[英]Create array from values in an array
This is highly similar to a previous question ( Create an array from multidimensional array ), yet in this case I do not have a multidimensional array. 这与先前的问题( 从多维数组创建数组 )高度相似,但是在这种情况下,我没有多维数组。 Here is what I have: 这是我所拥有的:
Array
(
[0] => ratings Object
(
[id] => 1
[rating] => 4.4
)
[1] => ratings Object
(
[id] => 1
[rating] => 5.0
)
[2] => ratings Object
(
[id] => 1
[rating] => 5.0
)
)
What I'm attempting to do is create a new array that consists of only the "rating" values... 我正在尝试做的是创建一个仅包含“评级”值的新数组...
$result_array = array(0 => "4.4",
1 => "5.0",
2 => "5.0");
The following solution was unsuccessful since $value is an object rather than an array... 由于$ value是对象而不是数组,因此以下解决方案未成功...
$result_array = array();
foreach ($array as $value) {
$result_array[] = $value[1];
}
What's the correct way to go about it? 正确的解决方法是什么?
$result_array[] = $value[1];
With the above line, you're trying to use $value
as an array when it's not. 在上面的代码行中,您试图在不使用$value
时将其用作数组。 It's an object, so treat it as such. 这是一个对象,因此应将其视为。
The properties of an object can be accessed using arrow notation ( ->
). 可以使用箭头符号( ->
)访问对象的属性。 The updated code would read: 更新后的代码将显示为:
foreach ($array as $value) {
$result_array[] = $value->rating;
}
