Question

I have following array construction: $array[$certain_key][some_text_value]

And in a while loop, I want to print the data from the array, where $certain_key is a specific value.

I know how to loop through multidimensional arrays, which is not the complete solution to this problem:

foreach ($a as $v1) {
    foreach ($v1 as $v2) {
        echo "$v2\n";
    }
}

I do not want to loop the whole array each time, but only when $certain_key is matched.

EDIT: to be more exact, this is what I’m trying to do:

$array[$array_key][some_text];

while reading from db {

  //print array where a value returned from the db = $array_key

}

Answer 1

foreach ($array as $certain_key => $value) {
    if($certain_key == $row['db_id']) {
        foreach ($value as $some_text_value) {
            echo "$v2\n";
        }
    }
}
