PHP mySQL查詢刪除雙數組

Question

在下面的示例中，我將ID的數組僅用於將其變成一段時間，然後返回到數組中，僅用於使頁面上的逗號發生爆炸。當然，必須有一個更簡單的方法來做到這一點。

我是$行[ 'ID']組成的數組後

function get_other_elector_phone($telephone,$current,$criteria){ 
    $the_others = mysql_query("SELECT * FROM electors WHERE telephone = '$telephone' $criteria"); $results = ''; 
    while($row = mysql_fetch_array($the_others)) { 
    $results .= $row['ID'].','; } return $results; 
} 


$others = get_other_elector_phone(g('electors',$elector,'telephone'),$elector,$criteria); 
        if($others){ $others = explode(',',$others); 

Answer 1

，而不是

function get_other_elector_phone($telephone,$current,$criteria){ 
    $the_others = mysql_query("SELECT * FROM electors WHERE telephone = '$telephone' $criteria"); $results = ''; 
    while($row = mysql_fetch_array($the_others)) { 
    $results .= $row['ID'].','; } return $results; 
    } 
} 

只是返回的mysql_fetch_array()

function get_other_elector_phone($telephone,$current,$criteria){ 
    $the_others = mysql_query("SELECT * FROM electors WHERE telephone = '$telephone' $criteria"); $results = ''; 
    return mysql_fetch_array($the_others); 
} 

的結果則有不需要爆炸函數的輸出。

Answer 2

就像@daverandom說，剛重建陣列，這是語法：

function get_other_elector_phone($telephone,$current,$criteria){ 
    $the_others=mysql_query("SELECT * FROM electors WHERE telephone = '$telephone' $criteria"); 
    $results = array(); 
    $i=0; 
    while($row = mysql_fetch_array($the_others)) { 
    $results [$i]= $row['ID']; 
    $i++; 
    } 
    //results returned outside loop 
    return $results; 
} 

$others = get_other_elector_phone(g('electors',$elector,'telephone'),$elector,$criteria); 

的$其他人將返回一個數組。
