very simple convertion asp 2 php

[RS_Arm]

Hello.
I need to use this code in asp to work in php.
I just can't figure it out alone.
Can anybody help me, please?

posicaoHead = InStr(1, linha, "Te")
linha = Right(linha, Len(linha) - posicaoHead - 1)

Thank you.

$posicaoHead = strpos($linha, 'Te');
$linha = substr($linha, -(strlen($linha) - $posicaoHead - 1));
