参见英文答案 > How can I unzip a .gz file with PHP?                                    5个

function uncompress($srcName, $dstName) {
    $sfp = gzopen($srcName, "rb");
    $fp = fopen($dstName, "w");

    while ($string = gzread($sfp, 4096)) {
        fwrite($fp, $string, strlen($string));
    }
    gzclose($sfp);
    fclose($fp);
}

我试过这段代码,但这不起作用,我得到：

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request. Please contact the server administrator, webmaster@domain.com and inform them of the time the error occurred, and anything you might have done that may have caused the error. More information about this error may be available in the server error log.
Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

解决方法:

试试这个发现here

//This input should be from somewhere else, hard-coded in this example
$file_name = '2013-07-16.dump.gz';

// Raising this value may increase performance
$buffer_size = 4096; // read 4kb at a time
$out_file_name = str_replace('.gz', '', $file_name); 

// Open our files (in binary mode)
$file = gzopen($file_name, 'rb');
$out_file = fopen($out_file_name, 'wb'); 

// Keep repeating until the end of the input file
while (!gzeof($file)) {
    // Read buffer-size bytes
    // Both fwrite and gzread and binary-safe
    fwrite($out_file, gzread($file, $buffer_size));
}

// Files are done, close files
fclose($out_file);
gzclose($file);
