Question, how to get the $myarray in single value like:

问题是，如何以单个值获取$myarray，如:

echo $myarray['email'];  will show email@domain.com

7 个解决方案

#1

Look at the keys and indentation in your print_r:

查看print_r中的键和缩进:

echo $myarray[0]['email'];

echo $myarray[0]['gender'];

...etc

等

#2

Use array_shift function

使用array_shift函数

$myarray = array_shift($myarray);

This will move array elements one level up and you can access any array element without using [0] key

这将把数组元素提升到一个级别，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@domain.com

将显示email@domain.com

#3

I think you want this:

我想你想要的是:

foreach ($myarray as $key => $value) {
    echo "$key = $value\n";
}

#4

The first element of $myarray is the array of values you want. So, right now,

$myarray的第一个元素是您想要的值的数组。所以,现在,

echo $myarray[0]['email']; // This outputs 'email@domain.com'

If you want that array to become $myarray, then you just have to do

如果你想让这个数组变成my$数组，那么你只需要这么做

$myarray = $myarray[0];

Now, $myarray['email'] etc. will output as expected.

现在，$myarray['email']等将按预期输出。

#5

You can also use array_column(). It's available from PHP 5.5: php.net/manual/en/function.array-column.php

还可以使用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.

它从数组的单个列返回值，由column_key标识。可选地，您可以提供一个index_key，通过输入数组中的index_key列中的值来索引返回数组中的值。

print_r(array_column($myarray, 'email'));

#6

foreach ($newarray as $key => $val) {
    echo "$key = $val\n";
}

#7

echo $myarray[0]->['email'];

Try this only if it you are passing the stdclass object

只有在传递stdclass对象时才尝试此操作
