<?

{ // Code to use if list is in a file
$b = file("script_config.php");
}

$search="default_ccs_style"; // Search string.

echo "<pre>";

$counter=0;
$output="";

foreach ($b as $c) // For each line in the file...
if (strpos(strtolower($c),strtolower($search))!= FALSE) // If it contains the search string...
{
$counter++; // Increment the hit counter.
$output .= " " . trim($c) . "\n"; // Save the info for later.
}

if ($counter) // If the counter was incremented (ie. we have hits)...
echo "Your search returned $counter result(s):\n$output\n"; // Print it out.
else
echo "No hits. =(";

?>

out puts
Your search returned 1 result(s):
$default_ccs_style = './styles/dragon1.css';

now i guess the next step would be to split the string at the =

then how do we read between the "....';
to retrieve ./styles/dragon1.css as our final results?
preg?? (dang if i get how to do preg a regx stuff...i used them in vb.net before but im really bad at making thoses type of matches

hrrrmmm

i got it

<?
function extractBetweenDelimeters($inputstr,$delimeterLeft,$delimeterRight) {
$posLeft = stripos($inputstr,$delimeterLeft)+1;
$posRight = stripos($inputstr,$delimeterRight,$posLeft+1);
return substr($inputstr,$posLeft,$posRight-$posLeft);
}

{ // Code to use if list is in a file
$b = file("script_config.php");
}

$search="default_ccs_style"; // Search string.

echo "<pre>";

$counter=0;
$output="";

foreach ($b as $c) // For each line in the file...
if (strpos(strtolower($c),strtolower($search))!= FALSE) // If it contains the search string...
{
$counter++; // Increment the hit counter.
$output .= " " . trim($c) . "\n"; // Save the info for later.
}

if ($counter) // If the counter was incremented (ie. we have hits)...
echo "Your search returned $counter result(s):\n$output\n"; // Print it out.
else
echo "No hits. =(";
$outputvalue = extractBetweenDelimeters($output,"'","'");
echo $outputvalue;
?>

ill clean the up later igota goto bed and i have a busy day tomorrow so ill clean it up on Monday sometime..

didn't fell you tried to FULLY answer the question.
nor did anyone comment on the fact i figured it out. so i felt you didn't try.

gave more points to raja_ind82, for partially giving an answer
{if you want to get the particular values from the file content, use some delimiter between the set of variables and split in the code after getting the contents from the file.}
wasn't that the point of the question to get the contents from the FILE???
i did not ask for my points back. I felt the question was commented on and should have been answered.
and i wanted others to see the solution.
