Function create_function() is deprecated in php7.2

Question

Getting Function create_function() is deprecated Error in laravel 5.4 and php 7.2. Not able to find solution.

please see below code

 public static function delimiterToCamelCase($string, $delimiter = '[\-\_]')
{
    // php doesn't garbage collect functions created by create_function()
    // so use a static variable to avoid adding a new function to memory
    // every time this function is called.
    static $callback = null;
    if ($callback === null) {
        $callback = create_function('$matches', 'return strtoupper($matches[1]);');
    }
    return preg_replace_callback('/' . $delimiter . '(\w)/', $callback, $string);
}

please help.

create_function has been deprecated as of php 7.2. Instead you can use anonymous_function.

if ($callback === null) {
     $callback = function ($matches) {
         return strtoupper($matches[1]);
     };
}
