PHP 5.3 Certification (200-530)

I will attend the Zend PHP 5.3 Certification exam on Tuesday, Dec. 6, St. Nicholas Day. This is a important step to evaluate my php skills :) The exam covers many topics like PHP basics, functions, web features, OOP, security, I/O and databases (specially MySQL) in multiple choise questions.

I don’t think that I get a Santa Claus gift, therefore my exam strategy is to pass through all the questions answering what I can, as fast as I can, marking certain questions that I’m unsure of for later review.

EXAMPLE:

What will be the output of the following code snippet?

echo (int) ((0.1 + 0.7) * 10);
  1. The PHP script will return an error message.
  2. 7
  3. 10
  4. 8

ANSWER: B.


What will be the output of the following code snippet?

echo 'hello ' . 1 + 2 . '34';
  1. 0
  2. hello1234
  3. hello334
  4. 234

ANSWER: D.

so pretty neat PHP type converts!

Yay I have passed the exam. In conclusion the ZCE exam was a good experience for me. Some PHP experience that escaped my attention were reminded by the learning days before the exam. So I can use it well for my work.

iPhone 4 Home Button does not respond

Holy crap my iPhone 4 home button did not responding anymore in the last days. So like me many users are upset about it in forums. After numerous idiotic solutions I found a workaround that does work and has worked ever since. I can’t believe that but if I plug my USB charging cable into the iPhone and press the right part where it is plugged up towards the screen, just a little, bam that helped!

But Apple…wtf…the only most used mechanical button installed so bad?

An alternative solution is to activate the “AssistiveTouch” in Settings -> General -> Accessibility. This will bring up a transparent round button at the bottom right of the screen with accessibility helper especially a home button option that works just like as the physical home button.

MySQL table duplicates

No big magic but I’ve needed some times the following MySQL statement to find table duplications in the database.

SELECT id, name, vendor_number, COUNT(vendor_number) AS count
FROM adr_contact
GROUP BY vendor_number
HAVING COUNT(vendor_number) > 1

With the “Having” clause I can use aggregate functions on the WHERE part.
This snippet is pretty helpful to dedupe a MySQL table.

How thin can a computer be?

I got the new Macbook Air. Thanks to my friend christian – my wait is over. It’s my first private mac ever :)

This new Apple flounder packs a 13″ screen and keyboard into a aluminum body that’s quite thin and light. And it has a 128GB solid-state drive with no moving parts instead of a hard disk. Apple’s brand new MacOSX 10.7 Lion is pre-installed and I will it use as my new lightweight mobile development machine.
