php - Dynamically choosing an object's property?

Question

I'm trying to dynamically select a property from an object, but I'm not sure how to accomplish this.

$prop = '12345';
$object->$prop

in effect trying to recreate this:

$object->12345

You need to use the curly braces if you want to access that way..

$myobject = new stdClass;
$prop = '12345';
$myobject->$prop = $prop;
echo $myobject->{12345}; //"prints" 12345

or simply echo $myobject->$prop will do.

If you access it as echo $myobject->12345;, below error will be thrown.

PHP Parse error: syntax error, unexpected '12345' (T_LNUMBER), expecting identifier (T_STRING) or variable (T_VARIABLE) or '{' or '$'
