I have many inline if's like this but only this one not working:

$border = $settings[$key]['border'] ? 'border-width:'.$settings[$key]['border'].'px;' : null;

$settings[$key]['border'] is "0" and gettype($settings[$key]['border']) return string.

I tried convert "0" again to string by adding (string) before $settings[$key]['border'].

    public static function GenerateStylesFromSettings($key, $settings){

            $css        .=  ($border)                               ? $border                                                   : null;

            $styles     =   ($css) ? 'style=\''.$css.'\'' : null;

            return $styles;

}

Not working. Edit: I need make that inline if as true to generate border-width: 0px.

CodePudding user response：

As string '0' is considered false in php, you should use another comparisons like:

null !== $settings[$key]['border'] ? 'value' : null;
// if value is always a string - compare with empty string
'' !==  $settings[$key]['border'] ? 'value' : null;
