It might be a simple task. But I am new to PHP.
I am creating a string of values getting from database for a specific purpose.
How to remove last char from string.
$str=''; foreach($dataarray as $value) { $str.=$value."##"; } it gives me string like ABC##DEF##GHI##
I have to remove last 2 chars ##
EDIT:
have shown here sample code . actull y array is 2D. so cant use implode()
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); 
'##' and then removing them again is probably still too funky :)
<?php $str = "1,2,3,4,5,"; echo chop($str,","); ?> It will remove last comma (,) from the string $str
You can use Implode() for making such string instead of making it manually
implode("##",$dataarray); BTW for removing last char you can do like below:
substr($str,0,(strlen($str)-2)); 
There's a few ways to go about it but:
$str = rtrim($str, "#"); 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.
Maybe
$str=''; $first = true; foreach($dataarray as $value) { if(!$first) { $str .= "##"; } else { $first = false; } $str .= $value; }
