You cannot learn programming by only looking at examples. Please refer to the recommended text book (Murach's PHP and MySQL 2nd Edition) for detailed explanations.
After you finished going through all examples on this page, some AJAX examples can be found on this ajax page.

PHP origionally stood for Personal Home Page, but it now stands for the recursive acronym "PHP: Hypertext Preprocessor". - Quote from wikipedia.org

MVC pattern example (eg010, php textbook ch. 5, half of ch. 5 example - product manager only):

Controller = index.php
Model = database.php; product_db.php; category_db.php
View = product_list.php; product_add.php; database_error.php

Php etc file Txt file Description Video
step 0 create MySQL database, create MySQL user for web access
eg008_create_db.sql eg008_create_db.txt - done in eg008
- ER diagram		 done in eg008
create 4 subfolders:
- product_manager/
- model/
- errors/
- view/		 index.php is put in "product_manager/" subfolder    
step 1 create Model (Mvc)= represent the data
model/
database.php		 database.txt - create model folder
- connect to database		  
step 1 create View (mVc)= user interface
errors/
database_error.php

view/
header.php
footer.php

main.css		 database_error.txt


header.txt
footer.txt


main.css		 - create errors folder
- create file, database_error.php includes header.php and footer.php

- create view folder
- create files, header.php and footer.php includes main.css

  
step 1 create Model (Mvc)= represent the data
model/
category_db.php
category_db.txt
 - create files
- create function "get_category_name()" to get default category name from database table		  
step 1 create Controller (mvC)= receive user request
product_manager/index.php index.txt - include files, use function "get_category_name()" to get category name  
step 2 expand MVC, add program functions to list products
step 2 update/create Model (Mvc)= represent the data
model/
category_db.php
category_db.txt
 - update
- create function "get_categories()" to get all category names from database table		  
model/product_db.php product_db.txt - create new file
- create function "get_products_by_category()" to get all product names		  
step 2 update/create Controller (mvC)= receive user request
product_manager/index.php index.txt - update
- include product_db.php file
- use function "get_categories()" to get all category names
- use function "get_products_by_category()" to get all product names
- include product_list.php (new file below)		  
product_manager/product_list.php product_list.txt - create new file
- include ../view/header.php
- include ../view/footer.php
- use $categories from index.php, display
- use $category_name and $products from index.php, display, create delete buttons, using post action
- create add product link, using get action		  
step 3 expand MVC, add program functions to delete products
step 3 update Controller (mvC)= receive user request
product_manager/index.php
 index.txt
 - update
- handle delete if action is delete_product
- use function "delete_product()" to be created in model/product_db.php below		  
step 3 update Model (Mvc)= represent the data
model/product_db.php product_db.txt - update
- add function "delete_product()" to delete		  
step 4 expand MVC, add program functions to show add product form
step 4 update Controller (mvC)= receive user request
product_manager/index.php
 index.txt
 - update
- handle add if action is show_add_form
- use function "get_categories()" which has been create in step 2 in model/category_db.php
- include file product_add.php		  
product_manager/product_add.php product_add.txt - create new file
- handle add if action is show_add_form
- include ../view/header.php
- include ../view/footer.php
- use $categories from index.php, display
- capture user input, submit to index.php, action is add_product as hidden field
- add link to index.php, action is list_products		  
step 5 expand MVC, add program functions to add product
step 5 update Controller (mvC)= receive user request
product_manager/index.php
 index.txt
 - update
- handle add if action is add_product
- check empty field, if yes, include file ../errors/error.php
- else, use "add_product()" function in model/product_db.php
- send it back to self, keep $category_id
 
step 5 create View (mVc)= user interface
errors/
error.php		 error.txt
 - create file, error.php
- include ../view/header.php
- include ../view/footer.php
- show $error from index.php
 
step 5 update Model (Mvc)= represent the data
model/product_db.php product_db.txt - update
- add function "add_product()" to add to database

 eg102_dynamic_textbox.txt use php to dynamically create textboxes, and use another php file eg101_dynamic_process.php (text file) to pick up input (same as above).  
Upload file
eg051.php eg051.txt    
eg051_upload.php eg051_upload.txt need to create sub_folder "upload_folder" to save files
