I tried your zipfile aswell. Can you try a snapshop from http://snaps.php.net and see if you still have this crash? -- robin ------------------------------------------------------------------------ [2002-02-21 00:58:44] leigh@cfgn.net The zip functions in PHP4.1.1 appears to be causing PHP to crash with a segmentation fault. When using it in my project I get a "document contains no data". I borrowed the script used in a previous bug report. <?php $zip = zip_open("test_zip.zip"); if ($zip) { echo "Ok, entering while..\n"; while ($zip_entry = zip_read($zip)) { echo "In while..\n"; echo "Name: " . zip_entry_name($zip_entry) . "\n"; echo "Actual Filesize: " . zip_entry_filesize($zip_entry) . "\n"; echo "Compressed Size: " . zip_entry_compressedsize($zip_entry) . "\n"; echo "Compression Method: " . zip_entry_compressionmethod($zip_entry) . "\n"; if (zip_entry_open($zip, $zip_entry, "r")) { echo "File Contents:\n"; $buf = zip_entry_read($zip_entry, zip_entry_filesize($zip_entry)); echo "$buf\n"; zip_entry_close($zip_entry); } echo "\n"; } zip_close($zip); } ?> [leigh@eden debug]$ php-debug ./test.php X-Powered-By: PHP/4.1.1 Content-type: text/html Ok, entering while..
