在表格中插入数据时出错

Question

我有一个代码，可以在特定数据库的每个表中插入数据。运行后出现此错误

"Parse error: syntax error, unexpected '}', expecting ';' in C:\xampp\htdocs\Thesis\database\insertdata.php on line 37"

我检查了代码中的拼写错误，但我仍然没有看到任何错误，可能是循环错误引起的

这是我的代码

$db_name = array('morning_section_masterfile','evening_section_masterfile','afternoon_section_masterfile');
for($y=0;$y<=2;$y++)
{
   $db = mysql_select_db($db_name[$y],$connectDatabase);
   $tables = array('Pilot_Sections','Black_Sections');
     for($a=0;$a<=1;$a++)
     {
       //variable making
        $teacher = array ('Jane','Jeff','Liezeth','Loremas','Canada');
       $Default_Lname = 'Lorems';
       $Default_Fname = 'Vierzehn';
       $x=0;
       //Adding 30 students in one section
    do
    {
        for($i=0;$i<=30;$i++)
        {
            $section_teacher = $teacher[$x];
            $student_section = 'IT70'.$x.'E-C';
            $student_Lname = str_shuffle($Default_Lname);
            $student_Fname = str_shuffle($Default_Fname);
            $table = $tables[$a];
            $insert = "INSERT INTO $table (section_Teacher, student_Lastname, student_Firstname, student_Section) VALUES 
            ('{$section_teacher}','{$student_Lname}','{$student_Fname}','{$student_section}')";
            $insertdata = mysql_query($insert,$connectDatabase);
        }
    //check the number of students in a section section and adding another section
        if($i==31)
        {
            $x++;
            $i=0;
        }
    } while($x<=4)
  }
}

Answer 1

我这个mysql老了，你可以改成mysqli

你可以用这个：

<?php
//******  MySql Connect
$mysqli = new mysqli("localhost", "user", "password", "database");
if ($mysqli->connect_errno) {
    echo "Connect failed";

    // if connection error script stop working
    exit();
    die();
}

//****** real_escape_string (Security)
$city = $mysqli->real_escape_string($city);

//****** RESULT
$query = "SQL";
if ($result = $mysqli->query($query)) {
    while ($row = $result->fetch_assoc()) {
       echo $row["Name"];
    }
    $result->free();
}

//****** Query
$mysqli->query("SQL");

//****** Close
$mysqli->close();

?>

while 后你漏掉了一个分号

do
    {
        for($i=0;$i<=30;$i++)
        {
            $section_teacher = $teacher[$x];
            $student_section = 'IT70'.$x.'E-C';
            $student_Lname = str_shuffle($Default_Lname);
            $student_Fname = str_shuffle($Default_Fname);
            $table = $tables[$a];
            $insert = "INSERT INTO $table (section_Teacher, student_Lastname, student_Firstname, student_Section) VALUES 
            ('{$section_teacher}','{$student_Lname}','{$student_Fname}','{$student_section}')";
            $insertdata = mysql_query($insert,$connectDatabase);
        }
    //check the number of students in a section section and adding another section
        if($i==31)
        {
            $x++;
            $i=0;
        }
    } while($x<=4);

另外建议不要使用mysql_*，因为它们已被弃用，而是使用PDO 来防止sql 注入。请参考to my answer here我已经详细解释了那里。

Answer 3

试试这个，你在 while 循环末尾缺少分号。

<?php
$db_name = array('morning_section_masterfile','evening_section_masterfile','afternoon_section_masterfile');
for($y=0;$y<=2;$y++)
{
   $db = mysql_select_db($db_name[$y],$connectDatabase);
   $tables = array('Pilot_Sections','Black_Sections');
     for($a=0;$a<=1;$a++)
     {
       //variable making
        $teacher = array ('Jane','Jeff','Liezeth','Loremas','Canada');
       $Default_Lname = 'Lorems';
       $Default_Fname = 'Vierzehn';
       $x=0;
       //Adding 30 students in one section
    do
    {
        for($i=0;$i<=30;$i++)
        {
            $section_teacher = $teacher[$x];
            $student_section = 'IT70'.$x.'E-C';
            $student_Lname = str_shuffle($Default_Lname);
            $student_Fname = str_shuffle($Default_Fname);
            $table = $tables[$a];
            $insert = "INSERT INTO $table (section_Teacher, student_Lastname, student_Firstname, student_Section) VALUES
            ('{$section_teacher}','{$student_Lname}','{$student_Fname}','{$student_section}')";
            $insertdata = mysql_query($insert,$connectDatabase);
        }
    //check the number of students in a section section and adding another section
        if($i==31)
        {
            $x++;
            $i=0;
        }
    } while($x<=4);
  }
}
