php search data in array

Question

Need your help in finding the problem .the program will look for data in the array and display the name if there is a match ,the program does not work correctly ,locking for data only in the first array.

<?php
$result = '';
$birthdays = array(
    array("Alex",5,12),
    array("Tom",2,20),
    array("Sarah",6,12),
    array("Anna",6,8),
    array("Jonh",10,7)
);
if(isset($_POST)){
    $d = isset($_POST['day_bd']) ? $_POST['day_bd'] : '';
    $m = isset($_POST['month_bd']) ? $_POST['month_bd'] : '';

    $result = getBirthdayNameByDate($birthdays, $d, $m);

    $result = $result ? $result : 'no results found';
}
 function getBirthdayNameByDate($birthdaysArray, $day, $month){
    foreach($birthdaysArray as $array){
        if($array[1] == $month && $array[2] == $day){
            return $array[0];
        }
        return null;
    }
}
?>
<!DOCTYPE HTML>

    <head>
        <style type="text/css">

        <?php if($result){ ?>
        <div class="nameOut">
            <?php

Move down your return null; one step.

function getBirthdayNameByDate($birthdaysArray, $day, $month){
    foreach($birthdaysArray as $array){
        if($array[1] == $month && $array[2] == $day){
            return $array[0];
        }     
    }
    return null;
}

But please note that your program only will return the first match. Consider storing the results in an array, so no birthday ppl are left out!

@AlexanderBazikalo cool! edited my answer a bit, I really think you should use an array instead. feel free to mark as 'accepted' if it solved your problem: meta.stackexchange.com/questions/5234/…
