Description:
------------
---
From manual page: http://www.php.net/language.types.array
---
While using an echo command with a double apostrophe argument that includes an array variable, the name of the Array object is outputted rather than the actual value for the array item

Test script:
---------------
<?php

Class T {
        private $a = array("c","d") ;

        public function f() {
                return "$this->a[1]" ;
        }
}

$c = new T() ;
echo $c->f() ;



Expected result:
----------------
d

Actual result:
--------------
Array[1]

You need to use the complex syntax: http://www.php.net/manual/en/language.types.string.php#language.types.string.parsing.complex — "{$this->a[1]}" will work as expected.

As the manual says about the simple syntax: "Similarly, an array index or an object property can be parsed" — you can't have both an object property and an array index.

Closing NaB.
