Use

1. Introduction of smarty class library

two。 Instantiate smarty object

3. Initialization parameter

Template_dir template storage directory

Compile_dir compilation directory

4. Allocation variable

5. Parsing template

Comment {* this is the content of the comment *}

Ignore smarty parsing {literal} {/ literal}

Example:

/ / the first step is to move to the smarty class

Require'. / libs/Smarty.class.php'

/ / step 2 instantiate the object

$s = new Smarty

/ / step 3 initialization

$s-> template_dir ='. / View'

$s-> compile_dir ='. / View_c'

$pdo = new PDO ('mysql:host=localhost;dbname=pass;charset=utf8','root','')

$stmt = $pdo- > query ('select * from news')

$res = $stmt- > fetchAll (PDO::FETCH_ASSOC)

/ / var_dump ($res)

/ / step 4: assign variables

$s-> assign ('title',' News Management system?')

/ / $s-> assign ('name',' what?')

$s-> assign ('res',$res)

/ / step 5 parse the template

$s-> display ('add.html')

/ / create view files to store and change web pages, view_c conversion files

Add.html

{extends file='index.html'}

{block name='title'}

News add page

{/ block}

{block name='content'}

Release the news

# # smarty

/ / the first step is to move to the smarty class

Require'. / libs/Smarty.class.php'

/ / part II instantiates the object

$s = new Smarty

/ / initialization of part III

/ / template directory initialization, template storage directory

$s-> template_dir ='. / View'

/ / compile directory

$s-> compile_dir ='. / View_c'

$pdo = new PDO ('mysql:host=localhost;dbname = pass;charset = utf8','root','')

$stmt = $pdo- > query ('select * from stu')

$res = $stmt- > fetchAll (PDO::FETCH_ASSOC)

/ / step 4: assign variables

$s-> assign ('a template of title','smart')

$s-> assing ('name','mingzi')

$s-> assing ('res','$res')

/ / step 5 analyze the template

$s-> display ('2.html')

2.html change

Mysqli

/ / Import file /

Define ('HOST','localhost')

Define ('USER','root')

Define ('PWD','')

Define ('DBNAME','pass')

Define ('UTF','utf8')

$link = @ mysqli_connect (HOST,USER,PWD) or die ('connection failed')

Mysqli_select_db ($link,DBNAME); / / Select a database

Mysqli_set_charset ($link,UTF); / / character set

$sql = 'select * from news order by id')

$result = mysqli_query ($link,$sql)

/ / query result auxiliary function

Mysqli_num_rows ($result) > 0

Mysqli_fetch_assoc ($result) gets the associative array

Mysqli_close ($link) / / shut down the database
