limit text length in html and provide 'read more' link
limit text length css

I have text stored in the php variable $text. This text can be 100 or 1000 or 10000 words. As currently implemented, my page extends based on the text, but if the text is too long the page looks ugly.

I want to get the length of the text and limit the number of characters to maybe 500, and if the text exceeds this limit I want to provide a link saying, "Read more." If the "Read More" link is clicked, it will show a pop with all the text in $text.

This is what I use:

// strip tags to avoid breaking any html
$string = strip_tags($string);
if (strlen($string) > 500) {

    // truncate string
    $stringCut = substr($string, 0, 500);
    $endPoint = strrpos($stringCut, ' ');

    //if the string doesn't contain any space then it will cut without word basis.
    $string = $endPoint? substr($stringCut, 0, $endPoint) : substr($stringCut, 0);
    $string .= '... <a href="/this/story">Read More</a>';
}
echo $string;

You can tweak it further but it gets the job done in production.

  • can there be markup in $text?
  • Thanks for the Answer , but after using strip_tags($strings) , the html is lost , how can I after reducing the string length retain the html back which was previously present
  • @harshal The strip_tags is in there because most sites I've worked on just want plain text blurbs (that then link to the page with the fully formatted article). If you want to retain the HTML you can use an XML parser to grab the text values of each sub-element, accumulating the character count while also checking for possible tag breakage. That is a much more complex problem and well beyond the scope of this question.
  • @Webbiedave what is the href here?? sorry i did not understand it thats why i asked?? should it point to self page or something else?
  • "make sure it ends in a word so assassinate doesn't become ass... " ROFL
  • Three dots will be wont be added to a result if the first statement in a ternary check is true. So, brackets should be added around ternary check $teaser = ($endPoint ? substr($stringCut, 0, $endPoint) : substr($stringCut, 0)) . ' ...'; Beside that, it's nice solution.
  • you can change the "..." to a link to more information, or make it open a div with the whole block of text on the same page. Lots of options..
  • please format your answer next time. there are appropriate buttons at the top of the textarea
  • As this is a formatting issue, it's preferred to limit based on character count rather than word count as words will be of varying length.
  • @stillstanding: Thanks, I didn't realize it has removed the returns until after I had posted. I assumed it would be shown as typed.
  • You DO realize that is 500 LETTERS, not words, rite? :D Also, this can completely break the code of the side, if there is any HTML code (can result like <im instead of <img> ...)
  • Ok so use strip_tags() inside ;)
  • @Aif I edit my function withe the split_words function. Hope this help :)
