PHP mySQL查询删除双数组

Question

在下面的示例中，我将ID的数组仅用于将其变成一段时间，然后返回到数组中，仅用于使页面上的逗号发生爆炸。当然，必须有一个更简单的方法来做到这一点。

我是$行[ 'ID']组成的数组后

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); 
} 

的结果则有不需要爆炸函数的输出。

Answer 2

就像@daverandom说，刚重建阵列，这是语法：

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$其他人将返回一个数组。
