Drupal output a user name problem using drupal theme function output _ PHP Tutorial-php Tutorial

Drupal uses the theme function of drupal to output a user name. Today, I encountered the problem of using drupal to output a user name. I used drupal's theme function theme to output it. so I searched for information and found out the following content: 1. theme (username, today, I encountered the problem of using drupal to output a user name, which was output by the theme function of drupal. so I searched for the information and found out the following content:

1. theme ('username', array ('account' => $ log) calls a function. parameter 1 is hook, and parameter 2 is parameter

The code is mostly unavailable. view the address and click the open link.

2. during execution, go back to the template preprocessing function and the processing function are template_preprocess_username (& $ variables) and template_process_username (& $ variables) in theme. inc.

/**
* Preprocesses variables for theme_username ().

3. after processing these variables, the theme_username ($ variables) is implemented );
