u need to add header for the client about file downloading. just see the manual example: http://php.net/manual/en/function.header.php#example-5315

<?php
    $file = getcwd() . '/read.zip';
    // http headers for zip downloads
    header("Pragma: public");
    header("Expires: 0");
    header("Cache-Control: public");
    header("Content-Description: File Transfer");
    header("Content-type: application/octet-stream");
    header("Content-Disposition: attachment; filename=\"read.zip\"");
    header("Content-Transfer-Encoding: binary");
    header("Content-Length: ".filesize($file));
    ob_end_flush();
    @readfile($file);

I have tried the above code. but still its not working. I'm just a beginner. Can u please help me more? – Jay Feb 06 '18 at 12:20
I have added this headers after $zip->close(); – Jay Feb 06 '18 at 12:21
@Jay, sorry! I've just missed the main thing - readfile($file); – myxaxa Feb 06 '18 at 12:49
It generates o/p like........ PK�bFLOm:�/newname.txtHello I'm in reading mode.PK�bFLOm:��/newname.txtPK:Dok........ But not still downloading zip automatically – Jay Feb 07 '18 at 08:31
just a moment, I'll check it localy – myxaxa Feb 07 '18 at 08:54
okay I'm not getting any trouble in downloading text file by adding header().. But here I am getting strange o/p as I mentioned above. – Jay Feb 07 '18 at 10:28
is the zip file created? – myxaxa Feb 07 '18 at 11:01
well, remove the "echo" and try again – myxaxa Feb 08 '18 at 14:06
didn't you forget $zip->addFile(getcwd() . '/read.txt',getcwd() . '/newname.txt'); near the newname.txt? – myxaxa Feb 08 '18 at 14:19
Yeah I removed echo and tried but still its not working. Even I also add getcwd() before newname.txt but though its not working. It generates the output as I told u before like this..... PK�bFLOm:�3/Applications/MAMP/htdocs/Jay/php/exam1/newname.txtHello I'm in reading mode.PK�bFLOm:�3��/Applications/MAMP/htdocs/Jay/php/exam1/newname.txtPKak....... as I add getcwd() before newname.txt so it produced newname.txt code in the file as well but not downloading. – Jay Feb 09 '18 at 07:22
btw I'm using MAC but I don't think that its an OS problem. – Jay Feb 09 '18 at 07:23
