例如
<div ng-repeat = 'list in lists'>
<?php
$user_post_id = "{{list.user.id}}"; //this syntax works
var_dump($user_post_id); // gives String(16) '1'
$user_post_int_id = (int)$user_post_id; // change from string to int
var_dump($user_post_int_id); // gives int(1) 0, I don't know why isn't type conversion working!
echo $user_post_id; // echoes out 1
echo $user_post_int_id; //echoes out the 0
所以我认为主要问题是类型转换，因为我尝试了另一件事，其中String(1)转换为int(1)没有问题，但String(16)一切都分开了，结果为0。
我有3个建议4u(在我的服务器上所有工作正常)
作为原文加上我的评论:
<div ng-repeat = 'list in lists'>
<?php
$user_post_id = "{{list.user.id}}"; //this syntax works
var_dump($user_post_id); // gives String(16) '1'
$user_post_int_id = (int)$user_post_id; // change to int
var_dump($user_post_int_id);
// gives int(1) 1, is not test your php/server conf!
echo $user_post_id; // echoes out 1
echo $user_post_int_id; //echoes out 1
那么我建议你试着修改你的代码，在你的服务器上运行:
替换 $ user_post_id ="{{list.user.id}}"; user_post_id美元= (int) {{list.user.id}}; //希望你的php不会显示错误
替换 user_post_int_id = (int) user_post_id美元; user_post_int_id美元=地板((int) user_post_id美元);或 $ user_post_int_id =装天花板((int) user_post_id美元);
替换 $ user_post_id ="{{list.user.id}}"; user_post_id美元= (int) + 1 ({{list.user.id}}); 或者加零，这些技巧有时对我有用!
注。(int)可以骗你，PHP可以不让你使用十六进制bin或SMTH else。重新测试两次!php.net/manual/en/language.types.integer.phpphp.net/manual/en/language.types.type-juggling.php
你不能在服务器端语句中使用Angular表达式，因为Angular语句在运行完所有服务器端逻辑后才运行在客户端。
在你的代码中:
<div ng-repeat = 'list in lists'>
<?php
$user_post_id = "{{list.user.id}}" //list.user.id is a JS variable, you cannot use it in PHP.
$user_post_int_id = (int)$user_post_id; // something wrong here, you do not need this step, normally if you retrieved the code from server side.
{{ $user_post_int_id }} //this should not work
But still this blade function fails
@if(Auth::user()->id == $user_post_int_id)
do something //returns false, makes alot of sense, as again you are trying to get variables from JS and passing them to PHP scripts. This will never work.
@endif
