special char + eregi()

[adamluc]

Ive searched, and ive seen many tutorials but i must not be getting it. Ive tried using brackets, ive tried using escape chars but nothing is working. Perhaps im just using them in wrong order, but right now ive got everything twisted. How do i determine or find the '+' inside a string for example "2+2="?

else if(eregi( '+' , $q ))
{
$a = sscanf($q, "%d+%d=", $num1, $num2);
$answer = ($num1 + $num2);
$response = $answer;
}

thanks for any help given

You can use the split() function, as follows:
[PHP]
$exp="2 + 2";
list($num1, $num2) = split('[+]', $exp);
$answer = $num1+$num2;
echo "answer = $answer<br />";[/PHP]
