There is a very strange error when using associative array naming within quotes, have a look here. This is based on the PHP5 May 5th 17:30GMT build.

In PHP 4.3.1


$arr = array("hello" => "hello world");
echo "$arr['hello']";


The above code does not output any information. The quotes have something to do with this.


$arr = array("hello" => "hello world");
echo $arr['hello'];


This above code fragment will print "hello world".

The usage that is consistent always is not using single quotes :


$arr = array("hello" => "hello world");
echo "$arr[hello]"; // echo $arr[hello]; executes!

The above is still acceptable and does not generate any error. Not even a notice if it is turned on, so it most likely an output related bug.

Now coming to PHP5!


$arr = array("hello" => "hello world");
echo "$arr[hello]"; echo $arr[hello]; exectues!


The above code works fine, with and without the quotes.


$arr = array("hello" => "hello world");
echo "$arr['hello']"; // echo $arr['hello']; executes!


This code does not work if the quotes are present, works when the quotes are removed!
