如何从多维数组中提取特定的关键数据

Question

I'm converting XML file into associative array to pull out the data, the problem is that I have to make 10 loops depends on arrays number in order to get the data.

is there a better way to get a specific column data without creating many loops? because I want to assign them to variables.

the array I'm trying to get data from

Array
(
    [catalog] => Array
        (
            [comp] => Array
                (

I'm trying to get the data like this!

I have 2 arrays "customer" and "customer1"

I want to get the data like this

customer=>author

the output

jack
jon

because they are in the customer array

its it possible to do that ??

Answer 1

Say your array is stored in $arr you would access the comp index and then loop it since those are numeric indexes. Then you have an array to whittle down some more. This all seems a bit bloated by the array structure but will work

$arr; //Set this to your converted xml
$comps = $arr['catalog']['comp'];

foreach($comps as $comp){
    echo $comp['look']['shp']['wok']['group']['customer']['author'];
}
