Example #1 SplFileObject::getFlags() example
<?php
$file = new SplFileObject(__FILE__, "r");
if ($file->getFlags() & SplFileObject::SKIP_EMPTY) {
echo "Skipping empty lines\n";
} else {
echo "Not skipping empty lines\n";
}
$file->setFlags(SplFileObject::SKIP_EMPTY);
if ($file->getFlags() & SplFileObject::SKIP_EMPTY) {
echo "Skipping empty lines\n";
} else {
echo "Not skipping empty lines\n";
}
?>
以上例程的输出类似于：
