CodePudding user response：

You can concatenate a value into a string using the . concatenate operator.

<?php $url = "http://api.openweathermap.org/data/2.5/weather?q=" . $ipss . "&lang=fr&units=metric&appid=b5f11a80423d0d4dae64f1ec1a653edf"; ?>

use {} in double quotes

<?php $url = "http://api.openweathermap.org/data/2.5/weather?q={$ipss}&lang=fr&units=metric&appid=b5f11a80423d0d4dae64f1ec1a653edf"; ?>
