Add two related conditions in if / PHP

I would like to find a way to add a condition in my "if" related to a first condition. Is there a way translating "FOLLOW BY" in php?

My start script with one condition:

 foreach ($array as $key => $value) {
 if ($begin == false && $value == 'T') {
 ...
 }}

My final script with two conditions related :

 foreach ($array as $key => $value) {
 if ($begin == false && $value == 'T' FOLLOW BY $value == 'D') {
 ...
 }}

Array for example : 

 Word => S
 Word => H 
 Word => T //related with D
 Word => D //related with T
 Word => Q

I don't know if my answer fit your case, but a simpler solution would be to just implode the array and perform a simple text search.

In case your $array is numeric, you can check the value of $array[$key+1]

foreach ($array as $key => $value) {
    if ($begin == false && $value == 'T' && array_key_exists($key+1, $array) && $array[$key+1] == 'D') {
        ...
    }
}

Note that I also insert in the code a check if the next key exists in your array (otherwise you will have a problem in the last loop)

If your $array is associative array it's a bit harder. We need to save the keys in a temp array so we can check their position:

$array_keys = array_keys($array);
foreach ($array as $key => $value) {
    $key_pos = array_search($key, $array_keys);
    if ($begin == false && $value == 'T' && array_key_exists($key_pos+1, $array_keys) && $array[array_keys[$key_pos+1]] == 'D') {
        ...
    }
}
