Remove All Lines Less Than 3 Words Longs

[young_coder]

Dear all,
I want to remove all lines less than 3 words longs so I can stuff the rest into a db.
Can somebody help me?
Thank you in advance

an example of the text would help, my first thought would be to explode on line breaks to the the lines then explode on spaces to get the words then put it back together excluding the long lines.

there is alot of ways to accomplish this but you will have to parse everything line by line ether into tokens or the string itself.

Tokens are loads easier and most parsing is done with tokens.

but basicly you will have to read all your lines line by line and have conditions on what types of strings you are looking for. if the string matches your condition delete it or save it.

Depending on your definition of "word", this may or may not do what you wish.

$p = '#^(\W?\w+){2}\W?\n#m';
$o = preg_replace($p, '', $s);
