Question

[PHP] - Split html text without breaking "open" tags

Answer 1

+1 A:

The "correct" way would be to parse the HTML and perform the shortening operations on its text nodes. In PHP5 you could use the DOM extension, and specifically DOMDocument::loadHTML().

You have to be sure that the tags are coded correctly using this tool? What if tags are spoiled?

"Unlike loading XML, HTML does not have to be well-formed to load." -- the results may be unexpected but it should be able to at least parse it. Also from the `loadHTML` manual page: "DOMDocument is very good at dealing with imperfect markup, but it throws warnings all over the place when it does."

@Riccardo DOM can load HTML even if it is invalid. You wont be able to use getElementById but everything else should work. If DOM throws warnings about the markup, you can enable custom error handling and clear the errors. See http://kore-nordmann.de/blog/0081_parse_html_extract_data_from_html.html

Answer 2

A:

Hmmm I've used a code where I had to split the copy entered by a WYSIWYG and wanted to retrieve the first paragraph from it. Its little dodgy but did the trick for me. If you wanted to add in show "n" then you could add that to the "intro" var using substr. Hope this starts you off :-|

function break_html_description_to_chunks($description = null)
{
    $firstParaEnd = strpos($description,"</p>");
    $firstParaEnd += 4;
    $intro = substr($description, 0, $firstParaEnd);

    $body = substr($description, $firstParaEnd, strlen($description));
    $temp = array("intro" => $intro, "body" => $body);
    return $temp;
}
