PHP ʖ²ἯTH º󍋼/A V. Bzip2 Compression Functions ½鉜 The bzip2 functions are used to transparently read and write bzip2 (.bz2) compressed files. Шdz This module uses the functions of the bzip2 library by Julian Seward. This module requires bzip2/libbzip2 version = 1.0.x. °²װ Bzip2 support in PHP is not enabled by default. You will need to use the --with-bz2[=DIR] configuration option when compiling PHP to enable bzip2 support. ԋАʱŤփ ¸À©չģ¿鎴¶¨ҥȎºΉ薃ָn¡£ ׊Դ Ѝ This extension defines one resource type: a file pointer identifying the bz2-file to work on. Ԥ¶¨ҥ³£ ¸À©չģ¿鎴¶¨ҥȎºγ£¡£ ·¶= This example opens a temporary file and writes a test string to it, then prints out the contents of the file. =ד 1. Small bzip2 Example ?php $filename = "/tmp/testfile.bz2"; $str = "This is a test string.\n"; // open file for writing $bz = bzopen($filename, "w"); // write string to file bzwrite($bz, $str); // close file bzclose($bz); // open file for reading $bz = bzopen($filename, "r"); // read 10 characters print bzread($bz, 10); // output until end of the file (or the next 1024 char) and close it. print bzread($bz); bzclose($bz);? Ŀ¼ bzclose -- Close a bzip2 file pointer bzcompress -- Compress a string into bzip2 encoded data bzdecompress -- Decompresses bzip2 encoded data bzerrno -- Returns a bzip2 error number bzerror -- Returns the bzip2 error number and error string in an array bzerrstr -- Returns a bzip2 error string bzflush -- Force a write of all buffered data bzopen -- Open a bzip2 compressed file bzread -- Binary safe bzip2 file read bzwrite -- Binary safe bzip2 file write º󍋼/A ưµ㼯A bcsub ɏһ¼¶ bzclose
