我有 2 個陣列，我想獲得總投票數。陣列 1 是用戶提案，陣列 2 是用戶對提案的投票。我正在嘗試比較 2 并計算每個提案的總票數。
這是 2 個陣列 -
$props = json_decode('[{"proposal":"proposal 1", "owner":"tom", "lock_time":1639440607},{"proposal":"proposal 2", "owner":"bob", "lock_time":1639455554}]', true);
$votes = json_decode('[{"vote":"approve", "owner":"tom", "prop-id":1639440607},{"vote":"reject", "owner":"bob", "prop-id":1639455554},{"vote":"reject", "owner":"tom", "prop-id":1639440607}]', true);
所需的輸出如下 -
Proposal 1 = 1 Approve and 1 Reject
Proposal 2 = 0 Approve and 1 Reject
我得到的輸出是 -
Proposal 1 = 1 Approve and 1 Reject
Proposal 2 = 1 Approve and 1 Reject
這是我沒有給出所需輸出的嘗試 -
foreach($props as $props){
$lock_time = $props['lock_time'];
$my_proposal = $props['proposal'];
foreach($votes as $votes){
$id = $votes['prop-id'];
$vote = $votes['vote'];
if($lock_time == $id){
if($vote == 'approve'){
$yay ;
}elseif($vote == 'reject'){
$nay ;
}
}
}
echo 'Proposal: '.$my_proposal.'<br>';
echo 'yay:: '.$yay.'<br>';
echo 'nay:: '.$nay.'<br>';
echo '<br><br>';
}

uj5u.com熱心網友回復：
在這個街區
if($vote == 'approve'){ $yay ; }elseif($vote == 'reject'){ $nay ;}
您需要重置每個提案的值，因此可能應該是這樣的：
foreach($props as $props){
$lock_time = $props['lock_time'];
$my_proposal = $props['proposal'];
$yay=0;
$nay=0;
foreach($votes as $vote){
$id = $vote['prop-id'];
$theVote = $vote['vote'];
if($lock_time == $id){
if($theVote == 'approve'){
$yay ;
}elseif($theVote == 'reject'){
$nay ;
}
}
}
echo 'Proposal: '.$my_proposal.PHP_EOL;
echo 'yay:: '.$yay.PHP_EOL;
echo 'nay:: '.$nay.PHP_EOL;
echo PHP_EOL;
}
