PHP problem

[chicken]

Why does this 'if' statement work:

$filesize = filesize($inputFile);
if ($filesize > 0) {
  //print "<br/>debug, $inputFile is $filesize\n";
  $result = xslt_process($xh, $inputFile, "searchResults.xsl");
  return $result;
}

When this 'if' statement does not:

if (filesize($inputFile) > 0) {
  //print "<br/>debug, $inputFile is $filesize\n";
  $result = xslt_process($xh, $inputFile, "searchResults.xsl");
  return $result;
}

ARGH! WTF? Am I thinking in Perl here or something?

I guess this could be a precedence issue? Maybe try
if ( (filesize($inputFile)) > 0 ). I'm not convinced this is right, though. I abhor PHP.
