[]运算符不支持字符串

对于此代码我得到error.at此行$sname[] = $rs['StudentId']; PHP致命错误：[]运算符不支持字符串 $ sname = array（）; $ i = 0;[]运算符不支持字符串

foreach($data as $rs){ 

    foreach($SchoolName as $sname){ 
//  echo $rs['SchoolName'].'=='.$sname."<br />"; 
     echo $i."<br />";     
     if($rs['SchoolName'] == $sname){ 
      $sname[] = $rs['StudentId']; 
     } 
     $i++; 
    }     
}

[]运算符不支持字符串...请如何解决这个 – Allov 2011-05-05 11:05:46

我假设$ rs是一个字符串，而不是一个数组。例如，用var_dump检查$ rs的数据。 – superbly 2011-05-05 11:06:21

WORKING DEMO

$SchoolNames = Array(10003, "Southwestern College", "National University", "Western Governors University", "Southwestern College Admissions Center - Evaluations Dept"); 
$data = array(
    0 => Array(
     'STU_MANG_fname' => "Jennifer", 
     'STU_MANG_lname' => "patel", 
     'SchoolName' => "Southwestern College Admissions Center - Evaluations Dept", 
     'ShipAddress1' => "900 Otay Lakes Road", 
     'ShipState' => "CALIFORNIA" 
    ) 
); 


foreach($data as $studen_info){ 
    foreach($SchoolNames as $id=>$school_name){ 
     if($studen_info['SchoolName'] == $school_name){ 
      $student_names[$school_name] = $id; 
      //$student_names[$school_name] = $student_info['StudentId'];; 
     } 
    } 
} 

print_r($student_names);

有学生信息数组中，你不给我“StudentId”，所以我想你想使用的学生阵列的关键，如果有，其实是“StudentId “使用我行注释掉

$ rs是一个数组，$ rs ['SchoolName'] =>“学校名称” – Allov 2011-05-05 11:16:55

我在说的是试图在字符串上添加一个数组项目 – mcgrailm 2011-05-05 11:17:11

我想这个数组......存储学生与学校名称阵列 ID（ [西南大学] => 10002,2003,20225 [大学] => 10282,90281 [西部州长大学] => 156 ） – Allov 2011-05-05 11:17:32

在接下来的循环中，

foreach ($SchoolName as $sname) {

你是屁股将$SchoolName的每个元素都指向$sname。然后在此行上：

$sname[] = $rs['StudentId'];

您试图将$sname作为数组对待。我怀疑你有一个重复的变量名称。

我声明：$ sname = array（）; – Allov 2011-05-05 11:30:06

，然后在内部循环中覆盖它。 ;） – 2011-05-05 11:33:30

我想这个数组...... ......存储学校编号与学校名称Array（[Southwestern College] => 10002,2003,20225 [National University] => 10282,90281 [Western Governors University] => 156 ） – Allov 2011-05-05 11:34:35

这应该工作 - 但你必须有StudentId指数呈现$ RS阵列，太...

$data = array(
    array("SchoolName" => "Roy", "StudentId" => "1000,1001,1002"), 
    array("SchoolName" => "MIT", "StudentId" => "2000,2001,2002"), 
    array("SchoolName" => "Southwestern College", "StudentId" => "3000,3001,3002"), 
    array("SchoolName" => "National University", "StudentId" => "4000,4001,4002"), 
    array("SchoolName" => "Western Governors University", "StudentId" => "5000,5001,5002"), 
); 

$return = array(); 

foreach($data as $rs){ 
    $return[$rs['SchoolName']] = $rs['StudentId']; 
} 

print_r($return);

我不undersantd你来自哪里去那个阵列？ – mcgrailm 2011-05-05 12:06:14

我自己写过吗？ – shadyyx 2011-05-05 12:07:41

$sname = array(); 
      $k=0; 
      for($i=0;$i<count($data);$i++) 
      { 
       $id_str ='';    
       for($j=0;$j<count($SchoolName);$j++) 
       {     
        if($data[$i]['SchoolName'] == $SchoolName[$j]){ 
         $id_str .= intval($data[$i]['StudentId']).","; 
        } 
        $sname[$SchoolName[$j]] = $id_str; 
       }    
      }
