PHP has its own inbuilt class that can be used to unzip or extracts contents from a zip file  The class is ZipArchive  Below is the simple and basic PHP code that will extract a zip file and place it in a specific directory    lt  php  zip obj   new ZipArchive   zip obj- gt open  dummy zip     zip obj- gt extractTo  directory name sub dir      gt    If you want some advance features then below is the improved code that will check if the zip file exists or not    lt  php  zip obj   new ZipArchive  if   zip obj- gt open  dummy zip       TRUE        zip obj- gt extractTo  directory sub dir       echo  Zip exists and successfully extracted     else      echo  This zip file does not exists       gt    Source  How to unzip or extract zip files in PHP

Please  don t do it like that  passing GET var to be a part of a system call   Use ZipArchive instead   So  your code should look like    zipArchive   new ZipArchive     result    zipArchive- gt open   GET  master     if   result     TRUE         zipArchive - gt extractTo  my dir         zipArchive - gt close           Do something else on success   else          Do something on error     And to answer your question  your error is  something  var something else  should be  something  var something else   in double quotes

I can only assume your code came from a tutorial somewhere online  In that case  good job trying to figure it out by yourself  On the other hand  the fact that this code could actually be published online somewhere as the correct way to unzip a file is a bit frightening   PHP has built-in extensions for dealing with compressed files  There should be no need to use system calls for this  ZipArchivedocs is one option    zip   new ZipArchive   res    zip- gt open  file zip    if   res     TRUE       zip- gt extractTo   myzips extract path        zip- gt close      echo  woot      else     echo  doh        Also  as others have commented   HTTP GET VARS has been deprecated since version 4 1     which was a reeeeeally long time ago  Don t use it  Use the   GET superglobal instead   Finally  be very careful about accepting whatever input is passed to a script via a   GET variable   ALWAYS SANITIZE USER INPUT     UPDATE  As per your comment  the best way to extract the zip file into the same directory in which it resides is to determine the hard path to the file and extract it specifically to that location  So  you could do      assuming file zip is in the same directory as the executing script   file    file zip       get the absolute path to  file  path   pathinfo realpath  file   PATHINFO DIRNAME     zip   new ZipArchive   res    zip- gt open  file   if   res     TRUE         extract it to the path we determined above    zip- gt extractTo  path      zip- gt close      echo  WOOT   file extracted to  path     else     echo  Doh  I couldn t open  file
