Casting an Array with Numeric Keys as an Object

Question

I was poking around PHPs casting mechanism, and ran into an odd case when casting an array as an object

$o = (object) array(\'1\'=>\'/foo/bar\');   
$o =          


        

Answer 1

I think you get an error because casting an integer key of an array to an object / subobject will break the naming conventions of PHP varibles.

Tips:

• Decide before hands whether you want to have an OBJECT or an ARRAY
• Be careful with type casting (e.g. (object) array(1=>'string') do not do such things)
• Use castings for validation and not to convert things
• Avoid using objects as "fake" arrays
