我正在尝试使用内联样式在 echo 中应用背景颜色，但它没有应用背景颜色，而是仅更改文本颜色。我想更改代码特定部分的背景颜色
echo "<p style='color:orange';background-color:red;>"."record number: ".$rec_num. "</p>"."<br>"
程序代码是
class db_access
{
private $_uname;
private $_pass;
private $_db;
private $_server;
//_construct connects databaseand fetchest he result
public function __construct($server,$user_name,$password,$d_b)
{
$this->_server=$server;
$this->_pass=$password;
$this->_uname=$user_name;
$this->_db=$d_b;
$con=mysql_connect($this->_server,$this->_uname,$this->_pass);
$db_found=mysql_select_db($this->_db,$con);
if($db_found)
{
$sql="SELECT * FROM login";
$result = mysql_query($sql);
if ($result)
{
while ( $db_field = mysql_fetch_assoc($result) )
{
static $rec_num=1;
//inline css
echo "<p style='color:orange';background-color:red;>"."record number: ".$rec_num. "</p>"."<br>";
print $db_field['ID'] . "<BR>";
print $db_field['u_name'] . "<BR>";
print $db_field['pass'] . "<BR>";
print $db_field['email'] . "<BR><br><br>";
$rec_num++;
}
//returns the connection name that is used as a resource id in __destruct function
return $this->_con=$con;
}
else {die(mysql_error());}
}
else
{return die(mysql_error());}
}
// destruct function closes database
public function __destruct()
{
$close=mysql_close($this->_con);
if($close)
{print "connection closed";}
else {die(mysql_error());}
}
}
$db=new db_access("127.0.0.1","root","","fabeeno");
//var_dump($db);
