Convert an associative array to a simple array of its values in php
提问by ItsGeorge
I would like to convert the array:
我想转换数组:
Array (
[category] => category
[post_tag] => post_tag
[nav_menu] => nav_menu
[link_category] => link_category
[post_format] => post_format
)
to
到
array(category, post_tag, nav_menu, link_category, post_format)
I tried
我试过
$myarray = 'array('. implode(', ',get_taxonomies('','names')) .')';
which echos out:
呼应:
array(category, post_tag, nav_menu, link_category, post_format)
So I can do
所以我可以做
echo $myarray;
echo 'array(category, post_tag, nav_menu, link_category, post_format)';
and it prints the exact same thing.
它打印出完全相同的东西。
...but I can't use $myarrayin a function in place of the manually entered array because the function doesn't see it as array or something.
...但我不能$myarray在函数中使用来代替手动输入的数组,因为该函数不会将其视为数组或其他东西。
What am I missing here?
我在这里缺少什么?

You should use the array_values()function.
您应该使用该array_values()功能。

create a new array, use a foreach loop in PHP to copy all the values from associative array into a simple array
创建一个新数组,使用 PHP 中的 foreach 循环将关联数组中的所有值复制到一个简单数组中
$data=Array(); //associative array
$simple_array = array(); //simple array
foreach($data as $d)
{
$simple_array[]=$d['value_name'];
}
