从数组IF中取消设置元素

Question

I get some data from the database, which is saved in "$Data". $Data looks like this:

        [Data] => Array
            (
                [0] => Array
                    (
                        [PrinterID] => 3
                        [PrinterName] => PRT03_EDV
                        [isDefaultPrinter] => 1
                        [isMapped] => 0
                    )

                [1] => Array
                    (
                        [PrinterID] => 1
                        [PrinterName] => PRT01_Zentral
                        [isDefaultPrinter] => 0
                        [isMapped] => 1
                    )

                [2] => Array
                    (
                        [PrinterID] => 2
                        [PrinterName] => PRT02_BH
                        [isDefaultPrinter] => 0
                        [isMapped] => 0
                    )

I need to verify, that there is no array in $Data, where "isDefaultPrinter == True" and "isMapped == False". Programatically:

if ( $Data["isDefaultPrinter"] == true and $Data["isMapped"] == false ) {
  // Remove from Array
}

I did start to code this on my own based on this and my result was a terrible looking nested loop, which did not work :-(
I am a beginner and I wanted to ask, if there is an nice and easy way to do this?

Thank you

Here's a version using array_filter, which is sort of built for this. See http://php.net/manual/en/function.array-filter.php

$valid = array_filter($Data, function($var) {
    return !($var['isDefaultPrinter'] && !$var['isMapped']);
});
