Zip a file in php

Recommended Posts

Hello,

 

Anybody there to help!!!

 

I used the code to zip the excel file. It is zipped but got 'file corrupted' message opening the excel after extraction :'(

 

<?php

function uncompress($srcName, $dstName) {

$string = implode("", gzfile($srcName));

$fp = fopen($dstName, "w");

fwrite($fp, $string, strlen($string));

fclose($fp);

}

 

function compress($srcName, $dstName)

{

$fp = fopen($srcName, "r");

$data = fread ($fp, filesize($srcName));

fclose($fp);

 

$zp = gzopen($dstName, "w9");

gzwrite($zp, $data);

gzclose($zp);

}

 

compress("a.xls","a.zip");

uncompress("a.zip","a1.xls");

?>

 

 

Help me!

 

Or any library files are to be included??

Thanks.

 

-Prema
