當數組中值爲0它變成 -

-1

Array 
(
    [played] => 2 
    [random] => 0 
    [win] => 2 
    [draws] => 11 
    [passes] => 2 
    [swaps] => 6 
    [hpoints] => 0 
    [lpoints] => -12 
    [hmoves] => 11 
    [lmoves] => 0 
    [hpasses] => 1 
    [lpasses] => 0 
    [hswaps] => 3 
    [lswaps] => 0 
    [today] => 2013-04-04 
    [tdpoints_temp] => -24 
    [tdpoints] => -24 
    [htdpoints] => 0 
    [ltdpoints] => -12 
)

我再拿到陣列伸到單獨的值是這樣的：

foreach($userStats as $singleStat){ 
    $played = $singleStat['played']; 
    $random = $singleStat['random']; 
    $win = $singleStat['win']; 
    $draws = $singleStat['draws']; 
    $passes = $singleStat['passes']; 
    $swaps = $singleStat['swaps']; 
    $hpoints = $singleStat['hpoints']; 
    $lpoints = $singleStat['lpoints']; 
    $hmoves = $singleStat['hmoves']; 
    $lmoves = $singleStat['lmoves']; 
    $hpasses = $singleStat['hpasses']; 
    $lpasses = $singleStat['lpasses']; 
    $hswaps = $singleStat['hswaps']; 
    $lswaps = $singleStat['lswaps']; 
    $today = $singleStat['today']; 
    $tdpoints_temp = $singleStat['tdpoints_temp']-$playeridPoints; 
    $tdpoints = $singleStat['tdpoints']-$playeridPoints; 
    $htdpoints = $singleStat['htdpoints']; 
    $ltdpoints = $singleStat['ltdpoints']; 
}

沒問題除。所有變量（$ random，$ hpoints，$ lmoves，$ lpasses，$ lswaps和$ htdpoints）都是「0」，當我回應它們時，會顯示爲「 - 」我不知道爲什麼，我想讓他們按照他們的要求返回「0」。

任何幫助表示讚賞，並提前:-)

感謝

下面是完整的代碼：

if($cacheAvailable == true){ // WE GOT A CACHE 
    //$memcache->delete('stats_'.$opponent); 
    $userStats = $memcache->get('stats_'.$opponent); 

    echo '<pre>'; 
    print_r($userStats); 
    echo '</pre>'; 

    foreach($userStats as $singleStat){ 
     $played = $singleStat['played']; 
     $random = $singleStat['random']; 
     $win = $singleStat['win']; 
     $draws = $singleStat['draws']; 
     $passes = $singleStat['passes']; 
     $swaps = $singleStat['swaps']; 
     $hpoints = $singleStat['hpoints']; 
     $lpoints = $singleStat['lpoints']; 
     $hmoves = $singleStat['hmoves']; 
     $lmoves = $singleStat['lmoves']; 
     $hpasses = $singleStat['hpasses']; 
     $lpasses = $singleStat['lpasses']; 
     $hswaps = $singleStat['hswaps']; 
     $lswaps = (int)$singleStat['lswaps']; 
     $today = $singleStat['today']; 
     $tdpoints_temp = $singleStat['tdpoints_temp']-$playeridPoints; 
     $tdpoints = $singleStat['tdpoints']-$playeridPoints; 
     $htdpoints = $singleStat['htdpoints']; 
     $ltdpoints = $singleStat['ltdpoints']; 
    } 
    echo 'This swap: '.$lswaps.'<br><br>'; 
}

必須有一些代碼是這樣做的。它不能自動完成。你能告訴我們你到底在哪裏迴應它嗎？ – Rikesh 2013-04-04 12:35:59

我想這不是全部的foreach，你還在裏面做了什麼？ – Shoe 2013-04-04 12:36:07

我認爲邪惡的代碼嚮導騙你... – andreapier 2013-04-04 12:37:42

0 cantbe轉換爲 ' - ' 必須有由您

嘗試使用類型轉換

01有些轉換
