下面引用何老师的一段经典的话：

大多数时候
缺乏自信是好事
因为缺乏自信会让你不知不觉之间积累很多知识和经验
这样来的自信更扎实
以前我工作的时候
天天期望能碰上个高手
然后自己在高手带领下工作
结果盼望了十年
突然发现其实高手都不存在
自己就是自己心里的高手

我想到那年轻时候那执着的梦想~

有一种东西，它会在某个夏天的夜晚象风一样突然袭来，让你措不及防，无法安宁，与你形影相随，挥之不去，我不知道那是什么，只能称它为爱情。

PHP is simultaneously the most infuriating and joyful languages I’ve ever worked with. I say “infuriating” primarily because the function names are so inconsistant. Despite the fact that I use it almost everyday, I still have to think to myself “Is it str_pos or strpos? str_split or strsplit?” On the other hand, occasionally I’ll stumble across a gem that perfectly solves the problem at hand with a single line of code.

Here’s a short list of cool features that might have slipped under your radar as well:

1. Use ip2long() and long2ip() to store IP addresses as integers instead of strings in a database. This will reduce the storage space by almost a factor of four (15 bytes for char(15) vs. 4 bytes for the integer), make it easier to calculate whether a certain address falls within a range, and speed-up searches and sorts (sometimes by quite a bit).
2. Partially validate email addresses by checking that the domain name exists with checkdnsrr(). This built-in function checks to ensure that a specified domain name resolves to an IP address. A simple user-defined function that builds on checkdnsrr() to partially valid email addresses can be found in the user comments section in the PHP docs. This is handy for catching those occasional folks who think their email address is ‘joeuser@wwwphp.net’ instead of ‘joeuser@php.net’.
3. If you’re using PHP 5 with MySQL 4.1 or above, consider ditching the mysql_* functions for the improved mysqli_* functions. One nice feature is that you can use prepared statements, which may speed up queries if you maintain a database-intensive website. Some benchmarks.
4. Learn to love the ternary operator.
5. If you get the feeling that you might be reinventing the wheel during a project, check PEAR before you write another line. PEAR is a great resource that many PHP developers are aware of, yet many more are not. It’s an online repository containing over 400 reusable snippets that can be dropped right into your PHP application. Unless your project is trully unique, you ought to be able to find a PEAR package that saves at least a little time. (Also see PECL)
6. Automatically print a nicely formatted copy of a page’s source code with highlight_file().This function is handy for when you need to ask for some assistance with a script in a messageboard, IRC, etc. Obviously, some care must be taken not to accidently show your source when it contains DB connection information, passwords, etc.
7. Prevent potentially sensitive error messages from being shown to users with the error_reporting(0) function. Ideally error reporting should be completely disabled on a production server from within php.ini. However if you’re on a shared webhost and you aren’t given your own php.ini, then your best bet is to add error_reporting(0); as the first line in each of your scripts (or use it with require_once().) This will prevent potentially sensitive SQL queries and path names from being displayed if things go awry.
8. Use gzcompress() and gzuncompress() to transparently compress/decompress large strings before storing them in a database. These built-in functions use the gzip algorithm and can compress plaintext up to 90%. I use these functions almost everytime I read/write to a BLOB field within PHP. The only exception is when I need full text indexing capabilities.
9. Return multiple values from a function with “by reference” parameters. Like the ternary operator, most PHP developers who come from a more formalized programming background already know this one. However, those who’s background is more HTML than Pascal, probably have wondered at one time “how do I get multiple values back from a function I wrote, even though I can only use one return value?” The answer is that you precede a variable with “&” and use it “by reference” instead of “by value”.
10. Fully understand “magic quotes” and the dangers of SQL injection. I’m hoping that most developers reading this are already familiar with SQL injection. However, I list it here because it’s absolutely critical to understand. If you’ve never heard the term before, spend the entire rest of the day googling and reading.

“认真”意味着做人做事不马虎、不消极、不推脱、不懒惰、不自卑、不偏颇、不浮躁、不气馁、不放弃。如此简单的两个字，又有多少人能够真真做到呢？
