The Tenth Day of PHP Practice_PHP Tutorial
今天算是把瀑布流留言板前台后台做完了.先上图欣赏下吧.
今天学习到的东西
serialize()串行化
unserialize()反串行化
由这两函数,编写出了 config_set() 和 config_get() 两函数.
[php]
/**
* 用于写出数组配置
*/
function config_set($fileName,$arr_var){
file_put_contents($fileName, serialize($arr_var));
}
/**
* 用于读出配置,返回值为设置出去的数组
*/
function config_get($fileName){
if(file_exists($fileName)){
return unserialize(file_get_contents($fileName));
}
}
/**
* 用于写出数组配置
*/
function config_set($fileName,$arr_var){
file_put_contents($fileName, serialize($arr_var));
}
/**
* 用于读出配置,返回值为设置出去的数组
*/
function config_get($fileName){
if(file_exists($fileName)){
return unserialize(file_get_contents($fileName));
}
}调用方法
[php]
$config = array(
'title' => '瀑布流留言板',
"b"=>'aaaa'
);
config_set("data.php",$config);
$config=config_get('data.php');
var_dump($config);
$config = array(
'title' => '瀑布流留言板',
"b"=>'aaaa'
);
config_set("data.php",$config);
$config=config_get('data.php');
var_dump($config);
2.jquery选择器中'[]'的使用方法,和 removedClass 移除样式, addClass 添加样式,利用这个可以轻松做出高亮效果
var focus_li = $("#menu li[class!=nav-header]");
focus_li.click(function() {
focus_li.removeClass("active"); //把所有高亮样式去掉
$(this).addClass("active"); //给被点击的添加高亮样式
3.关于session,unset($_sesstion),这是清除不了的.要使用 session_unset()
4.前台的留言表单重新编写chrome浏览器效果好,IE的话特效少,不太漂亮
[html]
5.后台的下拉按钮,很漂亮噢.哈
