Subject: PHP problem with array keys / pointers
Hi all,
I've a problem thats been bothering me for a week now
I have an array $animals
keys and values like this
1 => cat
2 => dog
3 => mouse
4 => horse
I want to be able to access them using either a key or a pointer, however
the key/pointer will be a variable
without variables, if I want dog, I can either use $animals[1] or
$animals['2']
but with a variable , eg. $x = 2
$animals[$x] will always give me 'mouse'
what syntax do I need to use for $animals[$x] to give me 'dog' when $x=2
?
I would think that you have string keys instead of integer ones. Perhaps
there is some whitespace in the variable using to set the key?
For example:
$array = array(' 2' => 'dog'); // there is a whitespace before the number 2
will set the element of ordinal number 0 and key ' 2' to 'dog'. To get
that value you would either ask for $array[0] or $array[' 2'].
Doing a print_r() or var_dump() on the array will let you know what the
actual contents of both the keys and values are.
