[英]converting php code to html
我一直很难尝试将我的php代码转换为html已有5个小时了,在这一点上,我真的很疲惫:X。 这是我的PHP代码
<?php
$con=mysqli_connect("localhost","dbuser","pw","dbname");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT * FROM tablea");
echo "<table border='1' >
<tr>
<th>id</th>
<th>Subject_Code</th>
<th>date</th>
<th>name</th>
<th>description</th>
<th>Other_Details</th>
</tr>";
while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['id'] . "</td>";
echo "<td>" . $row['Subject_Code'] . "</td>";
echo "<td>" . $row['date'] . "</td>";
echo "<td>" . $row['name'] . "</td>";
echo "<td width='600' class='table_width'>" . $row['description'] . "</td>";
echo "<td width='600' class='table_width' align='center'>" . $row['Other_Details'] . "</td>";
echo "</tr>";
}
echo "</table>";
mysqli_close($con);
?>
这是我到目前为止对HTML所做的
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>database connections</title>
</head>
<body>
<?php
$username = "dbuser";
$password = "pw";
$host = "localhost";
$database= "dbname";
$connector = mysql_connect($localhost,$dbuser,$pw,dbname)
or die("Unable to connect");
echo "Connections are made successfully::";
$selected = mysql_select_db("test_db", $connector)
or die("Unable to connect");
//execute the SQL query and return records
$result = mysql_query("SELECT * FROM tablea ");
?>
<table border="2">
<thead>
<tr>
<th>id</th>
<th>Subject_Code</th>
<th>date</th>
<th>name</th>
<th>description</th>
<td>Other_Details</td>
</tr>
</thead>
<tbody>
<?php
while ($row = mysql_fetch_array($result)) {
?>
<tr>
<td><?php echo $row['id']; ?></td>
<td><?php echo $row['Subject_Code']; ?></td>
<td><?php echo $row['date']; ?></td>
<td><?php echo $row['name']; ?></td>
<td><?php echo $row['description']; ?></td>
<td><?php echo $row['Other_Details']; ?></td>
</tr>
<?php mysql_close($connector); ?>
</body>
</html>
小帮助请在这里,谢谢!
编辑:似乎有些人不理解我的问题。 我的php工作正常,因此我想将php代码转换为html。 基本上,我希望数据库中的表使用HTML表显示。
你不关门;
因此将代码更改为:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>database connections</title>
</head>
<body>
<?php
/////////////////////////////////// change \\\
$username = "dbuser";
$password = "pw";
$host = "localhost";
$database= "dbname";
$connector = mysql_connect($localhost,$username,$password)
or die("Unable to connect");
echo "Connections are made successfully::";
$selected = mysql_select_db($database, $connector)
or die("Unable to connect");
/////////////////////////////////// end change \\\
//execute the SQL query and return records
$result = mysql_query("SELECT * FROM tablea ");
?>
<table border="2">
<thead>
<tr>
<th>id</th>
<th>Subject_Code</th>
<th>date</th>
<th>name</th>
<th>description</th>
<td>Other_Details</td>
</tr>
</thead>
<tbody>
<?php
while ($row = mysql_fetch_array($result)) :
?>
<tr>
<td><?php echo $row['id']; ?></td>
<td><?php echo $row['Subject_Code']; ?></td>
<td><?php echo $row['date']; ?></td>
<td><?php echo $row['name']; ?></td>
<td><?php echo $row['description']; ?></td>
<td><?php echo $row['Other_Details']; ?></td>
</tr>
<?php endwhile;?>
<?php mysql_close($connector); ?>
</body>
</html>
实际上,您的问题是,就像您所说的html版本一样,没有像$localhost
这样的变量,但是您传递参数来连接mysql等。错误代码下面显示了代码的变量不匹配。
错误代码 :
<?php
$username = "dbuser";
$password = "pw";
$host = "localhost";
$database= "dbname";
$connector = mysql_connect($localhost,$dbuser,$pw,dbname);
^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^
//here there is no variable like what you passing to connect mysql that's problem here
?>
解决方案:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>database connections</title>
</head>
<body>
<?php
$con=mysqli_connect("localhost","dbuser","pw","dbname");
// Check connection
if(mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT * FROM tablea");
echo "<table border='1' >
<tr>
<th>id</th>
<th>Subject_Code</th>
<th>date</th>
<th>name</th>
<th>description</th>
<th>Other_Details</th>
</tr>";
while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['id'] . "</td>";
echo "<td>" . $row['Subject_Code'] . "</td>";
echo "<td>" . $row['date'] . "</td>";
echo "<td>" . $row['name'] . "</td>";
echo "<td width='600' class='table_width'>" . $row['description'] . "</td>";
echo "<td width='600' class='table_width' align='center'>" . $row['Other_Details'] . "</td>";
echo "</tr>";
}
echo "</table>";
mysqli_close($con);
?>
</body>
</html>
这是另一个利用PDO的版本-就可维护性和多功能性而言,到目前为止是php连接器的优越者。 我在MySQL,SQLite和SQLServer下使用相同的代码-唯一更改的是连接字符串。
您会注意到我立即提取所有结果。 我还利用了我们返回数组的事实。 该数组的每个元素都是一行。 每行是一个单元格数组。 这大大减少了输出结果集所需的代码。 我们只需要两个forEach循环即可。
<?php
$host = 'localhost';
$userName = 'dbuser';
$password = 'pw';
$nameOfDb = 'dbname';
$nameOfTable = 'tablea';
$pdo = new PDO('mysql:host='.$host, $userName, $password);
$pdo->query("use " . $nameOfDb);
// desired results requested explicitly, so when we get an array for the row's data, the elements will be in the same order
// - not required if the order of the columns in the database matches the desired display order. (we could just use 'select *' then)
//$query = $pdo->prepare('select * from '.$nameOfTable);
$query = $pdo->prepare('select id, Subject_Code, date, name, description, Other_Details from '. $nameOfTable);
$query->execute();
$query->setFetchMode(PDO::FETCH_ASSOC);
$rows = $query->fetchAll();
?><!doctype html>
<html>
<head>
</head>
<body>
<table>
<thead>
<tr>
<th>id</th><th>Subject_Code</th><th>date</th><th>name</th><th>description</th><th>Other_Details</th>
</tr>
</thead>
<tbody><?php
forEach($rows as $curRow)
{
echo '<tr>';
// use this one if you want to display the columns in the same order they are returned in the query results
// AND you'd like to display all columns in the result
forEach($curRow as $curCell)
echo '<td>'.$curCell.'</td>';
// otherwise, you can request the desired elements by name
//
// echo '<td>' . $curCell['id'] . '</td>'
// echo '<td>' . $curCell['Subject_Code'] . '</td>'
echo '</tr>';
}
?></tbody>
</table>
