PHP:if语句在foreach中不起作用
我有两个数组。其中一个包含json格式的对象，每个对象有2个变量，就像数组（3）{[“John”]=>string（2）“20”[“Mary”]=>string（2）“18”[“Paul”]=>string（2）“23”}。这显示了人们的姓名和年龄。这些年龄将在浏览器的表单中输入，并使用GET请求发送到服务器。另一个数组包含姓名相同但年龄不同的人的对象。每个对象都是从一个类创建的，包含它们的名称和作业。此阵列的创建方式如下：PHP:if语句在foreach中不起作用,php,arrays,foreach,Php,Arrays,Foreach,我有两个数组。其中一个包含json格式的对象，每个对象有2个变量，就像数组（3）{[“John”]=>string（2）“20”[“Mary”]=>string（2）“18”[“Paul”]=>string（2）“23”}。这显示了人们的姓名和年龄。这些年龄将在浏览器的表单中输入，并使用GET请求发送到服务器。另一个数组包含姓名相同但年龄不同的人的对象。每个对象都是从一个类创建的，包含它们的名称和作业。此阵列的创建方式如下： <?php class Person{
