排序基於php數組的對象

我是相當新的編程，並試圖從用戶名從mssql查詢排序此數組。已經嘗試過使用其他人在網絡上做出的一些排序功能，但沒有運氣任何幫助都會令人驚歎！排序基於php數組的對象

function getSalesPersonTargetTracker() 
{ 
$targetTracker = new StdClass(); 
$targetTracker->agents = array(); 

$server = 'blah'; 
$connectioninfo = array('database' => 'blah', 'uid' => 'blah', 'pwd' => 'blah'); 

$connection = sqlsrv_connect($server, $connectioninfo); 

$query = "{call salespersontargettracker (?)}"; 
$params = array(
       date_format(new DateTime(), '01/M/Y') 
      ); 

//Run the Query    
$statement = sqlsrv_query($connection, $query, $params); 

if (sqlsrv_fetch($statement) === false) 
    print_r(sqlsrv_errors(), true); 

//Read in the overall numbers 
$targetTracker->target = (float)sqlsrv_get_field($statement, 0); 
$targetTracker->workingDays = (int)sqlsrv_get_field($statement, 1); 
$targetTracker->currentDay = (int)sqlsrv_get_field($statement, 2); 
$targetTracker->dailyTarget = (float)sqlsrv_get_field($statement, 3); 
$targetTracker->pointsShouldBeOn = (float)sqlsrv_get_field($statement, 4); 
$targetTracker->pointsOn = (float)sqlsrv_get_field($statement, 5); 
$targetTracker->pointsDifference = (float)sqlsrv_get_field($statement, 6); 
$targetTracker->moneyShouldBeOn = (float)sqlsrv_get_field($statement, 7); 
$targetTracker->moneyOn = (float)sqlsrv_get_field($statement, 8); 
$targetTracker->moneyDifference = (float)sqlsrv_get_field($statement, 9); 

//Move to the next result 
sqlsrv_next_result($statement); 

//Run through all of the agents and show their details 
while (sqlsrv_fetch($statement)) 
{ 
    $salesPerson = new StdClass(); 
    $salesPerson->team = sqlsrv_get_field($statement, 0); 
    $salesPerson->username = sqlsrv_get_field($statement, 1); 
    $salesPerson->target = (float)sqlsrv_get_field($statement, 2); 
    $salesPerson->workingDays = (int)sqlsrv_get_field($statement, 3); 
    $salesPerson->currentDay = (int)sqlsrv_get_field($statement, 4);

    $salesPerson->pointsShouldBeOn = (float)sqlsrv_get_field($statement, 6); 
    $salesPerson->pointsOn = (float)sqlsrv_get_field($statement, 7);

    $salesPerson->moneyShouldBeOn = (float)sqlsrv_get_field($statement, 9); 
    $salesPerson->moneyOn = (float)sqlsrv_get_field($statement, 10); 
    $salesPerson->moneyDifference = (float)sqlsrv_get_field($statement, 11); 

    //Add this person to the people list 
    $targetTracker->agents[] = $salesPerson; 
} 

return $targetTracker; 
} 
$targetTrackerall = getSalesPersonTargetTracker(); 

?> 
    <table width="100%">

    foreach ($targetTrackerall->agents as $agent) {

     if ($agent->pointsDifference < 0)

在您的數據庫查詢的ORDER BY條款...！ – deceze

你會得到什麼？你想要什麼？哪些代碼與您的問題相關？ – PiTheNumber

無法添加到數據庫查詢的訂單，就像用於其他事情一樣！將是最簡單的方法： - > –

如果用戶名域是唯一的，那麼你可以使用它作爲代理陣列的關鍵和陣列上使用ksort。

<?php 
... 

while (sqlsrv_fetch($statement)) 
{ 
    ... 

    //Add this person to the people list 
    $targetTracker->agents[$salesPerson->username] = $salesPerson; 
    ksort($targetTracker->agents); 
} 
... 

?>

這很好用，謝謝。只需要找出如何讓它忽略大小寫！ –

@AdamClark可以使用'$ targetTracker->代理[strtolower（$ salesPerson-> username）] = $ salesPerson;'。如果你的PHP版本高於5.4.0，你也可以使用'ksort（$ targetTracker-> agents，SORT_STRING | SORT_FLAG_CASE）;' – air4x

您應該使用usort，寫一個回調函數像

} 
    function cmp($a, $b) 
    { 
     return strcmp($a->username, $b->username); 
    } 
    usort($targetTracker, 'cmp'); 

    return $targetTracker; 
}

我該如何整合函數轉換成上面的代碼，我很無用！ –

你可以在返回數組之前把它放到你的函數中，聲明排序函數然後調用usort –

試過這個但是我沒有運氣\t return $ targetTracker; } 函數cmp（$ a，$ b） { return strcmp（$ a-> username，$ b-> username）; } $ targetTrackerall = getSalesPersonTargetTracker（）; $ targetTrackerallt = cmp（$ targetTrackerall） –
