under ideal circumstances:

$string = "aaaaaaaa=bbbbbbbbb";
$array = explode("=", $string);
$count = strlen($array[0])+1;

echo $count;

edit: strpos() is a much, much, better approach...

$str = "aaaaaaaa=bbbbbbbbb"; 
echo strpos($str, '=')+1;

Output:

Unless it is absolutely certain that '=' is in the string, the return value of strpos() should be checked.

E.g.:

echo ($loc = strpos($str, '=')) !== FALSE ? $loc + 1 : 'not found!';

Is "=" the 14th or 16th character?

if($string[13]=='=' || $string[15]=='=')
{
  echo "yes";
} else {
  echo "no";
}

Remembering that character positions are counted starting from 0.

That would need a check with strlen() or isset as well, otherwise the string might be accessed out of bounds (but at least that is not so bad in PHP).
