Re: [PHP] Implementing strict types
On 1 March 2011 04:40, Paul McGarry p...@paulmcgarry.com wrote:
I am looking at implementing something roughly equivalent to strict
typing for a part of my code.
Has anybody else had a go at such a thing?
I have some data types which I'm implementing as classes (base types
like int but also more specific types like country) and I'd like
to be able to use them as normal variables (as far as assigning and
retrieving it's value goes) with 'magic' happening inside the class
for validation and normalisation (eg accepting any ISO style country
code on assignment but standardising on alpha 2 on output).
I am aware of the capability to override the assignment operator for a
property of an object, ie use the __set() magic method so that
$object-var='hello';
is equivalent to:
$object-__set('var','hello');
allowing the __set() method to do some funky stuff.
Is there a similar capability to override the assignment operator on
the object itself, ie have:
$object='hello';
handled by a method on the $object?
Similarly the __toString() magic method would cover part of the
getter overriding, but it seems to be a special case override that
only works within specific string functions rather than a generic
getter override.

There is __invoke, but that is for ...
$instance()
The problem is (hopefully) explained in ...
$instance = 'something that needs to be passed to instance and not
assigned to instance';
How do you differentiate between the two assignments (one to the
variable and one to be processed by the instance) ?

Could it be that the addslashes is creating a \0 (null) value? That
might screw up the decryption routine.

Just a WAG, but when I first was working with mcrypt, it would append
spaces to the encrypted value. I would have to TRIM() everything for
processing or decryption. BTW, we also elected *not* to store card
numbers, only the last 4 digits.

But here goes. Your first field id is an auto_increment field this means the counter goes up by every insert. Normally this will start at 1 not 0. So either change the 0 to a higher number or remove the auto_increment part before you import change the 0 after and alter the table to put back auto_increment -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.10 (GNU/Linux) iQIcBAEBAgAGBQJNbfOvAAoJEMffsHAOnubXC7UP/1k5qA4TDxDnUKrYZLV/rl9s bLRPTQ21riFMIzt0ne14No4+MTwjNtfVAdSnjpCWEZP+Y2MEixaiz8gIcOt9GIOD f9QPJZFEIcVADs3lqeS88eqdgRBNiYy3x2PHyslR3jtuaeFrRvxOLBTgBISq6Ih4 Dd5nRCbo6WObQ5e26HhbDeMJDAnOw4iQMjpoxc6UD9syxkJrORYw6XFvEmJA/QNF RDTNIO7P62ROamGor8urmPdfIemFLyqjD5YAQ64O6aWVHp0ehjO4l1xPWCeI84sV 2g8C3yqi06UjYOE8NHrf64VYcQtvLFkJbzGT6mmPwEP0gBdqX6o2YDwnudv7+APN F5zoVBv/7wygFaP+P0zgJ+EWVML35VfJFuq5VCH3CUk1hROS4X/JtsNXdVkAbaFA BpEhQ4jN0x/34HrI1cWjEUwaUuU6m9XoMIuO+1tQRLFatEW9I5z1c3hrJsPUNImX qSxEGLAZyA7tex++4YFn8DZXWz4mdllI7yejRe0nl1vl4Nn1+t2se/vF0TfZAGdB HgDeUWTdY/N2KeT4z9gPjGEDlRp8Wqo13Sv1yVhzWDdAJQdWaH8+Kk0GCI0jBrgT Pthmjr0e4bKCW19SJtL7/mTRU12qX/kbjMG5JqIh1ixn72qgqcvkTjgvEeQ1Y0DM xBBFUUedwoKevRJI05/2 =mdri -END PGP SIGNATURE- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
