Description: ------------ Using version 1.0, I get a divide by zero error when passing a string that has no end-of-sentence punctuation. Also, an empty string elicits an extra divide by zero error. A couple of approaches could be used to fix this. First, suppress the errors using the @ operator. Second, explicitly detect possible divide by zero conditions and either return some null value or force it to divide by one. Any solution would be viable. However, given the way the class works, either supressing the error or dividing by one is probably best. Reproduce code: --------------- $x = new Text_Statistics(''); $y = new Text_Statistics('Four score and seven years ago'); echo $x->flesch . "\n"; echo $y->flesch . "\n"; Expected result: ---------------- 205.82 87.945 -or- 206.835 94.035 (either one is acceptable, since it's not a complete sentence) Actual result: -------------- Warning: Division by zero in /usr/share/php/Text/Statistics.orig.php on line 138 Warning: Division by zero in /usr/share/php/Text/Statistics.orig.php on line 139 Warning: Division by zero in /usr/share/php/Text/Statistics.orig.php on line 138 206.835 94.035

This bug has been fixed in CVS. If this was a documentation problem, the fix will appear on by the end of next Sunday (CET). If this was a problem with the website, the change should be live shortly. Otherwise, the fix will appear in the package's next release. Thank you for the report and for helping us make PEAR better.
