伪原创工具是一种基于SEO理论的网络文章编辑软件的统称，主要功能是把从网上复制来的文章进行“原创”操作。
让复制来的文章瞬间变的看起来像原创一样，然后达到让搜索引擎认为是“原创”从而提高网站收录率，和收录数量。
专门针对谷歌、百度、雅虎等大型搜索引擎收录设计，通过伪原创工具生成的文章，会更好的被搜索引擎收录和索引到。
方法一： 在线工具
这个就不多说了，直接谷歌一下就可以，实在不行就 点击这里，我帮你搜！
方法二： PHP 类
说白了，方法很简单，就是单词替换而已，只是词库才是重点，没有词库，一切都是浮云啊！
PHP Spintax Class
[^\{\}]+)|(?R))*)\}/x',
array($this, 'replace'),
$text
);
}
public function replace($text)
{
$text = $this->process($text[1]);
$parts = explode('|', $text);
return $parts[array_rand($parts)];
}
}
?>PHP Spintax Example Usage
process($string);
?>{Hello|Howdy|Hola} to you,
{Mr.|Mrs.|Ms.}
{Smith|Williams|Davis}!
Spintax Output: Howdy to you, Mrs.Davis!
当然，对于上面的方式，个人赶紧有点费时，下面有一个提供词库的类：
index.php
synonyms = require(dirname(__FILE__).'/dict-en.php');
}
//replace
function replace($text)
{
foreach($this->synonyms as $key => $val) {
if(preg_match("/".$key."/", $text) && !in_array($key, $this->replaced)) {
$text = str_replace($key, (is_array($val)?$val[array_rand($val)]:$val), $text);
array_push($this->replaced, $val);
}
}
return $text;
}
}
$spinner = new Ikeepstudying();
$text = '
WordPress has a mechanism for saving, updating, and retrieving individual, named pieces of data (options) in the WordPress database.
';
echo 'Dict
'; print_r($spinner->synonyms); echo '
';
echo 'Orginal
WordPress has a mechanism for saving, updating, and retrieving individual, named pieces of data (options) in the WordPress database.';
echo 'New Content (after every refresh, it may be differnt words)
'.$spinner->replace($text);
dict-en.php
array("mechanistic","medal","medallion","meddle","meddler","meddling","media"),
'saving' => array("saving clause",'savings and loan association','savoir-faire','savorless'),
'individual' => array("individualism", "individualist", "individualistic",'individuality','individualize','individually','indivisible'),
);
替换中文的道理是一样的！ 效果看这里：http://sources.ikeepstudying.com/spinner/
总结： 有词库才是硬道理！
