如何检索 php 中表的布尔值？

Question

<?php
include 'config.php';

$sql1="SELECT Project_id FROM assigned_project_tester  where Tester_name IN (SELECT Username FROM user_master where Username='meet.patel')";
$result=$conn->query($sql1);


while($row=$result->fetch_assoc())
{  echo $proid[]=$row['Project_id'];            //this is getting printed from table project_master table   
    echo '<br>';

} 
$i='';
for ($i=0; $i<sizeOf($proid); $i++)
{
    echo 'here are agian project names';
    echo $proid[$i];                          //this checkpoint to check array  and for loop is working or not
    echo '<br>';
   $sql2="select Test_creation,Test_execution from assigned_project_tester where Project_id =' " . $proid[$i] . "'   ";
  $result1=$conn->query($sql2);
 while($row1=$result1->fetch_assoc())      //I think it is not getting inside while loop
  { echo 'inside if ';                     //this is not getting printed .............
     echo $row1['Test_creation'];          //test_creation is boolean value and data type is tinyint in table assigned_project_tester
     echo $row1['Test_execution'];         //test_execution is boolean value and data type is tiny integer in table assigned_project_master
                                           //what i want to do is print yes if user has test_creation permission else no
  }                                        //same for test_execution I knew that value stored in database is 1 and 0 but
                                           //why it is not getting printed        
}

我想从名为 assigned_project_tester 的 table 中检索 Test_creation 和 Test_execution 的值，如果值为 1 则打印 yes 否则打印 no.I 有在代码中为您完成注释，请检查它。好吧，我正在尝试解决这个问题，因为 29 hours.All 正在打印其他内容，例如 project_id，而这只是行不通，请帮助我。提前致谢

我对你的一些问题感到困惑。似乎您不需要两个单独的查询。只有这个行得通吗？

SELECT Project_id, 
       Test_creation, 
       Test_execution 
FROM   assigned_project_tester 
WHERE  Tester_name = 'meet.patel'

这应该会列出 "meet.patel" 分配的所有项目及其状态。

然后您可以使用 while 语句循环遍历结果。

$result = $mysqli->query($query);

while ($row = $result->fetch_assoc()) {
    echo $row["Project_id"];
    echo $row["Test_creation"];
    echo $row["Test_execution "];
}

$result->free();
