PHP自动获取关键字问题
标题<input type="text" name="title" id="title" />
内容：<input type="text" name="content" id="content" />
关键字：<input type="text" name="keywords" id="keywords" />
当keywords为空时，自动获取关键字。
各位大神，什么写？
新手求虐、、、
PHP 关键字 自动关键字
[解决办法]
比如
require 'pscws4.class.php';
$text = '这里是标题测试文档';
$cws = new PSCWS4('gbk');
$cws->set_dict('etc/dict.xdb');
$cws->set_rule('etc/rules.ini');
$cws->send_text($text);
echo "<xmp>Top words stats:\n\n";
$ret = array();
$ret = $cws->get_tops(10,'r,v,p');
echo "No.\tWord\t\tAttr\tTimes\tRank\n------------------------------------------------------\n";
$i = 1;
foreach ($ret as $tmp)
{
printf("%02d.\t%-16s\t%s\t%d\t%.2f\n", $i++, $tmp['word'], $tmp['attr'], $tmp['times'], $tmp['weight']);
}
$cws->close();
Top words stats:
No.WordAttrTimesRank
