That should solve that problem you have....
This is simplest way, probably to search for a keyword in a page.
PHP Code:
<?php
$file_name=array();
$search_string=$_GET["searchstring"];
$search_result="";
$files=""; $data="";
$link="";
$phpfilename="";
$textstart=0; $textend=0; $strlocation=0;
$numbers=array(5,10,6,8,15,20);
$i=0;
if($search_string!="")
{//ends at last
if ($handle = opendir('name_of_dir'))
{
// List all the files
while (false !== ($file = readdir($handle)))
{
$filename[]= $file;
}
closedir($handle);
}
//read the file get the text and filter the search...
foreach($filename as $value)
{
$files="pages/$value";
$fp=fopen($files,"r") or die("unable to read a file");
$data="";
while(!feof($fp))
{
$data.=strip_tags(fgets($fp));
}
if(strpos($data,$search_string)!=false)
{
$phpfilename=substr($value,0,strpos($value,"."));
$link=$phpfilename.".php";
if($link=="home.php") $link="index.php";
$strlocation=strpos($data,$search_string);
$i=array_rand($numbers);
if(strpos($data,".",$strlocation)!=false)
$textend=strpos($data,".",$strlocation);
elseif(strpos($data," ",$strlocation)!=false)
$textend=strpos($data,".",$strlocation);
else
{
$textend=$strlocation; $strlocation=$strlocation-100;
$search_result.="<p class='contenttext'> <a href='$link'> $phpfilename </a><br />.... "
.substr($data, $strlocation-$i,$textend)."...</p>";
}
}
}
} //if end of if for checking if string is empty
if($search_result!="")
echo $search_result;
else
echo "<br /> No Result found on this search or bad input. <br />";
echo "</div> </div> </div>";
?>
