How to remove last char from s

Answer 1

If the implode method isn't appropriate, then after your foreach loop, you can try one of these functions:

http://www.php.net/manual/en/function.rtrim.php

$str = rtrim($str,'#');

http://php.net/manual/en/function.substr.php

$str = substr($str,-2);

If you have a 2D array, you could still use the implode func like this:

$a = array();
foreach( $foo as $bar )
  foreach( $bar as $part )
    $a[] = $part;
$str = implode('##',$a);

Answer 2

You can use Implode() for making such string instead of making it manually

implode("##",$dataarray);

BTW for removing last char you can do like below:

substr($str,0,(strlen($str)-2));

Answer 3

You could use PHP's function implode

$str = implode("##", $dataarray);

Answer 4

There's a few ways to go about it but:

$str = rtrim($str, "#");

Answer 5

http://php.net/manual/en/function.substr-replace.php

$newstr = substr_replace($longstr ,"",-2);

This will create $newstr by taking $longstr and removing the last tow characters.

Answer 6

Maybe

$str='';
$first = true;
foreach($dataarray as $value) {
     if(!$first) {
          $str .= "##";
     }
     else {
          $first = false;
     }
     $str .= $value;
