Conditional search on multidimensional array

[waubain]

I am trying to use a multidimensional array for the first time, but having trouble getting the conditional search for "//Find next meeting date" section.

Any help would be appreciated. Thank you.

         //today's date variable
        date_default_timezone_set("America/Chicago");    
        $todaysdate = date("Ymd");        //Date format as YYYYMMDD

        //create multidimentional array
        $meetinfo = Array
        (
          array('meetdate' => "20190110", 'speaker' => "Bob", 'room' => "Classroom #1", 'ce' => 1.0),  
          array('meetdate' => "20180512", 'speaker' => "Joe", 'room' => "Classroom #3", 'ce' => 1.0), 
          array('meetdate' => "20180820", 'speaker' => "Sally", 'room' => "Classroom #6", 'ce' => 1.0),  
          );

        // Sort the multidimensional array
        usort($meetinfo, "custom_sort");
        // Define the custom sort function
        function custom_sort($a,$b) {
          return $a['meetdate']>$b['meetdate'];
        }

        //find next meeting date
       for ($index = 0; $index < count($meetinfo); $index++){
            if ($todaysdate <= $meetinfo["meetdate"][$index]) {                                                          
                $nextmeetdate = $meetdate["meetdate"][$index]; 
                $nextmeetdate = date("l F d, Y", strtotime($nextmeetdate)); //format date
                $speaker = $meetdate["speaker"];
                $room = $meetdate["room"];
                $ce = $meetdate["ce"];
                break;  //exit loop
            } else {
                    $nextmeetdate = "TBA";
                    $speaker = "TBA";
                    $room = "TBA";
                    $ce = "TBA";
                    }
        }  

        //show data 
        echo "<p><strong>" .$nextmeetdate. "</strong>"; echo "<br />";
        echo "Speaker: " .$speaker. ""; echo "<br>";
        echo "Topic: " .$topic. ""; echo "<br />";
        echo "Location: " .$location. "";echo "<br />";
        echo "CPE CE: " .$ce. "contact hour"; echo "<br />";
        echo "</p>";

I found a solution that will work.

        $buffer = array();
        foreach ($meetinfo as $element) {
            if ($todaysdate <= ($element['meetdate'])) {               
                $buffer[] = $element;
                $nextmeetdate = $buffer[0]['meetdate']; 
                $nextmeetdate = date("l F d, Y", strtotime($nextmeetdate)); //format date
                $speaker = $buffer[0]["speaker"];
                $room = $buffer[0]["room"];
                $ce = $buffer[0]["ce"];
                break;  //exit loop
                } 
                    else {
                        $nextmeetdate = "TBA";
                        $speaker = "TBA";
                        $room = "TBA";
                        $ce = "TBA";
                    }
          }
