I want to remove last comma only from the string... which is },]}
I want to remove the comma only..
I have tried this :
echo substr(trim($resultstr), 0, -4);
but it removes all the 4 characters from last.
You could use a regular expression. Something like /\\},(\\s+)\\]/m
should work.
$data = preg_replace('/\},(\s+)\]/m', '}$1]', $data);
But instead of fixing this part, you should fix the code, which generates the wrong ,
inside the json string.
You can do something like this:
$str = '{"messages":[{"a":"a","a":"","a":"Title : Test Image","a":"+923346455485"},{"a":"a","a":"","a":"Title : Test Image","a":"+923346455485"},]}';
if (!empty(strrpos($str, '"},]'))) {
$str[strrpos($str, ',', strrpos($str, '"},]'))] = '';
}
echo $str;
But I strictly advise against this and suggest you to replace the code where this string is formed in the Backend assuming you are trying to construct a JSON string.
Hope this helps.
您也可以尝试:
$string = substr_replace($string, '', strrpos($string, ','), 1);
