gzgets — Get line from file pointer

说明

gzgets(resource $stream, ?int $length = null): string|false

Gets a (uncompressed) string of up to length - 1 bytes read from the given file pointer. Reading ends when length - 1 bytes have been read, on a newline, or on EOF (whichever comes first).

参数

stream: The gz-file pointer. It must be valid, and must point to a file successfully opened by gzopen().
length: The length of data to get.

返回值

The uncompressed string, or false on error.

<?
// this is simple code by VIJAY to unzip .gz file
$file = "/absolute/path/to/your/file" ;
$fp = fopen("$file", "w") ;
// file to be unzipped on your server
$filename = "filename.gz" ;
$zp = gzopen($filename, "r");

if ($zp)
{
  while (!gzeof($zp))
  {
    $buff1 = gzgets ($zp, 4096) ;
    fputs($fp, $buff1) ;
  }                
}            
gzclose($zp) ;
fclose($fp) ;
?>

PS when it encounters and breaks on a newline byte ("\n"), the newline byte itself is not included in the returned string.

For the above example by VIJAY, using gzgetc would be better, as I've encountered binary/text file incompatibilities (at least with PHP 4.0.4).
