Array- und String -Offset -Zugriffssyntax mit lockigen Klammern ist veraltet
Let's say you have something like this in your code:
$str = "test";
echo($str{0});
since PHP 7.4 curly braces method to get individual characters inside a string has been deprecated, so change the above syntax into this:
$str = "test";
echo($str[0]);
