With the popularity of smartphones and the emergence of WeChat applets, drawer menus have become a common UI design. This design can provide a better user experience and make the interface simpler.
In this article, we will introduce how PHP implements the drawer menu function in WeChat applet. In this article, we will use WeChat applet and PHP as examples.
- Create a page for the WeChat applet
First, we need to create a page containing a menu in the WeChat applet. In this page, we will use the
<!-- 菜单内容 -->
< ;/view>
<image class="menu-image" src="{{showMenu? '/images/close.png':'/images/menu.png'}}"></image>
In this code snippet, we have created a container view and a button view where if the user clicks on the button, the toggleMenu function is triggered. In the toggleMenu function, we will use the showMenu variable to determine whether the menu is displayed. If the menu is shown, we will hide it and change the image of the button; if the menu is hidden, we will show it.
- Create PHP backend code
In this step, we need to create a PHP script to get the menu data and return it to the applet page.
Assume that our menu data is stored in a file named menu.php and is output in JSON format. Below is an example of a PHP script that can get menu data and return it.
header('Content-type: application/json');
$menu = file_get_contents('menu.php');
echo $menu;
?>
In this example, we first define the header of "Content-type: application/json", which means that we will return data in JSON format. Next, we use the "file_get_contents" function to read the data in the "menu.php" file. Finally, we return the data to the mini program page through the "echo" function.
- Render data into the mini program page
The last step is to render the menu data into the mini program page. We can use the
<navigator url='{{item.url}}'> <text class='menu-item'> {{item.text}} </text> </navigator> </block>
In this code snippet, we use the
Summary
In this article, we introduced how PHP implements the drawer menu function in WeChat applet. We first created an applet page containing a menu, and then created a PHP script to get the menu data and return it to the applet page. Finally, we use the

php把负数转为正整数的方法:1、使用abs()函数将负数转为正数,使用intval()函数对正数取整,转为正整数,语法“intval(abs($number))”;2、利用“~”位运算符将负数取反加一,语法“~$number + 1”。

实现方法:1、使用“sleep(延迟秒数)”语句,可延迟执行函数若干秒;2、使用“time_nanosleep(延迟秒数,延迟纳秒数)”语句,可延迟执行函数若干秒和纳秒;3、使用“time_sleep_until(time()+7)”语句。

php除以100保留两位小数的方法:1、利用“/”运算符进行除法运算,语法“数值 / 100”;2、使用“number_format(除法结果, 2)”或“sprintf("%.2f",除法结果)”语句进行四舍五入的处理值,并保留两位小数。

判断方法:1、使用“strtotime("年-月-日")”语句将给定的年月日转换为时间戳格式;2、用“date("z",时间戳)+1”语句计算指定时间戳是一年的第几天。date()返回的天数是从0开始计算的,因此真实天数需要在此基础上加1。

php字符串有下标。在PHP中,下标不仅可以应用于数组和对象,还可应用于字符串,利用字符串的下标和中括号“[]”可以访问指定索引位置的字符,并对该字符进行读写,语法“字符串名[下标值]”;字符串的下标值(索引值)只能是整数类型,起始值为0。

方法:1、用“str_replace(" ","其他字符",$str)”语句,可将nbsp符替换为其他字符;2、用“preg_replace("/(\s|\ \;||\xc2\xa0)/","其他字符",$str)”语句。

php判断有没有小数点的方法:1、使用“strpos(数字字符串,'.')”语法,如果返回小数点在字符串中第一次出现的位置,则有小数点;2、使用“strrpos(数字字符串,'.')”语句,如果返回小数点在字符串中最后一次出现的位置,则有。

在php中,可以使用substr()函数来读取字符串后几个字符,只需要将该函数的第二个参数设置为负值,第三个参数省略即可;语法为“substr(字符串,-n)”,表示读取从字符串结尾处向前数第n个字符开始,直到字符串结尾的全部字符。
