How can I extract or uncompress gzip file using php?
提问by Farzam Tahmasebmirza
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);
}
I tried this code but this does not work, I get:
我试过这段代码，但这不起作用，我得到：

试试这个在这里找到
//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);
