readgzfile — Output a gz-file
说明
int readgzfile ( string $filename [, int $use_include_path = 0 ] )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 to 1, 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. If an error occurs, FALSE is returned and unless the function was called as @readgzfile, an error message is printed.
