问题描述
我使用以下代码从数据库表中获取数据:
<!DOCTYPE HTML>
< html>
< head>
< title>搜寻资料< / title>
< / head>
< body>
< table>
< tr>
< td align =center> EMPLOYEES DATA< / td>
< / tr>
< tr>
< td>
< table border =1>
< tr>
< td> NAME< / td>
< td> EMPLOYEES< br> NUMBER< / td>
< td> ADDRESS< / td>
< / tr>
//使用基于字段名称的序列搜索数据的示例
//search.php
mysql_connect(localhost,root, ); //数据库连接
mysql_select_db(db_psu_online);
$ order =SELECT * FROM tb_income_statement_igp_fields;
//为了搜索数据
//在定单变量中声明
$ result = mysql_query($ order); ($ data = mysql_fetch_row($ result)){
echo //(
// //命令执行结果被保存为
//在$ result
$ b变量中) < TR>< TD> $数据[1]; / TD>< TD> $数据[0]< / TD>< TD> $数据[2]< / TD>< / TR>中);
}
?>
< / table>
< / td>
< / tr>
< / table>
< / body>
< / html>
以上代码的输出是这样的:
不知道为什么字符:<$ c $
解决方案
您是否正在保存文件扩展名为 .php
?是否在您的服务器上安装并启用了PHP?
至少有一个这些是否,因为你所看到的是HTML中的原始PHP输出 - 如果你使用浏览器的View Source,你会清楚地看到它。
I am using the following code to fetch data from a database table:
<!DOCTYPE HTML>
<html>
<head>
<title>Search data</title>
</head>
<body>
<table>
<tr>
<td align="center">EMPLOYEES DATA</td>
</tr>
<tr>
<td>
<table border="1">
<tr>
<td>NAME</td>
<td>EMPLOYEES<br>NUMBER</td>
<td>ADDRESS</td>
</tr>
<?php
//the example of searching data with the sequence based on the field name
//search.php
mysql_connect("localhost","root","");//database connection
mysql_select_db("db_psu_online");
$order = "SELECT * FROM tb_income_statement_igp_fields";
//order to search data
//declare in the order variable
$result = mysql_query($order);
//order executes the result is saved
//in the variable of $result
while($data = mysql_fetch_row($result)){
echo("<tr><td>$data[1]</td><td>$data[0]</td><td>$data[2]</td></tr>");
}
?>
</table>
</td>
</tr>
</table>
</body>
</html>
The output of the code above is this:
I don't know why the characters: "); } ?>
are being printed.
解决方案
Are you saving the file with the extension .php
? Is PHP installed and enabled on your server?
The answer to at least one of these is "no", because what you are seeing is the raw PHP output in the HTML - if you use the browser's View Source, you'd see that clearly.
