too long

I have an array like this:

Array
(
    [47] => Array
        (
            [name1] => 
        )

    [43] => Array
        (
            [name2] => 
        )

    [53] => Array
        (
            [name3] => selected
        )

    [50] => Array
        (
            [name4] => 
        )

    [51] => Array
        (
            [name5] => 
        )

    [37] => Array
        (
            [name6] => 
        )

)

and I want to show the value of name1, name2, name3, name4, name5, name6. I tried with:

for($i = 0; $i < 6; $i++){
    echo $array_object[$i] . "<br/>";
}

but it doesn't work. How can I fix it? Thanks!

    You can use the array_keys function to get the indexes and then use them numerically:

    $keys=array_keys($array_object);
    for($i = 0; $i < 6; $i++){
        echo $array_object[$keys[$i]][{'name'.($i+1)}]."<br/>";
    }
    

    This will allow you to use index [0] even though it refers to index [47] based on your example data in the question.

    While I haven't bothered to check if your data will always contain at least 6 entries (again based on the example code you posted) but if your loop exceeds the number of entries in your array you will get an undefined index error unless you check it first.
