Use zip_open
and zip_read

Documentation to it you can find at http://php.net/manual/en/function.zip-read.php
<?php

function extractZip( $zipFile = '', $dirFromZip = '' )
{
define(DIRECTORY_SEPARATOR, '/');
$zipDir = getcwd() . DIRECTORY_SEPARATOR;
$zip = zip_open($zipDir.$zipFile);
if ($zip)
{
while ($zip_entry = zip_read($zip))
{
$completePath = $zipDir . dirname(zip_entry_name($zip_entry));
$completeName = $zipDir . zip_entry_name($zip_entry);
// Walk through path to create non existing directories
// This won't apply to empty directories ! They are created further below
if(!file_exists($completePath) && preg_match( '#^' . $dirFromZip .'.*#', dirname(zip_entry_name($zip_entry)) ) )
{
$tmp = '';
foreach(explode('/',$completePath) AS $k)
{
$tmp .= $k.'/';
if(!file_exists($tmp) )
{
@mkdir($tmp, 0777);
}
}
}
if (zip_entry_open($zip, $zip_entry, "r"))
{
if( preg_match( '#^' . $dirFromZip .'.*#', dirname(zip_entry_name($zip_entry)) ) )
{
if ($fd = @fopen($completeName, 'w+'))
{
fwrite($fd, zip_entry_read($zip_entry, zip_entry_filesize($zip_entry)));
fclose($fd);
}
else
{
// We think this was an empty directory
mkdir($completeName, 0777);
}
zip_entry_close($zip_entry);
}
}
}
zip_close($zip);
}
return true;
}
// The call to exctract a path within the zip file
extractZip( 'clansuite.zip', 'core/filters' );
?>
