how to prevent extracting a php file from zip - php

Question

i am using this piece of code to unzip a .zip file
$zip = new ZipArchive;
if ($zip->open('test.zip') === TRUE) {
$zip->extractTo('/my/destination/dir/');
$zip->close();
echo 'ok';
} else {
echo 'failed';
}
Lets say: there is a .php file in the .zip and i do not want a .php file to be extracted. How can i prevent that?

Answer 1

You can try something like this for PHP >= 5.5:
$zip = new ZipArchive;
if ($zip->open('test.zip') === TRUE) {
for ($i = 0; $i < $zip->numFiles; $i++) {
if( pathinfo($zip->getNameIndex($i)['extension'] != "php")){
$zip->extractTo('/my/destination/dir/', $zip->getNameIndex($i));
}
}
$zip->close();
}
Or this for PHP < 5.5:
$zip = new ZipArchive;
if ($zip->open('test.zip') === TRUE) {
for ($i = 0; $i < $zip->numFiles; $i++) {
$path_info = pathinfo($zip->getNameIndex($i));
$ext = $path_info['extension'];
if( $ext != "php")){
$zip->extractTo('/my/destination/dir/', $zip->getNameIndex($i));
}
}
$zip->close();
}
The only difference between the two is the pathinfo function. Both will loop all files inside the zip file and, if the file extension isn't php, extracts it to /my/destination/dir/.

$zip= new ZipArchive;
if($zip->open('test.zip') === TRUE){
for($i = 0; $i < $zip->numFiles; $i++) {
$filename = pathinfo($zip->getNameIndex($i));
$fileinfo = $filename['extension'];
if($fileinfo!="php"){
$zip->extractTo('extract/',$zip->getNameIndex($i));
}
$zip->close();
}
