使用PHP删除文件

Question

I have a list of file paths that I want to delete. I placed the file paths in a plaintext file in the root directory of the server. For example:

files_to_be_removed.txt

/path/to/bad/file.php
/path/to/another/bad/file.php

In the same directory, I have another file:

remove.php

$handle = @fopen("files_to_be_removed.txt", "r");
if ($handle) {
    while (($buffer = fgets($handle, 4096)) !== false) {
        if (unlink($buffer))
            echo $buffer . ' removed.';
    }
    fclose($handle);
}

When I run my script, nothing is output. Simply, the files in the list aren’t being deleted. Why is that?

Answer 1

$files = file('files_to_be_removed.txt', FILE_IGNORE_NEW_LINES);
foreach ($files as $file) {
    if (@unlink($file)) {
        echo $file, ' removed', PHP_EOL;
    } else {
        $error = error_get_last();
        echo 'Couldn\'t remove ', $file, ': ', $error['message'], PHP_EOL;
    }
}
