Description:
------------
The manual said that "w" mode for fopen() will place the file pointer
at the beginning of the file and truncate the file to zero length. But
the file cannot be truncated using that "w" mode by fopen().
Reproduce code:
---------------
<?
$file = "t.log";
$add_content = "add this";
/* prepare the file to be truncated */
$fh = fopen($file, 'w');
$res = fwrite($fh, $add_content) or die("write file error");
fclose($fh);
echo $file . " size : " . filesize($file) . "bytes. \n";
$sh = fopen($file, 'w');
fclose($sh);
echo $file . " size : " . filesize($file) . "bytes. \n";
?>
Expected result:
----------------
t.log size : 8bytes.
t.log size : 0bytes.
Actual result:
--------------
t.log size : 8bytes.
t.log size : 8bytes.
