Question

我收到此错误：

注意：数组php中的未定义偏移量

有谁知道我的错误在哪里？

//$forme count of my array 
for( $counter = 0; $counter < $forme; $counter++ )  {

    if($az[$counter] > 0)
    {
        $test=$connect->fetch_all("select * from `tbl_jobs_numbers` where `sub_id`='".$Subid[$counter]."' && `job_id`='".$JobID."' && `city_id`='".$ostan."' limit '".$az [ $counter ]."' , '".$ta[ $counter ]."'") ;

        foreach($test as $puriya)
        {
            print $mobiles=$puriya['number']."<br/>";
        }
    }
    else
    {
        $test=$connect->fetch_all("select * from `tbl_jobs_numbers` where `sub_id`='".$Subid[$counter]."' && `job_id`='".$JobID."' && `city_id`='".$ostan."' ") ;

        foreach($test as $puriya)
        {
            //print $mobiles=$puriya['number']."<br/>";
        }
    }
}

如果要迭代数组的每个项目，更简单的方法是使用foreach（基于不是：

// array_values to make sure that the keys are numeric
foreach (array_values($az) as $index => $item) {
    if ($item > 0) {
        $test=$connect->fetch_all("select * from `tbl_jobs_numbers` where `sub_id`='".$Subid[$index]."' && `job_id`='".$JobID."' && `city_id`='".$ostan."' limit '".$az[$index]."' , '".$ta[$index]."'") ;

        foreach($test as $puriya)
        {
            print $mobiles=$puriya['number']."<br/>";
        }
    } else {
        $test=$connect->fetch_all("select * from `tbl_jobs_numbers` where `sub_id`='".$Subid[$index]."' && `job_id`='".$JobID."' && `city_id`='".$ostan."' ") ;

        foreach($test as $puriya)
        {
            //print $mobiles=$puriya['number']."<br/>";
        }
    }
}

这应避免$az的未定义索引错误。
