Jon Stirling have right in his comment. If you try to create json manually - it's bad idea.

But anwser to your question should be something like this (didn't test it) :

<?php
$tab=explode(",",$string);
array_pop($tab);
$string=implode(",",$tab).']';
?>

Just use php rtrim() function on the string you will get your result.

like below

<?php 

$text = '{"location":"Park Town,Chennai,Tamil Nadu" },{"location":"Arajar Salai,Simmakkal,Madurai" },';


$test = rtrim($text,',');
echo $test;
?>

  • location is not static , location is generating dynamically right now two record is appearing after some time 3 or 4 records will appear – techiva.blogspot.com Aug 23 '17 at 10:40
  • OK. That's not a problem. We can trim the last comma after formation of your string that is outside of your loop. – Saroj Aug 23 '17 at 10:43
