Note Submitter: chris at mad-teaparty dot com ---- This snippet shows how to write ZIP-Files using PHP's Java-API: --------------------------- // specify the name of the zip file to be created $zipfile = "/usr/local/apache/htdocs/skripte/test.zip"; // files that should be zipped $filenames = array("test.php", "index.html"); // create a zip output stream $out = new Java('java.util.zip.ZipOutputStream', new Java('java.io.FileOutputStream', $zipfile)); // walk through the array an add each file to the archive foreach ($filenames as $entry) { $content = implode("", file($entry)); // read the file $zipentry = new Java('java.util.zip.ZipEntry', $entry); //define a new zip entry $out->putNextEntry($zipentry); //write this entry to the archive $out->write($content, 0, strlen($content)); //add the content $out->closeEntry(); // close the current entry } $out->setComment("test..."); // set a comment for the zip file $out->close(); //close the output stream ---------------------------- This is just "proof of concept". It doesn't set all values for zip entries, like CRC32-checksum, compressed size etc. Several hints: - in order to read or write JAR-archives, the snippet needs only few modification: replace the ZIPOutputStream with an instance of "JarOutputStream" or "JarInputStream", defined in "java.util.jar" - use double backslashes for path names on Windows, eg. "C:\\apache\\htdocs\\index.html" - if you specify an absolute path name for a single zip entry, a directory will be created in the zip archive. Thus, you can "zip" whole directories by walking through them - If you want to set the time when the zip entry was added, note that the Java-method "setTime" requires a long value (millisec). I did this: $zipentry->setTime(time()*1000); - If you want to add the CRC-checksum to each zip entry, do not (!) use PHP's crc32-function! Incompatible types will cause loss of precision and wrong checksums. Use the Java-class "CRC32" instead: $crc32 = new Java('java.util.zip.CRC32'); $crc32->update($content); $zipentry->setCrc($crc32->getValue()); $crc32->reset();
