"Turn" June 2012 26–PPS Network TV PHP engineer the latest questions

every interview is a contest, and the interviewer, but also you and yourself!

Although the job interview is a PHP engineer, the topic is not limited to PHP，not even a lot of PHP problems! Inner peace! I hope I can give you a hint of help.

PPS Network TVface Test (PHPengineer) Non-answer!!! Please consult Google God yourself.

A written examination of four sheets of paper. It's late, so there's only half an hour left! I was shocked. With the same seat to the written test of a few buddies joke: this is more than the college entrance exam! So most hours!

But one of the Buddies seriously entered the state, take out the mobile phone in Baidu! Feed! Handsome, so many algorithm problems, Baidu useful? We'll have an oral interview later!

The written examination is not too difficult.

Oral examination: (the impression is as follows.) I will not, the interviewer finally also gave me a supplement, more humane. By the way, one of the interviewers doesn't talk, so look at me! Another question. I can't afford to hurt myself.

What is the difference between establishing a joint index on a, b, and B and a?

Answer: Well ... I think the optimizer will not use this index when making a select query. And then it's time to play!

Add: You are a little close, but the concept is a little confused! If the index of the table is set to A, B, in a single where condition, only a condition is not a problem, but only the B condition, MySQL will not enable this index query. Because the index is a tree, only the first one satisfies him to index the second value Ah, you say right?

tell me about these magic functions you wrote, right?

A: Yes, I wrote these, I kinda can't remember what's the other name? It's just a way to call a method that's not in the object!

Call It!

yes! There's a callstatic, right? Oh.

So, what do you mean by call, where is your main application?

A: I wrote the database in the abstraction layer, to achieve a consistent database operation, similar to the thinkphp in the framework of the one. Call those non-existent where,select methods, the parameters are hidden in the property, return to the object, very good!

PS:During the interview, technical questions, most of the time I was fluent. To the HR, is a beauty! , I was really asked the sweating like Ah! Multiple speechless! I can only giggle at the time!

Why come to Shanghai? You basically jump once a year slot, say the first 2 times why you job-hopping? Why don't you want to stay in the company? You've only been here for a few months! And why Choose PPS? What is your most important thing about business?

Just interview you is our Technical manager, said you are good, is the salary open high, what do you think?? Is K coming?

We said Ah, you basically match is the salary is high? What do you think?

You should also interview several enterprises at the same time, if finally received the offer, how do you choose?

Why?

Omit n words!

Something, this beautiful hr really a bit domineering ah!
