help me, my code:

<?php
/* You can put this in other file and just include it */
function OpenDb($hostname,$uid,$pwd,$dbname){
$link = @mysql_pconnect($hostname,$uid,$pwd);
if($link && mysql_select_db($dbname)){
return($link);
}
else{
return(FALSE);
}
}
?>
<?php
// It may take a whils to crawl a site ...
set_time_limit(10000);




function QueryIntoArray($query){
        settype($retval,"array");
        
$result= mysql_query($query);
        if(!$result){
print "Query Failed";
        }        
        for($i=0;$i<mysql_numrows($result);$i++){
                for($j=0;$j<mysql_num_fields($result);$j++){
                        $retval[$i][mysql_field_name($result,$j)] = mysql_result
($result,$i,mysql_field_name($result,$j));
                }//end inner loop
        }//end outer loop
return $retval;
}//end function
?>

// for testing we dont want to "suck" the whole site)
$crawler->setTrafficLimit(9999999999999999999 * 99999999999);

// Thats enough, now here we go
$crawler->go();


// At the end, after the process is finished, we print a short
// report (see method getReport() for more information)

see this?

 

while ($line = mysql_fetch_array($result, MYSQL_ASSOC)) {
    foreach ($line as $col_value) {



// Inculde the phpcrawl-mainclass
include("classes/phpcrawler.class.php");

 

as you can see you have your class file in a loop

 

you only need it once so place it outside your loop

from a class you can create an object and putting the class file in a loop is pointless thast why you get the error cant redeclare class
