What are the PHP template application skills? For this problem, this article details the corresponding analysis and solutions, hoping to help more small partners who want to solve this problem find a simpler and easier way.

PHP after a long time of development, many users are very familiar with PHP, here I publish a personal understanding, and we discuss. I find that many PHP programmers, especially those who haven't studied PHP for a long time, don't know the essence of PHP. How did Perl become famous in the business world? Its powerful regular expressions. What about PHP? It is a language developed from Unix, and of course inherits many of the features of Perl, while C has the advantages.

Here, I want to write a PHP variable, array application skills and PHP regular expressions, PHP template application, later there is time to write PHP and COM, PHP and XML completely combined.

1. PHP template

Easy to write PHP static pages

How to use PHP Session

Summary PHP operator classification and usage

Easy to master PHP logical operator syntax and usage techniques

How to determine PHP operator precedence

If you know the function of regular expressions, you can know the template. What is PHP template? How about an example? Generally, when writing web pages and using background programs, program code is inserted into the web pages. such as PHP. This is a mix of HTML and PHP. The advantage of this is that the reading speed is fast, and the disadvantage is that if everyone works together to make a website, then non-programmers will not change the network. With templates, the division of labor can be most rationalized. Artists only do pages, programs only write background, and then close together. Excellent Jsp provides the ability to customize tags well done template functionality. How does mainstream PHP do that? This is done using regular expressions. You can download a PHPLIB online, which has a template.inc source code file under the PHP directory, that is, with P

2. Application skills of variables and arrays

(1)Array functions that a lot of people don't use much. foreach、list、each。Give a few examples, you should know. Example:

A pointer to a variable. This pointer is enclosed in double quotes to indicate that it is not a real pointer. Consider the following example:

It is called "pointer" because it has the same function as pointer in C language. But this is not a real pointer, it can only be understood in this way.

3. Regular expressions

Regular expressions are a very big subject, and Perl's power of regular expressions is well known. PHP is not weak either, it inherits Perl's regular expression rules and has its own set of rules. PHP's own regular expressions are mentioned here. Regular expressions are the most basic elements. Simply put, it is a set of rules used to determine whether other elements conform to their own rules, or whether they have the same characteristic description. Regular expressions begin with ^and end with $, and between these two symbols is the element that matches. For example, checking whether a phone number is a number for Beijing, using a regular expression to express it is "^010$." As long as the first 3 digits of the area code is 010, it is the number of Beijing, and the phone number behind it does not need to be in charge. Then, use the regular expression matching function ereg to judge, for example:

This is a regular expression. Beijing phone is 8 digits, then I want to know if this number is correct? What if he pressed the nine digit number? What if it's true or false? This is where the regular expression character cluster is used. Then the regular expression in the above example should be written like this: ^010[0-9]{8}$, which can determine whether the number conforms to the rule at the same time. Regular expressions have many applications, such as LBB, VBB forums in the posting of the so-called VBB code LBB code analysis, are completed with regular expressions.
