PHP Learning Route

In order to own the PHP system in-depth mastery, I through personal experience, as well as search online expert experience, summed up a PHP self-learning route planning, including actual combat drills, learning suggestions, master Advanced, FAQs and test summary of five pieces. It is a systematic learning plan and goal.
Avoid blindly learning, to improve some guidelines. Hope to self-pressurization, through the efforts to achieve the master level of cultivation. Tiandaochouqin, self-encouragement!

First, actual combat drills

Familiar with grammar &api---Read Zend, CI, wordpress Source, PHP Independent development projects, in-depth understanding of PHP engine implementation details, extension writing, performance optimization, etc.

(1 weeks) html+css HTML5+CSS3
(2-3 days) message board or Notepad, (add and revise, Array function database function)
(7 days) BBS or corporate website, (templates, paging, permissions) Phpchina master PHP lead the way-the problem summary and PHP manual
(1 months) Learn discuz foreign open source program (Zencert Joomla Drupal). Learn the essence of Phpchina.
(1 months) in-depth study of the ZF framework (increased deletion, access control, front-end template page, etc.)
(Long-term summary) to summarize their own small projects, using object-oriented thinking, structural optimization.
See Open source Framework source (This step please look for some small open source framework such as Ci,slim), enhance the understanding of MVC
More in-depth system learning (MySQL Linux C language javascript html CSS Redis etc.)

The most urgent combat:

(2 weeks) 3 stations (at least 20 art pages) PSD to HTML cut exercises.
(1 weeks) jquery combat drills
(January) Use ZF framework to develop modules to achieve flexible control

Knowledge points that must be mastered:

The database must be proficient in MySQL & SQL Server, and must be proficient in zendstdio operations.
Be proficient in phpmyadmin operation.
ADODB (Database Interface) +javascript+xml+ajax (asynchronous JavaScript and XML) +jquery (JS framework),
Familiar with OOP programming, Learning THINKPHP,ZF Framework, Learning smarty template engine, pear (PHP extension and application Library), prototype (design mode).
For Apache, you should also buy this administrator's manual for a good look.
At the same time a general understanding of Linux and so on. and server management operations.
-------------------------------------------------------------

Second, learning suggestions

"Function Reference" that part does not have to look at all, but the date and time, file system, other basic extensions, sessions, variables and types of the recommendations must be doubled, which introduces a lot of commonly used functions and classes.
These functions do not have to remember, as long as there is an impression on the line, in the future when used to come back to turn, with more natural to remember.
Start from the message book, then do a personal blog, and then do a more complex CMS, or small OA, the so-called experience, is actually the solution to the problem, from the project constantly thinking, you can continue to harvest!
Want to learn PHP OOP, directly on the Zend Framework 2, six months later you will feel that you have to step up a lot
Summary: Self-study is very important, practical project experience is also important. Do not assume that computer fundamentals are not important, and learning computer fundamentals is very useful for learning programming languages. As long as the more ruthless, more effort, there is no attack not broken things.

1 Basic PHP Programmer

Focus: LNMP Skilled (core is the basic operation of the installation configuration)
Objective: To complete basic LNMP system installation, simple configuration and maintenance, to be able to do basic PHP development of simple system, to support the development of a PHP function module in PHP medium-sized system.
Basic syntax array, string, database, XML, Socket, gd/imagemgk image processing, and so on; be familiar with the various APIs (MYSQL/MYSQLI/PDO) linked to MySQL, and know the solution to various coding problems Know the regular skilled PHP framework (thinkphp, Zendframework, Yii, YAF, etc.); understand the basic MVC mechanism and why you do it, a little bit about the differences between different PHP frameworks, and the ability to quickly learn an MVC framework. Be able to know the file directory organization in the development project, have the basic good code structure and the style, can complete the small system development and the medium system one module development work.

2 Intermediate PHP Programmer

Focus: Improve the skills for LNMP, can be more comprehensive to the LNMP have skilled application.
Objective: To set up the LNMP environment anytime, anywhere, to quickly complete the general configuration, to trace the most encountered development and online environment problems, to be able to independently assume the framework and development of the medium-sized system, to assume the development of a medium-sized module in a large-scale system;
In addition to the first-stage capabilities, installation configuration is free to install PHP and various third-party extensions of the compiled installation configuration; Understand most of the configuration options and implications of PHP-FPM (such as Max_requests/max_children/request_terminate_ Timeout and the like to affect the performance of the configuration), know the difference between the mod_php/fastcgi, in PHP has been able to master a variety of basic technology, but also a variety of in-depth PHP, including a deep understanding of PHP object-oriented/spl/syntax aspects of special features such as reflection , in the framework has read at least one of the regular PHP MVC framework Code, know the basic PHP framework internal implementation mechanism and design ideas; in PHP development has been able to skillfully use the conventional design pattern to apply development (abstract Factory/SINGLETON/Observer/Command chain/policy/adapter and other modes) , it is recommended that you develop your own PHP MVC framework to fully liberalize your development, allow yourself to understand the MVC pattern, and enable you to quickly upgrade your Business Project development, familiarize yourself with PHP's various code optimization methods, and familiarize yourself with most of the PHP security issues. Familiar with basic mechanism of PHP execution (Zend Engine/extended basic working mechanism);

3 Advanced PHP Programmer

Emphasis: In addition to the basic LNMP program, you can also have in-depth learning in a certain direction or field. (Depth dimension development)
Objective: In addition to the ability to complete basic PHP business development, but also to solve most of the deep and complex technical problems, and can be independently designed to complete the large-scale system design and development work, oneself can hold into a technical direction independently, in this piece of comparative professional. (such as MySQL, Nginx, PHP, Redis, and so on in any direction in-depth research)
As a basic core skill, we need more in-depth learning and application on the basis of the second stage. From the basic code application above, can solve the PHP development encountered 95% of the problem, understand most of the PHP skills, for most of the PHP framework can be quickly used in a day, and understand the pros and cons of various mainstream PHP framework, can quickly facilitate project development to do technology selection; In addition to the general second stage of knowledge, you will learn some of the more biased gate configuration options (PHP auto_prepend_file/auto_append_file), Includes some complex advanced configurations and principles in the extension (such as the memcache.hash_strategy in the memcached extension configuration, apc.mmap_file_mask/apc.slam_defense/in the APC extended configuration Apc.file_update_protection and so on), the working mechanism of PHP, including the PHP-FPM work mechanism (such as PHP-FPM under different configuration machine to open process number calculation and principle), Zend Engine has a basic familiarity (vm/gc/ Stream processing), read the basic PHP kernel source code (or read the related article), the most core data structure of PHP internal mechanism (basic type/array/object) implementation has the understanding, for the core infrastructure (zval/hashtable/ GC) with in-depth learning, ability to perform basic PHP extension development, understanding of some advanced knowledge of extended development (minit/rinit, etc.), familiarity with PHP and apache/nginx different communication interaction details (MOD_PHP/FASTCGI) In addition to developing PHP extensions, consider learning to develop Zend extensions to understand PHP from a lower level.


-------------------------------------------------------------

Third, the Master advanced

English good words recommended see https://tutsplus.com/(free version http://code.tutsplus.com/), although to pay (annual pay $15/month), but you will get more.
I have been paying for two years, the first to learn PHP, and then follow the framework of CI, laravel, and then learn jquery, ANGULARJS, etc., are in the actual application of the project, Ror, Nodejs also followed the study, but no opportunity to use.
Foreign masters do not only teach the teaching schedule reasonable, faster pace, do not waste your time and allow you to maintain a high concentration of attention, and can see the master's programming habits and tools, learning is the industry's newest things, such as the workflow of various editors, seconds to kill the country Phper video.

-------------------------------------------------------------

Five, debugging summary of my current common debugging methods:

PHP code debugging: Echo and Echo "<pre>"; Print_r (method);

Script JS is the alert mode, or Console.log. Console.log was originally the "patent" of Firefox, strictly speaking is installed after the firebugs Firefox unique debugging "trick".
This trick, IE8 learned, but use than firebugs trouble, only in the Debugging window (F12), the console.log can produce results, or error.

CSS debugging is to get the color blocks plus borders and so on. or after the page is written on the CSS, the transfer to the CSS file.

Log mode is used when printing is not possible. PHP is interpreted to perform weakly typed languages, unlike Java static strongly typed languages, where breakpoints can be set to perform traces. PHP If there is no log tool, is the black box difficult to troubleshoot the bug.

Please refer to: Logtofile ("My.Log", "Out page:". $_post [' cpage ']);
function Logtofile ($filename, $msg) {
$FD =fopen ($filename, "a");
$STR = "[". Date ("Y/m/d h:i:s", Mktime ()). "]". $msg;
Fwrite ($FD, $str. " \ n ");
Fclose ($FD);
}

There is a debugging Technology blog summary is quite comprehensive. See below.
