I'm trying to extract the contents of a zip package to a specific folder and keep getting an error.  I know the .zip package is good as I can open in from other programs.  This is php 5.2 so I know ZipArchive class is bundled.  Help???
Private $extractDir = './IMG/';

Private function download_pics ($dl_link){
	$zip = new ZipArchive;
	echo ('<br/>Start d/l Function');
	if  ($zip->open('./Test.zip') === true){
	  echo ('<br/>Start 1st Zip');
	  $zip->extractTo($extractDir);
	  $zip->close();
	  } ELSE {
  	  die("<br/>There was a problem unpacking the website .ZIP archive.");
	  }
  echo ('<br/>End Zip Functions');
  }

I searched my php.ini and could not find a reference to php_zip.dll,  there was a mention of zlib but that appeared to be for uploading files.

I added:

extension=php_zip.dll

Still getting error, do I need to reboot?  Let IIS sit for 30 minute but did not restart services.

I have Error logging set to on and production level put nothing appeared but the error built into the code.

You need to restart the IIS,

You can verify the ZI functions are loaded, creating a file with
<?
echo phpinfo();
?>

And run it from internet explorer,
This show a list, with the status of PHP
and all the loaded plugins, here must be the ZIP libraries showed

I worked with this function to extract without problems:

function extractZip( $zipFile = '', $dirFromZip = '' )
{
	define(DIRECTORY_SEPARATOR, '/');    
	$zipDir = getcwd().DIRECTORY_SEPARATOR;
	$zip = zip_open($zipDir.$zipFile);    
	$zipDir = getcwd().DIRECTORY_SEPARATOR;
	if ($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;
}

That is nice.  I don't need to enumerate through the ZIP file, just expand the contents to a folder.  The code below is directly off the PHP Website but still the ZIP file fails verification somehow.  I know the zip is valid, as I can open in numerous archiving application but it still fails the boolean test.
<?php
$zip = new ZipArchive;
if ($zip->open('test.zip') === TRUE) {
    $zip->extractTo('/my/destination/dir/');
    $zip->close();
    echo 'ok';
} else {
    echo 'failed';
}
?>
