remove last comma

Question

I want to remove "," from the given string in $code variable but the result is showing "Array" in $code1 instead of balakrishnan. How to rectify the error.

$code="balakrishnan,";
$code1 = explode(',', $code);

Answer 1

You don't want explode() which splits a string up into an array. You want str_replace() which replaces all occurrences of the search string with the replacement string:

$code1 = str_replace(',', '', $code);

or, in your use case, rtrim() would work, too:

$code1 = rtrim($code, ',');

edit

You do want to use explode(), you just need to access the variables correctly.

$code1 = explode(',',"balakrishnan,kumar,vinoth");
echo $code1[0]; // prints "balakrishnan"

Answer 2

If, for some reason you still want to use explode, just do:

echo $code1[0];

Answer 3

There is a dozen ways to do this. If you use explode(), also use implode() again.

$code="balakrishnan,";
$code1 = implode('',explode(',', $code));

$code="balakrishnan,";
$code1 = str_replace(',','', $code);

$code="balakrishnan,";
$code1 = substr($code,0,-1);

etc...

I would say, go with my last solution, because in the future you might have other commas in the middle of your string which you might want to keep.
