The so-called tag is a special symbol (for example) used to make it easier to distinguish from other content. In PHP, when parsing a file in .php format, PHP looks for the opening and closing tags, and any text between the two tags is interpreted as PHP code. Any text outside the tag is considered regular HTML, which means that PHP tags can isolate PHP code from HTML.

There are four markup styles in PHP, which will be introduced one by one below.

1. XML style

This is the most frequently used markup style, and it is also the markup style recommended by PHP.

This style is enabled by default and cannot be disabled, so it is guaranteed that this style of markup can be used on all servers, especially when writing applications for different server environments.

2. Short style

To use this markup style, which is the simplest, you need to enable the short_open_tag option in the configuration file php.ini. However, this style of markup is not recommended in day-to-day development, because it is no longer supported in the default settings of many environments.

3. ASP style (removed)

This markup style is the same as that of ASP or ASP.NET, which is disabled by default. If you want to use it, you need to enable the asp_tags option in the configuration settings.

However, this markup style is no longer supported in PHP7, so you can understand it.

4. SCRIPT style (removed)

Echo''

This markup style is the longest, and readers will be familiar with it if they have used JavaScript or VBScript.

This markup style is no longer supported in PHP7, so you can understand it.

Note: if the content of the file is pure PHP code, it is best to omit the PHP closing tag at the end of the file. This avoids misoperations such as accidental insertion of spaces or line breaks after the PHP closing tag, resulting in unexpected spaces and line breaks in the output.
