note 27418 added to function.strtok

Here's some code to extract the first part of a long paragraph, e.g. to use as a summary. Starting at the beginning of the paragraph it gets as many complete sentences as are necessary to contain $limit words. For example, with $limit at 20 it would return the first two sentences of the paragraph you're reading right now (the first 20 words plus the rest of the sentence in which the limit was hit). function summarize($paragraph, $limit){ $tok = strtok($paragraph, " "); while($tok){ $text .= " $tok"; $words++; if(($words >= $limit) && ((substr($tok, -1) == "!")||(substr($tok, -1) == "."))) break; $tok = strtok(" "); } return ltrim($text); } Might be a better way to do this, but it worked for me. Hope you find it useful! -- http://www.php.net/manual/en/function.strtok.php http://master.php.net/manage/user-notes.php?action=edit+27418 http://master.php.net/manage/user-notes.php?action=delete+27418 http://master.php.net/manage/user-notes.php?action=reject+27418
