Php practice day 10 _ PHP Tutorial

The tenth day of php practice. Today, the front-end of the waterfall message board is finished. let's take a look. the serialize () serialized unserialize () deserialized functions are compiled into c. Today, the front-end of the waterfall message board is finished. 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.

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