PHP find value in multidimensional / nested array

I've trawled the site and the net and have tried various recursive functions etc to no avail, so I'm hoping someone here can point out where I'm going wrong :)

I have an array named $meetingArray with the following values;

Array ( 
    [0] => Array ( 
        [Meet_ID] => 9313 
        [Meet_Name] => 456136 
        [Meet_CallInNumber] => 
        [Meet_AttendeeCode] => 
        [Meet_Password] => 
        [Meet_ScheduledDateTime] => 2011-07-18 16:00:00 
        [Meet_ModeratorCode] => 
        [Meet_RequireRegistration] => 0 
        [Meet_CurrentUsers] => 0 
    ) 
    [1] => Array ( 
        [Meet_ID] => 9314 
        [Meet_Name] => 456120 
        [Meet_CallInNumber] => 
        [Meet_AttendeeCode] => 
        [Meet_Password] => 
        [Meet_ScheduledDateTime] => 2011-07-18 16:00:00 
        [Meet_ModeratorCode] => 
        [Meet_RequireRegistration] => 0 
        [Meet_CurrentUsers] => 0 
    ) 
)

I also have a variable named $meetID.

I want to know if the value in $meetID appears in [Meet_Name] within the array and simply evaluate this true or false.

Any help very much appreciated before I shoot myself :)

Write a method something like this:

function valInArr($array, $field, $value) {
 foreach ($array as $id => $nestedArray) {
  if (strpos($value,$nestedArray[$field])) return $id;
  //if ($nestedArray[$field] === $value) return $id; // use this line if you want the values to be identical
 }
 return false;
}

$meetID = 1234;
$x = valInArr($array, "Meet_Name", $meetID);
if ($x) print_r($array[$x]);

This function will evaluate true if the record is found in the array and also enable you to quickly access the specific nested array matching that ID.

For single-dimensional arrays you can use array_search(). This can be adapted for multi-dimensional arrays like so:

function array_search_recursive($needle, $haystack, $strict=false, $stack=array()) {
    $results = array();
    foreach($haystack as $key=>$value) {
        if(($strict && $needle === $value) || (!$strict && $needle == $value)) {
            $results[] = array_merge($stack, array($key));
        }

        if(is_array($value) && count($value) != 0) {
            $results = array_merge($results, array_search_recursive($needle, $value, $strict, array_merge($stack, array($key))));
        }
    }
    return($results);
}

function multi_in_array($needle, $haystack, $key) {
    foreach ($haystack as $h) {
        if (array_key_exists($key, $h) && $h[$key]==$needle) {
            return true;
        }
    }
    return false;
}

if (multi_in_array($meetID, $meetingArray, 'Meet_Name')) {
    //...
}

I am unsure what you mean by

$meetID appears in [Meet_Name]

but simply substitute the $h[$key]==$needle condition with something that meets your needs.
