Question: I try to read all `*.txt` files from a folder and write all content from each file into another txt file. But somehow it only writes one line into the txt file.

I tried with `fwrite()` and `file_put_contents()`, neither worked.

Here is my code: 

```
<?php

    $dh = opendir('/Applications/XAMPP/xamppfiles/htdocs/test/');

    while($file = readdir($dh)) {
        $contents = file_get_contents('/Applications/XAMPP/xamppfiles/htdocs/test/' . $file);
        $dc = array($contents);   
    }

    file_put_contents('content.txt', $dc);

?>

```

Answer: 
This should work for you:

(Here I get all \*.txt files in a directory with [`glob()`](http://php.net/manual/en/function.glob.php). After this I loop through every file with a foreach loop and get the content of each single file with [`file_get_contents()`](http://php.net/manual/en/function.file-get-contents.php) and I put the content into the target file with [`file_put_contents()`](http://php.net/manual/en/function.file-put-contents.php))

```
<?php

    $files = glob("path/*.txt");
    $output = "result.txt";

    foreach($files as $file) {
        $content = file_get_contents($file);
        file_put_contents($output, $content, FILE_APPEND);
    }

?>

```
try this 

```
$contents = array();
$line = file(/*next file in dir*/);
foreach($lines as line){
   array_push($line, $contents);
}
//File path of final result
    $filepath = "mergedfiles.txt";

    $out = fopen($filepath, "w");
    //Then cycle through the files reading and writing.

      foreach($filepathsArray as $file){
          $in = fopen($file, "r");
          while ($line = fgets($in)){
                print $file;
               fwrite($out, $line);
          }
          fclose($in);
      }

    //Then clean up
    fclose($out);

    return $filepath;

```
