- $word2compare = "stupid";
-
- $words = array(
- 'stupid',
- 'stu and pid',
- 'hello',
- 'foobar',
- 'stpid',
- 'upid',
- 'stuuupid',
- 'sstuuupiiid',
- );
-
- while(list($id, $str) = each($words)){
- similar_text($str, $word2compare, $percent);
- print "Comparing '$word2compare' with '$str': ";
- print round($percent) . "%\n";
- }
-
- /*
