刪除元素arrayin php

Question

如何刪除包含關鍵字的數組中的值？我試過功能unset數組，但它不起作用。

$labels=array("FullName"=>"Full name", 
         "Email"=>"Email", 
         "LoginName"=>"Login", 
         "Password"=>"Password", 
         "PasswordConfirm"=>"Confirm Your password"); 

我需要刪除PasswordConfirm及其值。

Answer 1

unset會工作得很好：

$labels=array("FullName"=>"Full name", 
         "Email"=>"Email", 
         "LoginName"=>"Login", 
         "Password"=>"Password", 
         "PasswordConfirm"=>"Confirm Your password"); 

unset ($labels['Password'], $labels['PasswordConfirm']); 
print_r($labels); 

這裏是fiddle。

Answer 2

只需設置「PasswordConfirm」鍵即可刪除PasswordConfirm及其值。

$labels=array("FullName"=>"Full name", 
        "Email"=>"Email", 
        "LoginName"=>"Login", 
        "Password"=>"Password", 
        "PasswordConfirm"=>"Confirm Your password"); 

unset ($labels['PasswordConfirm']); 
print_r($labels);
