| 5 | // 15/07/2006 (2.6) |
||
| 6 | // - Changed the algorithm to parse the ZIP file.. Now, the script will try to mount the compressed |
||
| 7 | // list, searching on the 'Central Dir' records. If it fails, the script will try to search by |
||
| 8 | // checking every signature. Thanks to Jayson Cruz for pointing it. |
||
| 9 | // 25/01/2006 (2.51) |
||
| 10 | // - Fixed bug when calling 'unzip' without calling 'getList' first. Thanks to Bala Murthu for pointing it. |
||
| 11 | // 01/12/2006 (2.5) |
||
| 12 | // - Added optional parameter "applyChmod" for the "unzip()" method. It auto applies the given chmod for |
||
| 13 | // extracted files. |
||
| 14 | // - Permission 777 (all read-write-exec) is default. If you want to change it, you'll need to make it |
||
| 15 | // explicit. (If you want the OS to determine, set "false" as "applyChmod" parameter) |
||
| 16 | // 28/11/2005 (2.4) |
||
| 17 | // - dUnzip2 is now compliant with old-style "Data Description", made by some compressors, |
||
| 18 | // like the classes ZipLib and ZipLib2 by 'Hasin Hayder'. Thanks to Ricardo Parreno for pointing it. |
||
| 19 | // 09/11/2005 (2.3) |
||
| 20 | // - Added optional parameter '$stopOnFile' on method 'getList()'. |
||
| 21 | // If given, file listing will stop when find given filename. (Useful to open and unzip an exact file) |
||
| 22 | // 06/11/2005 (2.21) |
||
| 23 | // - Added support to PK00 file format (Packed to Removable Disk) (thanks to Lito [PHPfileNavigator]) |
||
| 24 | // - Method 'getExtraInfo': If requested file doesn't exist, return FALSE instead of Array() |
||
| 25 | // 31/10/2005 (2.2) |
||
| 26 | // - Removed redundant 'file_name' on centralDirs declaration (thanks to Lito [PHPfileNavigator]) |
||
| 27 | // - Fixed redeclaration of file_put_contents when in PHP4 (not returning true) |

||
| 35 | # |
||
| 36 | # Objective: |
||
| 37 | # This class allows programmer to easily unzip files on the fly. |
||
| 38 | # |
||
| 39 | # Requirements: |
||
| 40 | # This class requires extension ZLib Enabled. It is default |
||
| 41 | # for most site hosts around the world, and for the PHP Win32 dist. |
||
| 42 | # |
||
| 43 | # To do: |
||
| 44 | # * Error handling |
||
| 45 | # * Write a PHP-Side gzinflate, to completely avoid any external extensions |
||
| 46 | # * Write other decompress algorithms |
||
| 47 | # |
||
| 48 | # If you modify this class, or have any ideas to improve it, please contact me! |
||
| 49 | # You are allowed to redistribute this class, if you keep my name and contact e-mail on it. |
||
| 50 | # |
||
| 51 | # PLEASE! IF YOU USE THIS CLASS IN ANY OF YOUR PROJECTS, PLEASE LET ME KNOW! |
||
| 52 | # If you have problems using it, don't think twice before contacting me! |
