在使用ZipArchive（）添加到zip之前，如何重命名.txt文件？

Question

I am using ZipArchive() to zip a bunch of .txt files together. Can someone please give me an example how to remove the ID from the beginning of all .txt files before placing them in the zip?

For example:

• 144-apples.txt
• 2-oranges.txt
• 25555-bananas.txt

will be:

• apples.txt
• oranges.txt
• bananas.txt

in the zip.

$name = str_replace(TXT_FILE_DIRECTORY . $group . '/', '', $file);
$zip->addFile($file, $name);

Answer 1

Something like this should work:

<?php
    //Your $files array creation logic here
    foreach ($files as $file) {
        $fileName = preg_replace("/^\d+\-/", "", str_replace(TXT_FILE_DIRECTORY . $group . '/', '', $file));
        $zip->addFile($file, $fileName);
    }
?>

Answer 2

maybe you can serve the following code:

    $this->zipfile->add_dir(FCPATH."files/");
    for($u=$ini;$u<=$do;$u++){
        $this->zipfile->add_file(implode("",file(FCPATH."files/batchsql_".$u.".txt")), FCPATH."files/batchsql_".$u.".txt");
    }

    header("Content-type: application/octet-stream");
    header("Content-disposition: attachment; filename=zipfile.zip");
    echo $this->zipfile->file();
