    readgzfile — Output a gz-file

    Опис

    readgzfile(string $filename, int $use_include_path = 0): int|false

    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.

    Параметри

    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.

    Значення, що повертаються

    Returns the number of (uncompressed) bytes read from the file on success, або false в разі помилки

    Помилки/виключення

    Під час збоїв буде видаватись E_WARNING.

    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.

    <?PHP

    // first we need to stop the server from sending any headers at all.
    ob_start();

    readgzfile("test.html.gz"); // read the file and output directly to
    the browser
    // non compressed data from the
    file

    ob_end_flush    (); // let the headers go//

    ?>

    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
