searching into directory...

[fibonacci]

hi all..

i'm doin a searching function for my website. I learn doin some of the code from the internet and got some it working. Here is my code;

<?php
    error_reporting(E_ALL ^ E_NOTICE);

$keyword = $_POST['keyword'];
$size = 0;
$url = "http://localhost/davinci.html";
$the_page = fopen($url, "r");

if($keyword==""){
    echo"Please enter your keyword";
    exit;
    }

while(!feof($the_page))
{
    $each_line = fgetss($the_page, 255);
    if(eregi($keyword, $each_line, $results))
{
    $size++;
}
}
    fclose($the_page);

print(" <strong>$size</strong> result were found searching for <strong>$keyword</strong> at $url");
if ($size > 0){
    print("<br>Here are your urls to visit:<p><ol>");
    for($index = 0; $index < $size; $index++)
      {
        print("<li>$description[$index] ");
        print("<a href=\"$url\">");
        print("$results[$index]</a></li>");
      }
        print("</ol>");
    }

however, the code above just search the keywords only in http://localhost/davinci.html . I wanted to search a keywords into the directory files. I know how to print out all the files in the directory by using this codes;

<?php

$diary_directory = opendir(".");
  while(
    $filename = readdir($diary_directory))
{
     print("<br>$filename =<strong> ");
     print(filesize($filename));
     print("</strong>");
}
closedir($diary_directory);

?>

but i got stuck when i wanted to merged this two codes, so then my search can search through all files in my directory..
can anyone help me, please

thanks in advanced..

So you want to check is if a word exists in every file within a specified directory and print a list of what files it is found in?

Here you go then. This will scan the contents of a folder ($path) for the keyword ($keyword) and build up a list of the files that contain that word

// Keyword.  Change this if you want to specify it in a URL string etc
$keyword = "";

// Path to search
$path = "path/to_folder/";

// Array to hold matches.  You don't need to define this, but it saves a PHP notice
$matches = array();

if( is_dir($path) ) {
	$open = opendir( $path );
	while ($file = readdir($open)) {
		 if ( is_file($path.$file) ) {
            $content = file_get_contents($path.$file);
            if( preg_match( "/$keyword/i", $content) ) {
                $matches[] = $file;
            }
		}
	}
	closedir($open);
}

print_r( $matches);
