gzread

说明

string gzread ( resource zp, int length )

gzread() reads up to length bytes from the given gz-file pointer. Reading stops when length (uncompressed) bytes have been read or EOF is reached, whichever comes first.

参数

zp: The gz-file pointer. It must be valid, and must point to a file successfully opened by gzopen().
length: The number of bytes to read.

Be aware that gzread's second parameter - length reffers to the file's uncompressed size, therefore using this code:



<?php

$file_name = "/usr/local/something.txt.gz";

if($file_handle = gzopen($file_name, "r"))

{

    $contents = gzread($file_handle, filesize($file_name));

    gzclose($file_name);

}

?>



will probably truncate the content of the file as filesize checks for the file's compressed size.

So either use the actual uncompressed size, if you know it, or use an aribtrary big enough length, as gzreading will stop at the end of the file anyway.
