ZipArchive::deleteName
I am using this function to extract a specific folder and it's contents from a zip file:
<?php
function extractDir($zipfile, $path) {
if (file_exists($zipfile)) {
$files = array();
$zip = new ZipArchive;
if ($zip->open($zipfile) === TRUE) {
for($i = 0; $i < $zip->numFiles; $i++) {
$entry = $zip->getNameIndex($i);
//Use strpos() to check if the entry name contains the directory we want to extract
if (strpos($entry, "/MyFolder/")) {
//Add the entry to our array if it in in our desired directory
$files[] = $entry;
}
}
//Feed $files array to extractTo() to get only the files we want
if ($zip->extractTo($path, $files) === TRUE) {
return TRUE;
} else {
return FALSE;
}
$zip->close();
} else {
return FALSE;
}
} else {
return FALSE;
}
}
//Run the function
if (extractDir($zipfile, $path)) {
$extracted = "YES! :-D";
} else {
$extracted = "NO! :*(";
}
echo $extracted;
?>

Please be aware of the fact that using this function has OVERWRITE true.
an old file will be overwritten if the achieve (zipped file) contains file matching the same old file name.
old files that has no match in the zip, will be kept as is.
hopefully the someone will explain how to avoid overwriting old files.

I found it useful to add this to a function.
<?php
/**
* Extracts a ZIP archive to the specified extract path
*
* @param string $file The ZIP archive to extract (including the path)
* @param string $extractPath The path to extract the ZIP archive to
*
* @return boolean TURE if the ZIP archive is successfully extracted, FALSE if there was an errror
*
*/
function zip_extract($file, $extractPath) {
$zip = new ZipArchive;
$res = $zip->open($file);
if ($res === TRUE) {
$zip->extractTo($extractPath);
$zip->close();
return TRUE;
} else {
return FALSE;
}
} // end function
?>

Make attention when using this function with apache & windows system. Windows file system use \ (backslash) instead of unix / (slash)
Use str_replace like this.
<?php
$zip = new ZipArchive;
if ($zip->open("file.zip")){
$path = getcwd() . "/dirToextract/";
$path = str_replace("\\","/",$path);
echo $path;
echo $zip->extractTo($path);
$zip->close();
echo 'Done.';
} else {
echo "Error";
}
?>

This function, at least from my experience, maintains/forces the directory structure within the ZIP file.
ie. if you have FOLDER1/File1.txt in the zip file and you use
$zip->extractTo('/extract', 'FOLDER1/File1.txt');
the location of the extracted file will be:
/extract/FOLDER1/File1.txt
