Multiple access type modifiers are not allowed¶

Description¶

Only one visibility option is necessary to set the visibility of a property. Two is overkill or could be impossible, so PHP reports it.

This message applies to private, protected and public options.

This message appears when compiling PHP 8.4+ code, with asymmetric visibility, against PHP 8.3 or older. In that case, protected(set) is not recognized as a token, and only the protected part is used, leading to the error.

There are similar messages for multiple readonly, or multiple static.

Example¶

<?php

class X {
     private private static A $b;
}

class Y
{
    public protected(set) string $name;
}

?>

Solutions¶

Drop the extra visibility, and keep only one.
Compile with PHP 8.4 and more recent.
Remove asymmetric visibility.
