如何从多维数组中获取字符串变量中的数组值使用Php？

Question

I have an multidimensional array and want to get all values with comma without loop in a string variable.

Is it possible ?

Array :

Array
(
    [0] => stdClass Object
        (
            [id] => 61
        )

    [1] => stdClass Object
        (
            [id] => 62
        )
)

I want to get like this : 61,62 .

How to do this ?

Answer 1

Just do a loop over array and make new array to get values, Then convert new array to comma separated string.

foreach($arr as $v){
 $newarr[] = $v->id;
}
// Convert new array to comma separated string
$str = implode(',', $newarr);

or

use array_map()

function getid($v) {
    return $v->id;
}
$str = implode(array_map("getid", $arr), ',');
echo $str;
