在PHP中使用`/`作为数组索引，然后强制转换为对象

Question

I have an array that is defined as such:

$bar = array(
   '/' => 'foo'
);

I can convert it to a class (using $baz = (object) $bar ), and I don't get any errors. $baz contains the following: (via var_dump )

object(stdClass)#1 (1) {
  ["/"]=>
  string(3) "foo"
}

However, I can't seem to find a way to access the / property of $baz . I thought I could use $baz -> /; , but obviously there are syntax issues with that statement.

Thanks for the help!

Answer 1

Try this syntax

$baz->{'/'};

Curly braces may also be used, to clearly delimit the property name. They are most useful when accessing values within a property that contains an array, when the property name is made of mulitple parts, or when the property name contains characters that are not otherwise valid
