What exactly do you need to learn to learn PHP? _PHP Tutorial

Many people who learn PHP have never been able to figure out the difference between a PHP programmer and a Java programmer or a .net programmer. Let me tell you, they are all the same, there is no difference. The following content is based on the skills mastered by a Java programmer compared to PHP! Let me tell you, they are actually the same, they are just tools, there is no distinction between high and low. It’s just that you are not skilled and don’t know.

1. Syntax: You must be familiar with it. When writing code, the IDE editor should be able to know what kind of syntax error it is based on the error message when it reports an error on a certain line, and know how to correct it.
2. Commands: You must be familiar with some common commands and their common options in PHP. Be familiar with those commands and run php.exe -h yourself. If you have not used all of these commands, then you actually don’t know much about PHP.
3. Tools: You must be proficient in using at least one IDE development tool, such as: Eclipse, Netbeans, zend or editplus, ultraedit, including project management, setting of common options, installation and configuration of PHP plug-ins, and debugging.
4. API: The core API of PHP is very large, but there are some contents that I think you must be familiar with, otherwise it will be impossible to use PHP proficiently, including:

• Flexible use of more than 80% of the functions in the file directory processing function package.
• Flexible use of more than 80% of the functions in date and time functions.
• 100% content in the math function library.
• More than 60% of the content in the network library is relatively familiar with the functions of each function.
• More than 60% of the content under string processing functions, especially various processing functions.
• More than 90% of the content under the regular expression function, especially various regular processing.
• More than 40% of the content under some security libraries, if you have no contact with security, it is impossible to master PHP.
• XML processing, familiar with the advantages and disadvantages of SAX, DOM and JDOM and being able to use one of them to complete XML parsing and content processing.
• More than 80% of the content under the graphics and image function library, especially some image generation and processing.
• More than 90% of the content under MySQL database functions, especially functions for processing various data.
• More than 90% of the content under array processing functions, especially various operation processing functions.
• More than 80% of the content in other PEAR, PECL, and some extended class libraries, especially the processing of some commonly used classes.
• Find different function libraries for different needs.

Based on the above, I don’t find any difference between PHP and java. There are a lot of things to learn about PHP, Java, and .net.

If there are several languages ​​to choose from, then choose the one with the least difficulty in learning.

Don’t trust advertisements and the media. The only thing you can trust is your market.

Individuals can like one, two or even several languages, but they must not exclude any other language.

Attached is a conversation:

Impatient people tend to say: PHP language is not good, you should learn Java, C#, VB.NET: - It's you who can't do it! ?

Impetuous people tend to ask: Which one is better, PHP or Java, C#, or VB.NET; - both are good - as long as you can learn it well;

Impatient people tend to ask: What should I learn? - Don’t ask, just learn;

Impetuous people tend to ask: Is there any way to make money with PHP? - I suggest you rob a bank
