PHP date of birth checker
<p>I am currently using the following PHP code to check date of birth, the code uses the american mm/dd/yyyy although I'm trying to change it to the british dd/mm/yyyy.</p>

<p>I was hoping someone could tell me what to change:</p>

<pre><code>function dateDiff($dformat, $endDate, $beginDate)
{
    $date_parts1=explode($dformat, $beginDate);
    $date_parts2=explode($dformat, $endDate);
    $start_date=gregoriantojd($date_parts1[0], $date_parts1[1], $date_parts1[2]);
    $end_date=gregoriantojd($date_parts2[0], $date_parts2[1], $date_parts2[2]);
    return $end_date - $start_date;
}

//Enter date of birth below in MM/DD/YYYY
$dob="04/15/1993";
echo round(dateDiff("/", date("m/d/Y", time()), $dob)/365, 0) . " years.";
</code></pre>
