Look at the keys and indentation in your print_r:
查看您的 中的键和缩进print_r：
echo $myarray[0]['email'];
echo $myarray[0]['gender'];
...etc
...等等

Use array_shiftfunction
使用array_shift功能
$myarray = array_shift($myarray);
This will move array elements one level up and you can access any array element without using [0]key
这会将数组元素向上移动一级，您可以在不使用[0]键的情况下访问任何数组元素
echo $myarray['email'];
will show [email protected]

You can also use array_column(). It's available from PHP 5.5: php.net/manual/en/function.array-column.php
您也可以使用array_column(). 它可以从 PHP 5.5 获得：php.net/manual/en/function.array-column.php
It returns the values from a single column of the array, identified by the column_key. Optionally, you may provide an index_key to index the values in the returned array by the values from the index_key column in the input array.
它从数组的单个列中返回值，由 column_key 标识。或者，您可以提供一个 index_key 以通过输入数组中 index_key 列中的值对返回数组中的值进行索引。
print_r(array_column($myarray, 'email'));

echo $myarray[0]->['email'];
Try this only if it you are passing the stdclass object
仅当您通过时才尝试此操作 stdclass object

The first element of $myarrayis the array of values you want. So, right now,
的第一个元素$myarray是您想要的值数组。所以，现在，
echo $myarray[0]['email']; // This outputs '[email protected]'
If you want that array to become $myarray, then you just have to do
如果您希望该数组成为$myarray，那么您只需要做
$myarray = $myarray[0];
Now, $myarray['email']etc. will output as expected.
现在，$myarray['email']等将按预期输出。
