Actually i didn’t get what you want but i think this might work
$yourString = "engineering";
$vowels = array("a", "e", "i", "o", "u", "A", "E", "I", "O", "U");
$occured = 0;
$output = "";
for($i=0;$i<strlen($yourString);$i++)
{
if(in_array($yourString[$i],$vowels) && ++$occured > 2) break;
$output .= $yourString[$i];
}
print $output;
