create_function() deprecated. WordPress settings page error

Question

I have a function for the WordPress settings where the create_function() was used but when I updated the server to PHP7.2, and it says the function is deprecated.

I don't know what alternative to use.

Code

if ( isset( $section['desc'] ) && ! empty( $section['desc'] ) ) {
  $section['desc'] = '<div class="inside">' . $section['desc'] . '</div>';
  $callback = create_function( '', 'echo "' . str_replace( '"', '\"', $section['desc'] ) . '";' );
} elseif ( isset( $section['callback'] ) ) {
  $callback = $section['callback'];
} else {
  $callback = null;
}

Just create an anonymous function to use as a callback:

Your line:

$callback = create_function( '', 'echo "' . str_replace( '"', '\"', $section['desc'] ) . '";' );

Could be replaced with:

$callback = function() use($section) { echo str_replace ('"', '\"', $section['desc']); };
