One if statement halting progress - php

Question

I am having trouble with some if statements. To cut a long story short, when a certain statement is true, the code stops and doesn't move on to the next loop/series of if statements.
Here is the first statement that once reached, doesn't move on.
else if ((($pteam_score[$i] == $popposition_score[$i]) && ($pteam_score[$i] != 0) && ($popposition_score[$i] != 0))) {
$team_points[$i]-=2;
$opposition_points[$i]-=2;
$team_win[$i]-=0;
$team_draw[$i]-=1;
$team_loss[$i]-=0;
$team_extra[$i]-=0;
$opp_win[$i]-=0;
$opp_draw[$i]-=1;
$opp_loss[$i]-=0;
$opp_extra[$i]-=0;
$played[$i]-=1;
echo "hey";
$query9=$database->query("UPDATE results_a SET team_name='$team[$i]', team_score='$pteam_score[$i]',
opposition_score='$popposition_score[$i]', opposition_name='$opposition[$i]' where fixture_id='$fixture_id'");
}
And here is the second. Bare in mind there are about 20 of these ifs/else ifs/ and when any of the others are hit, the points are decucted (as they are with the two bad loops also) butit seems it doesn't then move on to a separate section of the code. Perhaps coincidentally, both bad loops involve a draw result!
else if ((($pteam_score[$i] == $popposition_score[$i]) && ($pteam_score[$i] != 0) && ($popposition_score[$i] != 0))) {
$team_points[$i]-=2;
$opposition_points[$i]-=2;
$team_win[$i]-=0;
$team_draw[$i]-=1;
$team_loss[$i]-=0;
$team_extra[$i]-=0;
$opp_win[$i]-=0;
$opp_draw[$i]-=1;
$opp_loss[$i]-=0;
$opp_extra[$i]-=0;
$played[$i]-=1;
echo "what?";
$query9=$database->query("UPDATE results_a SET team_name='$team[$i]', team_score='$pteam_score[$i]',
opposition_score='$popposition_score[$i]', opposition_name='$opposition[$i]' where fixture_id='$fixture_id'");
}
Can anybody see any reason the code would stop dead with the above two statements? The echo stuff is just to see which option is hit. As I said, these two loops are hit at the correct times, but they are the only two that seem to stop the process.
EDIT - A SECTION THAT WORKS FINE
if (($team_score[$i] == $pteam_score[$i]) && ($opposition_score[$i] == $popposition_score[$i])) {
$team_points[$i]+=0;
$opposition_points[$i]+=0;
$team_win[$i]+=0;
$team_draw[$i]+=0;
$team_loss[$i]+=0;
$team_extra[$i]+=0;
$opp_win[$i]+=0;
$opp_draw[$i]+=0;
$opp_loss[$i]+=0;
$opp_extra[$i]+=0;
$played[$i]+=0;
echo "0";
$query11=$database->query("UPDATE results_a SET team_name='$team[$i]', team_score='$pteam_score[$i]',
opposition_score='$popposition_score[$i]', opposition_name='$opposition[$i]' where fixture_id='$fixture_id'");
}
else if (($pteam_score[$i] == 0) && ($popposition_score[$i] == 0)) {
$team_points[$i]+=0;
$opposition_points[$i]+=0;
$team_win[$i]+=0;
$team_draw[$i]+=0;
$team_loss[$i]+=0;
$team_extra[$i]+=0;
$opp_win[$i]+=0;
$opp_draw[$i]+=0;
$opp_loss[$i]+=0;
$opp_extra[$i]+=0;
$played[$i]+=0;
echo "bla";
}
if (($pteam_score[$i] != $team_score[$i]) && ($popposition_score[$i] == $opposition_score[$i])) {
if (($pteam_score[$i] > $popposition_score[$i]) && ($pteam_bonus[$i] > $popposition_score[$i])) {
$team_points[$i]-=3;
$opposition_points[$i]-=0;
$team_win[$i]-=1;
$team_draw[$i]-=0;
$team_loss[$i]-=0;
$team_extra[$i]-=0;
$opp_win[$i]-=0;
$opp_draw[$i]-=0;
$opp_loss[$i]-=1;
$opp_extra[$i]-=0;
$played[$i]-=1;
echo "6";
$query5=$database->query("UPDATE results_a SET team_name='$team[$i]', team_score='$pteam_score[$i]',
opposition_score='$popposition_score[$i]', opposition_name='$opposition[$i]' where fixture_id='$fixture_id'");
}
Thanks in advance
