Question

<?php
$get_user="SELECT privillage FROM admin_user WHERE id='".$_SESSION['user_id']."'";
 // echo $get_user;
 $exe_query=mysql_query($get_user);
$row=mysql_fetch_array($exe_query);
 $privillage_data = unserialize($row['privillage']); 
                  //print_r($privillage_data);
                  //$privillage_data1=explode(",",$privillage_data);
 echo '<pre>';
print_r($privillage_data);
$count=count($privillage_data);
 //echo "Count".$count;

 if($privillage_data[0] == '1' || $privillage_data[1] == '1' || $privillage_data[2] == '1' && $count >=1)
    {
        $priv_add ="true";
        echo "add--".$priv_add."</br>";
    }
else{$priv_add ="false";}

if($count >=2 && $privillage_data[1] == '2' || $privillage_data[0] == '2' || $privillage_data[2] == '2')
    {
        $priv_edit ="true";
        echo "edit--".$priv_edit."</br>";
    }
    else{$priv_edit ="false";}

    if($count ==3 && $privillage_data[2] == '3' || $privillage_data[0] == '3' || $privillage_data[1] == '3')
     {
        $priv_delete ="true";
        echo "delete--".$priv_delete."</br>";
    }
    else{$priv_delete ="false";}

当使用上面的代码时，我在 if 条件下得到未定义的偏移误差!! 如何解决胶印问题!! 需要帮助!!请让我简单

Answer 1

看起来你有数组索引的空值

尝试使用isset()或empty()

isset($privillage_data[0])或!empty($privillage_data[0])

等等...对于所有索引

所以你的病情将是

if((!empty($privillage_data[0]) && $privillage_data[0] == '1') || (!empty($privillage_data[1]) && $privillage_data[1] == '1') || (!empty($privillage_data[2]) && $privillage_data[2] == '1') && $count >=1)

对于您正在使用的所有条件

等等

Answer 2

转储privillage_data的内容。你错过了一个阵列密钥，这是你期待的。另外，上面哪一行给出错误？
