比较多个多维数组

Question

I hope the title is descriptive, I am stuck so I am going to do my best to describe the issue.

I have a comparison I need to make for bed types on a search I am building. One is a $_POST array from the search form ($array1). It lists the bed types, so for example it would look something like:

array('King', 'Queen', 'Full');

My second array ($array2) is from my CMS's profile information and looks like this:

array(
"field_bed_types" => array(                
  "und" => array(
    "0" => array(
      "value" => "King"
            )

    "1" => array(
      "value" => "Double"
            )
        )
    )
)

The more bed types they have selected in their profile (there are 6) the more entries there would be past "1" in $array2.

What I am trying to achieve it to take the search types from $array1 and see if $array2 has all of the bed types listed in referenced in $array1. If not, I am doing a continue; and moving on to the next user profile record in my foreach loop.

In this example above, given that $array2 has only King and Double and $array1 is looking for a King, Queen and Full bed, the search should come back as FALSE and then continue to the next record. My question is, how do I do this?

I hope this makes sense, please let me know if you have any further questions.

Note: Drupal is the CMS in use here, but for all purposes this is still a multidimensional array, I just mention my CMS as a way to say that I don't have a way to change the data structure.

Answer 1

Try this

foreach($array1 as $key=>$type)
{
    $return[$key]=false;
    foreach($array2['field_bed_types']['und'] as $typeArray)
    {
        if ($type==$typeArray['value'])
            $return[$key]=true;
    }
}
$failed=false;
foreach($return as $match)
{
    if($match==flase)
    {
        $failed=true;
    }
}
if($failed==false)
{
    // do stuff if passed
}
