bool is_writable (string $filename)
DESCRIPTION

taken into account.
PARAMETERS
o $filename
- The filename being checked.
RETURN VALUES
Returns TRUE if the $filename exists and is writable.
EXAMPLES
Example #1
is_writable(3) example
<?php
$filename = 'test.txt';
if (is_writable($filename)) {
echo 'The file is writable';
} else {
echo 'The file is not writable';
}
?>
ERRORS /EXCEPTIONS

The results of this function are cached. See clearstatcache(3) for more details.
