object, contains ‘array1’.
$Obj -> array1 [12]; // works fine.
however, dynamically generating that array name – you can’t use square brackets…
$var = 'array1';
$Obj -> $var [ 12] ; // nothing. no error, but no result.
I had to do
$ar = $Obj -> $var ; // copy out array
$ar [12] ; // get value in array.
note:
$Obj -> $$var [ 12]; // fatal error, cannot access empty property
$Obj -> ($var) [12] ; // error, unexpected '[' or '('
This should work:
$Obj->{$var}[12]
