uniq多維數組

Question

我需要將兩個數組合併到一個數組中。

看起來像array_merge不支持多維數組。

課程

Array ( 
[0] => Array ([Name] => Course1 [CourseId] => 1 [Selected] =>) 
[1] => Array ([Name] => Course2 [CourseId] => 2 [Selected] =>) 
[2] => Array ([Name] => Course3 [CourseId] => 3 [Selected] =>) 
[3] => Array ([Name] => Course4 [CourseId] => 4 [Selected] =>) 
[4] => Array ([Name] => Course5 [CourseId] => 5 [Selected] =>) 
) 

TeacherCourses

Array ( 
[0] => Array ([CourseId] => 1 [Selected] => selected) 
[1] => Array ([CourseId] => 2 [Selected] => selected) 
[2] => Array ([CourseId] => 3 [Selected] => selected) 
) 

我需要這個結果

Array ( 
[0] => Array ([Name] => Course1 [CourseId] => 1 [Selected] => selected) 
[1] => Array ([Name] => Course2 [CourseId] => 2 [Selected] => selected) 
[2] => Array ([Name] => Course3 [CourseId] => 3 [Selected] => selected) 
[3] => Array ([Name] => Course4 [CourseId] => 4 [Selected] =>) 
[4] => Array ([Name] => Course5 [CourseId] => 5 [Selected] =>) 
) 

Answer 1

您是否嘗試過foreach loop？

在這裏，我們去,:

foreach($arr1 as $key => $value){ 
    foreach($arr2 as $value2){ 
     if($value['CourseId'] === $value2['CourseId']){ 
      $arr1[$key]['Selected'] = $value2['Selected']; 
     }    
    } 
} 

希望這會幫助你。
