To generate a zip file in php, we only need to use a php zip compression ZipArchive function. The following small series will summarize the two implementations. One is to use ZipArchive to generate a zip file, all files in another compressed folder.
Note:
ZipArchive to compress files. This is an extension class of php. It has been supported since php5.2. If you encounter an error while using it, check php. in ini, have you removed the semicolon before extension = php_zip.dll, and then restart Apache to use this class library.
Example 1
Generate zip compressed files
| The Code is as follows: |
Copy code |
<? Php
/* Generate a zip compressed file */
Function create_zip ($ files = array (), $ destination = '', $ overwrite = false ){
// If the zip file already exists and overwrite is false, return false
If (file_exists ($ destination )&&! $ Overwrite) {return false ;}
// Vars
$ Valid_files = array ();
// If files were passed in...
If (is_array ($ files )){
// Cycle through each file
Foreach ($ files as $ file ){
// Make sure the file exists
If (file_exists ($ file )){
$ Valid_files [] = $ file;
}
}
}
// If we have good files...
If (count ($ valid_files )){
// Create the archive
$ Zip = new ZipArchive ();
If ($ zip-> open ($ destination, $ overwrite? ZIPARCHIVE: OVERWRITE: ZIPARCHIVE: CREATE )! = True ){
Return false;
}
// Add the files
Foreach ($ valid_files as $ file ){
$ File_info_arr = pathinfo ($ file );
$ Zip-> addFile ($ file, $ file_info_arr ['basename']); // remove the hierarchical directory
}
// Debug
// Echo The zip archive ins INS, $ zip-> numFiles, 'files with a status of ', $ zip-> status;
// Close the zip -- done!
$ Zip-> close ();
// Check to make sure the file exists
Return file_exists ($ destination );
}
Else
{
Return false;
}
}
Define ('rootpath', dirname (_ FILE _); // website path
$ Files_to_zip = array (
Rootpath.directory_separator.'php?jquery=cookbook ',
ROOTPATH.DIRECTORY_SEPARATOR.'TurboListerZeroTemplate.csv'
);
// If true, good; if false, zip creation failed
Using filename='my-archive.zip ';
$ Result = create_zip ($ files_to_zip, $ filename ); |
Example 2
Compress all files in the folder
| The Code is as follows: |
Copy code |
<? Php
/*
All files in the zip compressed php folder
*/
Class HZip
{
/**
* Add files and subdirectories to a zip file.
* @ Param string $ folder
* @ Param ZipArchive $ zipFile
* @ Param int $ exclusiveLength Number of text to be exclusived from the file path.
*/
Private static function folderToZip ($ folder, & $ zipFile, $ exclusiveLength ){
$ Handle = opendir ($ folder );
While (false! ==$ F = readdir ($ handle )){
If ($ f! = '.' & $ F! = '..'){
$ FilePath = "$ folder/$ f ";
// Remove prefix from file path before add to zip.
$ LocalPath = substr ($ filePath, $ exclusiveLength );
If (is_file ($ filePath )){
$ ZipFile-> addFile ($ filePath, $ localPath );
} Elseif (is_dir ($ filePath )){
// Add a subfolder
$ ZipFile-> addEmptyDir ($ localPath );
Self: folderToZip ($ filePath, $ zipFile, $ exclusiveLength );
}
}
}
Closedir ($ handle );
}
/**
* Zip a folder (include itself ).
* Usage:
* HZip: zipDir ('/path/to/sourcedir','/path/to/out.zip ');
*
* @ Param string $ sourcePath Path of directory to be zip.
* @ Param string $ outZipPath Path of output zip file.
*/
Public static function zipDir ($ sourcePath, $ outZipPath)
{
$ PathInfo = pathInfo ($ sourcePath );
$ ParentPath = $ pathInfo ['dirname'];
$ DirName = $ pathInfo ['basename'];
$ SourcePath = $ parentPath. '/'. $ dirName; // prevents the bug of passing the 'folder' folder
$ Z = new ZipArchive ();
$ Z-> open ($ outZipPath, ZIPARCHIVE: CREATE); // CREATE a zip file
$ Z-> addEmptyDir ($ dirName); // create a folder
Self: folderToZip ($ sourcePath, $ z, strlen ("$ parentPath /"));
$ Z-> close ();
}
}
// Usage
HZip: zipDir ('yourlife', 'yourlife.zip ');
?> |
/******** Optional ziparchive parameter *******/
/*
1. ZipArchive: addEmptyDir
Add a new file directory
2. ZipArchive: addFile
Add the file to the specified zip package.
3. ZipArchive: addFromString
Add the content to the added file at the same time.
4. ZipArchive: close
Disable ziparchive
5. ZipArchive: extrac.pdf
Decompress the package
6. ZipArchive: open
Open a zip package
7. ZipArchive: getStatusString
Returns the status content during compression, including error information and compression information.
8. ZipArchive: deleteIndex
Delete a file in the compressed package, for example, deleteIndex (0). Delete the first file.
9. ZipArchive: deleteName
Delete a file name in the package and delete the file.
