I'm looking for a way to calculate the age of a person, given their DOB in the format dd/mm/yyyy.
I was using the following function which worked fine for several months until some kind of glitch caused the while loop to never end and grind the entire site to a halt. Since there are almost 100,000 DOBs going through this function several times a day, it's hard to pin down what was causing this.
Does anyone have a more reliable way of calculating the age?
//replace / with - so strtotime works
$dob = strtotime(str_replace("/","-",$birthdayDate));
$tdate = time();
$age = 0;
while( $tdate > $dob = strtotime('+1 year', $dob))
EDIT: this function seems to work OK some of the time, but returns "40" for a DOB of 14/09/1986
return floor((time() - strtotime($birthdayDate))/31556926);
