Test code < /textarea> <br> <input type="submit" name="Submit" value="Submit" /> <br></form> <br><? <BR>$c <BR>//echo $content; <BR>$ft=array ("<br />","</p>"); <br>//echo count($ft); <br>$html = "abaaaaaaa<br />csssssssssssssssssd<br />efdddddddddddddddd"; <br> preg_match_all ("|(<br />)|U",$html,$out, PREG_PATTERN_ORDER); <br> while (list($key,$value) = each($out[1])) { <br> } <br> $keywords = preg_split ("/(<br />)/", $html); <br>//echo $html; <br>$pagesize=10; <br>$size=0; <br>$h=""; <br>for ($i=0; $i< count($keywords); $i++) { <BR> if($size<$pagesize){ <BR> $size+=strlen($keywords[$i]); <BR>// echo "size= ".$size; <BR> $h.=$keywords[$i]; <BR> } <BR>} <br>echo $h; <BR>?> <br>The idea is to use <br /> to decompose the article content into multiple blocks to form The array <br> then iterates through the example, and at the same time combines the article content blocks bit by bit until its length is greater than $pagesize <br> This is a good method. Use regular preg_split to divide the article content, taking into account that in the future, not only use < br /> Use </p> or more delimiters at the same time<br>But the problem is that after using multiple delimiters at the same time, it is impossible to determine which delimiter a certain paragraph is divided according to. The article content cannot be completely restored<br> The project is relatively tight, and the editor for adding articles is fckeditor. Each article has n number of </br>. I will not consider multiple separators for the time being. So it is not a complete solution. <br> <br> The above introduces the incomplete solution of automatic paging in Solution Explorer, including the content of Solution Explorer. I hope it will be helpful to friends who are interested in PHP tutorials. </p> <p> </p> <p></p>
