如何向数组添加元素？

Question

如何将元素添加到存在的数组？我有阵列：

Array ( [0] => Array ( [user_id] => 1 [user_login] => Saibamen [user_password] => 4028a0e356acc947fcd2bfshfh3w26gdshhbf00cef11e128d484a [user_email] => teeeest@test.pl [user_active] => 1 [user_last_login_ip] => 127.0.0.1 [user_perms] => ) )

我想在此数组中添加'avatar'参数：

$avatar = md5($array_in_this_question[0]['user_email'])

Answer 1

您以与读取值时相同的方式添加值：使用其键

$array_in_this_question[0]['avatar'] = md5($array_in_this_question[0]['user_email']);

Answer 2

简单地制作

$array[0]['avatar'] = $avatar

Answer 3

你需要将数组分配给一个变量作为开始，所以：

$theArray = Array ( [0] => Array ( [user_id] => 1 [user_login] => Saibamen [user_password] => 4028a0e356acc947fcd2bfshfh3w26gdshhbf00cef11e128d484a [user_email] => teeeest@test.pl [user_active] => 1 [user_last_login_ip] => 127.0.0.1 [user_perms] => ) );
$theArray[0]['avatar'] = md5($array_in_this_question[0]['user_email']);

是你想要的我猜
