PHP article similarity comparison, through Similar_text () comparison is a bit slow, can there be any good efficiency?

PHP article similarity comparison, through Similar_text () comparison is a bit slow, can there be any good efficiency?
If the content of the article is to be compared by storing it all in text,
Is this method feasible through Similar_text () comparisons?

File difference commands that can be supplied with the operating system
Linux:diff
Window:fc
They're all done by line, and the more rows you report, the lower the natural similarity.

They are all processed by line, the more the number of rows reported, the lower the natural similarity is how to achieve it?

For example (window)

System ("FC 1.txt 2.txt > 3.txt"); ReadFile (' 3.txt ');

Linux also has the WC command to get the number of lines in the file

You can also use Exec to return an array of differential results directly

EXEC ("FC 1.txt 2.txt", $a);p rint_r ($a);

If you have the ability, you can also download and compile the Xdiff extension

What should I do if I read the database table information directly, traverse the content, and compare it to the article content that needs to be compared?
If I first participle, in the comparison by similarity, write algorithm What, is it possible?
Because once the database article data volume, by the database content to deposit text, then compare, will not be too slow?
