Getting a result I don't understand.
Why does the non-existent key in the array below evaluate to the first char of the array value?
$foo = '' ; $foo['one']['two'] = 'test-value' ;
// Evaluates to: string(1) "t" var_dump( $foo['one']['two']['three'] ) ;
// Evaluates to NULL, as expected var_dump($foo['one']['two']['three']['four'] ) ;
Can anyone enlighten me?
Strings are arrays. PHP probably takes the string 'three' and converts it to a integer to see what "key" of the string you're requesting.
$foo = 'bar'; echo $foo[1]; //should echo 'a'
Does that help or do you need a deeper explanation (that I probably can't provide!) ;)
