读取特定文件夹中的所有txt文件，并将所有内容写入一个txt文件中

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 1

This should work for you:

(Here I get all *.txt files in a directory with glob(). After this I loop through every file with a foreach loop and get the content of each single file with file_get_contents() and I put the content into the target file with file_put_contents())

<?php

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

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

?>
