我无法使用 php 代码显示我的 mysql 表。它显示的只是列名,而不是与它们关联的值。我知道我的用户名密码和数据库都是正确的,但就像我说的表格没有显示我添加的值。任何帮助将不胜感激这是我的mysql代码:
CREATE TABLE Guitars
(
Brand varchar(20) NOT NULL,
Model varchar(20) NOT NULL,
PRIMARY KEY(Brand)
);
insert into Guitars values('Ibanez','RG');
insert into Guitars values('Ibanez','S');
insert into Guitars values('Gibson','Les Paul');
insert into Guitars values('Gibson','Explorer');
这是我的 php 代码:
<?php
$db_host = '*****';
$db_user = '*****';
$db_pwd = '*****';
$database = '*****';
$table = 'Guitars';
if (!mysql_connect($db_host, $db_user, $db_pwd))
die("Can't connect to database");
if (!mysql_select_db($database))
die("Can't select database");
// sending query
$result = mysql_query("SELECT * FROM {$table}");
if (!$result) {
die("Query to show fields from table failed");
}
$fields_num = mysql_num_fields($result);
echo "<table border='1'><tr>";
// printing table headers
for($i=0; $i<$fields_num; $i++)
{
$field = mysql_fetch_field($result);
echo "<td>{$field->name}</td>";
}
echo "</tr>\n";
// printing table rows
while($row = mysql_fetch_row($result))
{
echo "<tr>";
// $row is array... foreach( .. ) puts every element
// of $row to $cell variable
foreach($row as $cell)
echo "<td>$cell</td>";
echo "</tr>\n";
}
mysql_free_result($result);
?>
