使用 AngularJS 数据绑定，我想以用户类型num2的形式返回num1 * num2;num1是一个PHP变量(用户无法更改(。接下来，如何将PHP变量传递给角度js？，我尝试了：
<!doctype html>
<html>
<head>
<title>AngularJS App</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.5.6/angular.min.js"></script>
</head>
<body>
<? php $num1 = 5;?>
<div ng-app="myApp" ng-controller="myCtrl">
<form action="/action_page.php">
<div id="num1">
Num1: <div ng-model="num1" ng-init="num1('<?php echo $num1?>')">
</div>
Num2: <div id="num2" ng-model="num2">
<input type="number">
</div>
Multiplied: {{num1 * num2}}
<input type="submit" value="Submit">
</div>
</form>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.num1 ;
$scope.num2 ;
});
</script>
</body>
</html>
如何num1将 PHP 变量传递给 AngularJS 应用程序，假设预设的 PHP 变量num1=5？
将ng-init="num1('<?php echo $num1?>')">更改为ng-init="num1 = '<?php echo $num1; ?>' ">
