$array_one = ['one','two','three']; $array_two = ['one'=>'one,one','two'=>'two,two','three'=>'three,three'];
$array_one
中元素的位置是已知的,比如'two'的位置是2。
但是在$array_two
中'two,two'的位置还是2吗?
很明显不是的,我如果要调换位置1和3的元素,该如何?
<code>$array_two = ['three'=>'three,three','two'=>'two,two','one'=>'one,one'];</code>
回复内容:
$array_one = ['one','two','three']; $array_two = ['one'=>'one,one','two'=>'two,two','three'=>'three,three'];
$array_one
中元素的位置是已知的,比如'two'的位置是2。
但是在$array_two
中'two,two'的位置还是2吗?
很明显不是的,我如果要调换位置1和3的元素,该如何?
<code>$array_two = ['three'=>'three,three','two'=>'two,two','one'=>'one,one'];</code>
位置?
应该是下标,而且two的下标应该是1
array_two的关联数组就用key访问!
如果只是三个元素的话 $array_two = array_reverse($array_two); 就行了
三个元素参考: @炑木 的就行了
也可以考虑 array_slice 然后将数组 加起来 (+)

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.
