Php practice day 10

Today, we have finished the front-end of the waterfall message board. Let's take a look.

 

 

 

 

 

 

 

What I learned today

Serialize () serialization

Unserialize () deserialization

The two functions compile the config_set () and config_get () functions.

[Php]
/**
* Used to write out array configurations
*/
Function config_set ($ fileName, $ arr_var ){
File_put_contents ($ fileName, serialize ($ arr_var ));
}
/**
* Used to read the configuration. The returned value is the set array.
*/
Function config_get ($ fileName ){
If (file_exists ($ fileName )){
Return unserialize (file_get_contents ($ fileName ));
}
}

/**
* Used to write out array configurations
*/
Function config_set ($ fileName, $ arr_var ){
File_put_contents ($ fileName, serialize ($ arr_var ));
}
/**
* Used to read the configuration. The returned value is the set array.
*/
Function config_get ($ fileName ){
If (file_exists ($ fileName )){
Return unserialize (file_get_contents ($ fileName ));
}
} Call Method

[Php]
$ Config = array (
'Title' => 'waterfall message board ',
"B" => 'aaa'
);
 
Config_set ("data. php", $ config );
 
 
$ Config = config_get ('data. php ');
 
Var_dump ($ config );

$ Config = array (
'Title' => 'waterfall message board ',
"B" => 'aaa'
);

Config_set ("data. php", $ config );
 

$ Config = config_get ('data. php ');

Var_dump ($ config );
2. How to Use the '[]' in the jquery selector, remove the style from the removedClass, and add the style to the addClass to easily highlight the style.

Var focus_li = $ ("# menu li [class! = Nav-header] ");
Focus_li.click (function (){

Focus_li.removeClass ("active"); // remove all highlighted styles
$ (This). addClass ("active"); // Add a highlighted style to the clicked

 

3. For session, unset ($ _ sesstion) cannot be cleared. session_unset () is used ()

 

4. Rewrite the chrome browser in the message form at the front end. The effect of IE is less special and not very nice.

[Html]
<Form class = "form-horizontal" action = "index. php? M = index & a = add "method =" post ">
<Div class = "control-group">
<Label class = "control-label" for = "content"> message content </label>
<Div class = "controls">
<Textarea class = "span8" rows = "3" id = "content" name = "content" placeholder = "Enter your message content"> </textarea>
</Div>
</Div>
 
<Div class = "control-group">
<Label class = "control-label" for = "userName"> nickname </label>
<Div class = "controls">
<Input class = "span2" type = "text" id = "userName" name = "userName" placeholder = "enter your name">

Contact info

<Input class = "span2" type = "text" id = "email" name = "email" placeholder = "QQ, Email, and mobile phone">

<Input class = "btn-info" type = "button" id = "submit" name = "submit" value = "">
 
</Div>
</Div>
 
</Form>

<Label class = "control-label" for = "userName"> nickname </label>
<Div class = "controls">
<Input class = "span2" type = "text" id = "userName" name = "userName" placeholder = "enter your name">

Contact info

<Input class = "span2" type = "text" id = "email" name = "email" placeholder = "QQ, Email, and mobile phone">

<Input class = "btn-info" type = "button" id = "submit" name = "submit" value = "">

</Div>
</Div>

</Form>

5. The drop-down button in the background is very beautiful.

[Html]
<Div class = "span4" style = "text-align: right">
<Div class = "btn-group" style = "text-align: left">
<Button class = "btn-danger dropdown-toggle" data-toggle = "dropdown">
Welcome back <{$ userName}> <span class = "caret"> </span>
</Button>
<Ul class = "dropdown-menu">
<Li> <a href = "index. php"> View websites </a> </li>
<Li class = "divider"> </li>
<Li> <a href = "admin. php? M = admin & a = ulogin "> log out </a> </li>
</Ul>
</Div>
</Div>

<Div class = "span4" style = "text-align: right">

<Button class = "btn-danger dropdown-toggle" data-toggle = "dropdown">

<Ul class = "dropdown-menu">
