PHP search function on website. (easy) - php

Question

I have implemented a php search function on a clients website. What I would like it to do is search for files within the website directory for specific pdf files.
However I can't seem to get it to work. If I type in "pdf" into the search box it returns all the files in the directory but if I put in a specific file name then it returns nothing.
Below is the php script I am using:
<?php
$my_server = "http://www.gwent.org".":".getenv("http://www.gwent.org_80");
$my_root = getenv("docroot/");
$s_dirs = array("");
$hits = null;
$full_url = $_SERVER['PHP_SELF'];
$site_url = eregi_replace('customer_information.php', '', $full_url);
$directory_list = array('sold_msds');
$s_files = ".pdf";
foreach($directory_list as $dirlist)
{
$directory_url = $site_url.$dirlist."/";
$getDirectory = opendir($dirlist);
while($dirName = readdir($getDirectory))
$getdirArray[] = $dirName;
closedir($getDirectory);
$dirCount = count($getdirArray);
sort($getdirArray);
for($dir=0; $dir < $dirCount; $dir++)
{
if (substr($getdirArray[$dir], 0, 1) != ".")
{
$label = eregi_replace('_', ' ', $getdirArray[$dir]);
$directory = $dirlist.'/'.$getdirArray[$dir]."/";
$complete_url = $site_url.$directory;
if(is_dir($directory))
{
$myDirectory = opendir($directory);
$dirArray = null;
while($entryName = readdir($myDirectory))
$dirArray[] = $entryName;
closedir($myDirectory);
$indexCount = count($dirArray);
sort($dirArray);
}
else
{
$hits++;
if(file_exists($dirlist."/".$label))
{
$fd=fopen($dirlist."/".$label, "r");
$text=fread($fd, 50000);
$keyword_html = htmlentities($keyword);
if(!empty($keyword))
{
$do=stristr($text, $keyword) || stristr($text, $keyword_pdf);
}
if($do)
{
$strip = strip_tags($text);
$keyword = preg_quote($keyword);
$keyword = str_replace("/","\/","$keyword");
$keyword_html = preg_quote($keyword_html);
$keyword_html = str_replace("/","\/","$keyword_html");
echo "<span>";
if(preg_match_all("/((\s\S*){0,3})($keyword|$keyword_html)((\s?\S*){0,3})/i", $strip, $match, PREG_SET_ORDER));
{
$number=count($match);
if($number > 0)
{
echo "<a href='".$dirlist."/".$label."'>".$label."</a> (".$number.")";
echo "<br />";
}
for ($h=0;$h<$number;$h++)
{
if (!empty($match[$h][3]))
{
printf("<i><b>..</b> %s<b>%s</b>%s <b>..</b></i>", $match[$h][1], $match[$h][3], $match[$h][4]);
}
}
echo "</span><br /><br />";
if($number > 0):
echo "<hr />";
endif;
}
}
}
}
}
}
}
?>
Many thanks In advance

Answer 1

Look up the glob function http://php.net/manual/en/function.glob.php
$found = glob("/path/to/dir/*.pdf");
Edit: Nevermind your question makes it sound completely different to what your code is doing. Im guessing what i posted is incorrect

Answer 2

Simple search, this is not recursive. Give it a directory and it will spit out the found files
$files = glob("c:/xampp/htdocs/*.php");
if(empty($files)) {
echo "No PHP Files Found";
}
else {
foreach($files as $f) {
echo "PHP File Found: ".$f."\n";
}
}
