I am looping a row which has long characters (long sentence). As you can see I put a "-
" at the end of the chunk split for proper sentence breaks. I am just wondering why does it show a "-" at the last end of the string?

 <td valign="top">'.chunk_split($row['interventions'],20,"-<br>").'</td>

enter image description here

  • @lemonsss i need the dash for sentence breaking, i cant find a way to not loop that at the end – Ariel Apr 21 '18 at 04:57
  • So why do you need to loop? You need to post more code for us to see what is going on. – Andreas Apr 21 '18 at 05:00
  • @Andreas oops, wrong term sorry, the chunk split function still prints out the dash at the end of the string even if it doesnt exceed the limit – Ariel Apr 21 '18 at 05:02
  • @Ariel I see this as an [XY Problem](https://meta.stackexchange.com/q/66377/352329). This is a developer-applied separation of content, but the decision should be left to client-side. Let the table cell decide how to present overflowing text. I wouldn't add hyphens because it might confuse readers about whether there is actually a hyphen in the original text. Imagine if someone copy-pastes your content, they are going to collect more characters than actually exist. What if the user changes their browser font size / zoom-in/out?

Try to use preg_replace() to replace string at end with chunk_split

<td valign="top">'.preg_replace('/-<br>$/', '',chunk_split($row['interventions'],20,"-<br>")).'</td>

You can use str_split to make an array of the string, then join it back with implode.
Implode will not end the string with the delimiter.

$arr = str_split("abcdefghijklmn",5);
Echo implode("-<br>", $arr);

$arr = str_split($row['interventions'],20);

Echo '<td valign="top">'. implode("-<br>", $arr) .'</td>';

  • many thanks bro :), i just saw the solution the same time you posted the answer lol https://stackoverflow.com/questions/25433351/how-to-make-so-chunk-split-doesnt-add-something-at-the-end-of-the-string anyways thank you :) – Ariel Apr 21 '18 at 05:06
  • For obvious reasons, this answer is provably incorrect. The last character is not a hyphen, so rtrimming with a hyphen is useless. https://3v4l.org/ZNCEF – mickmackusa Jul 30 '22 at 12:41

This solved by

<td valign="top">'.substr(chunk_split($row['interventions'],20,"-<br>"), 0, -5).'</td>

Here -5 if length if 

"-<br>"

Get help from http://php.net/manual/en/function.chunk-split.php#39321

There is a - character in:

<td valign="top">'.chunk_split($row['interventions'],20,"-<br>").'</td>

Fix it by using:

<td valign="top">'.chunk_split($row['interventions'],20,"<br>").'</td>

    removing the dash will remove all dashes from the loop – Ariel Apr 21 '18 at 05:00
  • Ah i see. Okay, if your concern is about the word-wrapping hyphens, then i recommend you solve that via CSS or JS instead. Doing that in php will just make it difficult for yourself later on since ure lumping the formatting and logic together.
