readgzfile()

(PHP 4, PHP 5, PHP 7)

Output a gz-file

说明

readgzfile(string $filename[,int $use_include_path= 0]): int

Reads a file, decompresses it and writes it to standard output.

readgzfile() can be used to read a file which is not in gzip format; in this case readgzfile() will directly read from the file without decompression.

参数

$filename

The file name. This file will be opened from the filesystem and its contents written to standard output.

$use_include_path

You can set this optional parameter to1, if you want to search for the file in the include_path too.

返回值

Returns the number of(uncompressed)bytes read from the file on success,或者在失败时返回FALSE

错误／异常

失败时抛出E_WARNING警告。

This is a rather simple example of usage for this function, but it does work, and it solved a problem I was using with old browsers accessing gzipped files. 
 
There is no need for any html formating if the source file is an HTML formated page, such as the ones I'm using are. Checking the browser version, sends either the gzip file directly, or sends the browser to a page like this, which does the work for it. Well done simple function. 
My server is running PHP 4.2.2 on Linux Redhat version 9 and
Apache 2.0.40
