大家好,我在用CodeIgniter PHP foreach 过一个email地址的表单,发现一些不符合正则表达式要求的Email,列出来以便改进。
难题在于难以将结果以object形式列出来。
代码:
PHP:
<code> $this->db->where('status', 'subscribed'); $email_preliminary=$this->db->select('email')->get('user'); $email_raw = array(); foreach ($email_preliminary->result() as $row): $email_to_test=$row->email; if(filter_var($email_to_test, FILTER_VALIDATE_EMAIL)||preg_match('/\d*[1-9]\d*/', $email_to_test)) { $email_raw[] = $email_to_test; } else{ } endforeach; $record_raw=array_unique($email_raw); $data['record'] = json_decode (json_encode ($record_raw), FALSE); $this->load->view('login&signup/signup_test_view', $data); } </code>
HTML Signup_test_view里,我有:
<code> <?php foreach ($record->result() as $row): ?> <span><?php echo $row->email; ?></span><br> <?php endforeach; ?> </code>
错误信息为:
Call to a member function result() on a non-object in D:\views\login&signup\signup_test_view.php
但我不是已经用下面这行代码把array转变成object了吗:
<code> $data['record'] = json_decode (json_encode ($record_raw), FALSE); </code>
谢谢!
更新:
有同学建议把view里的代码改成
<code> <?php foreach ($record as $row): ?> <span><?php echo $row->email; ?></span><br> <?php endforeach; ?> </code>
也试了,错误信息仍为:
A PHP Error was encountered
Severity: Notice
Message: Trying to get property of non-object
Filename: login&signup/signup_test_get_wrong_email_view.php

array不也是蛮好用的么,那你需要一个把array转换成object ?
$obj = (object) $array;

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
