associative array

[[deleted]]

Just found out that negative number is not allowed as the key in the array. e.g.

$array = array ( 50 =>"fifty", -25=>"minus" );
doing either
echo "$array[50]\n";
or
echo "$array["50"]\n";

and you will get expected "fifty" output.

But parse error when
echo "$array ["-25"]\n";
or
echo "$array[-25]\n";

I have an array describing error codes that has some negative numbers pointing to their corresponding message. I have to change the negative number to positive in order to print the message.

$testarray = array(-1 => 'err -1', -3 => 'err -3');

print_r($testarray);

You're wrong. Try NOT enclosing your $array[-25] in quotes.

If you code right, you're negative keys will work fine.
