<?php

$stringData='';

$stringval=0;

if ($_GET['q']){

$stringData=$_GET['q'];

$stringval +=$_GET['offset'];

}

$stringData=trim($stringData);



function get_value_of($name)

{

     $lines = file('config.txt');



     foreach (array_values($lines) AS $line)

     {

          list($key, $val) = explode('=', trim($line) );



          if (trim($key) == $name)

          {

                return trim($val);

          }

     }

     return false;

}



$base_url= get_value_of('BaseUrl');





?>

look at this..

$output .= shell_exec("search.pl $stringData $stringval");

if any variable has blank value then it create problem so i need to call this only when both variable have some value.....

and one more thing look at this latest part of code

PHP Code:


			
<?php

$output = '<?xml version="1.0" encoding="ISO-8859-1"?>';

$output .='<?xml-stylesheet type="text/css" href="my_css.css"?>';

$output .= shell_exec("search.pl $stringData $stringval");

//exec('search.exe "$stringData" "$stringval"',$output);

//echo $output;

$dom=new DOMDocument();

$dom->LoadXML($output);

$root = $dom->documentElement;

//echo $root->nodeName;

$report='';

if ($root->hasChildNodes())

{

 $children = $root->childNodes;

     foreach($children as $node)

     {

          

          //print $node->nodeName."\n";

          if ($node->nodeName=="Result")

          {

               if ($node->hasChildNodes())

               {

                    $element=$dom->getElementsByTagName("Result");

                    $report .= '<p>

                    <a href="$element->item(URL)->nodeValue"><strong>$element->item(Title)->nodeValue</strong></a>

                    <em>$element->item("Score")->nodeValue</em>

                    <br>

                    $element->item("BodyText")->nodeValue

                    <br>

                    <span class="excerptURL">$element->item("URL")->nodeValue</span></p>';

                    print $report;

                   

               }

               else

               {

                  $report .='<p>"$node->nodeValue"</p>';  

               }

          }

          else

          {}

        

     }

}

?>

after getting the xml in return i will parse it in this way and then i will convert it in html paragraph so that also creating problem...
Thanks

the code nico_swd and i said will do:

PHP Code:


			
$stringData = trim($stringData);

$stringval = trim($stringval);

if(!empty($stringData) && !empty($stringval)){

// place your code here

}else{

  echo"empty input";

}

what are the output problems you're having atm?
