Display part of a variable IN PHP

I want to display part of a variable in PHP

176.241.85.42, 13.248.97.70

enter image description here

I want a code that displays the variable up to this comma and displays only what is before it

#In the sense of displaying the boldness before the comma only

>Solution :

You might use a regex pattern to achieve this, which is quiet simple

preg_match('/(.*),/', '176.241.85.42, 13.248.97.70', $result);
echo $result[0] ?? '';
