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>

Try to add rtrim() at end with chunk_split

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

https://3v4l.org/DMj9E

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

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

This solved by

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

Here -5 if length if 

"-<br>"

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.
