Convert file to txt

Question

I had the search on the net but found nothing concerning to do upload of any file and convert it to txt and then do a search for the text you have inside and get results.

Does anyone know how to do what they can do links for me to study the case.

Answer 1

Convert binary files to .txt will not make a search work, each file has its own format.

For each file type you will have to use a method to extract the data and save them in one .txt, some example:

1. XML use http://php.net/manual/en/class.domdocument.php

   Example:

   //Caminho que o seu arquivo xml foi salvo
   $xml = file_get_contents('arquivo.xml');
   $frases = array();
   
   $dom = new DOMDocument;
   $dom->loadXML($xml);
   $books = $dom->getElementsByTagName('*');
   foreach ($books as $book) {
       $frases[] = $book->nodeValue, PHP_EOL;
   }
   
   //Salve o $vetor em um txt, assim:
   file_put_contents('arquivo.xml.txt', implode(' ', $frases));
   

2. CSV use http://php.net/manual/en/function.fgetcsv.php

   //Caminho que o seu arquivo xml foi salvo
   $handle = fopen ("arquivo.csv", "r");
   $frases = array();
   while (($data = fgetcsv($handle, 1000, ",")) !== FALSE) {
       $frases = array_merge($frases, $data);
   }
   fclose ($handle);
   
   file_put_contents('arquivo.csv.txt', implode(' ', $frases));
   

3. XLS will probably have to use a library to facilitate how https://code.google.com/p/php-excel-reader/ or http://sourceforge.net/projects/phpexcelreader/

These are just a few examples, for each format you implement in your application you will have to use a new script.

I believe that there is no "magic" solution ready for this, you will have to take what exists and create an application based on this.

To make the appointment, let’s assume that you saved everyone .txt in a folder, then you should do a search similar to this:

$consulta = 'Palavra';
$arquivos = array();

if ($dh = opendir($dir)) {
    while (($file = readdir($dh)) !== false) {
        if (is_file($dir . $file)) {
            $data = file_get_contents($dir . $file);
            if (stripos($data, $consulta) !== false) {
                 $arquivos[] = $file;
            }
        }
    }
    closedir($dh);
}

echo 'A consulta "', $consulta, '" encontrou ', count($arquivos), ': ', implode(', ', $arquivos);

Answer 2

I’m not sure I understand your question, but if you want the list of files listed in a txt file, use the following command:

exec( "dir $diretorio /s > $NomeArquivo.txt" );

I hope I’ve helped.
