(PHP 4 = 4.1.0) Reads up to length bytes from an open directory entry. If length is not specified, then zip_entry_read() will attempt to read 1024 bytes. The parameter zip_entry is a valid directory entry returned by zip_read(). 注意 The length parameter should be the uncompressed length you wish to read. Returns the data read, or false if the end of the file is reached. See also zip_entry_open(), zip_entry_close() and zip_entry_filesize().
