php - select 1 random keyword per line in txtGet the solution ↓↓↓
To select a random keyword from that file:
<?php //$keywords = file('keyword.txt'); OR $keywords = explode("\n", file_get_contents('keyword.txt')); echo $keywords[ array_rand($keywords) ]; ?>
I'm not sure I understand the question correctly, but if you want to replace your current keyword selection with a random keyword per line, you need to change:
with something like:
$kwds = explode(" ", $kw[$i]); // although I would use foreach to loop through the lines array... $kwd = reset(shuffle($kwds)); // shuffle the keywords in that line and pick the first one
