使用PHP操作数据库有两种方式
下面演示使用第一种方式：
<!doctype html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<?php
$conn = mysql_connect("localhost", "root", "zxbbugu");
if(!$conn) {
die("Could not connect:" . mysql_error());
}
mysql_select_db("test", $conn);
//mysql_query("SET NAMES utf8");
$result = mysql_query("INSERT INTO mytable(headline, create_time) VALUES(‘中国‘, ‘" . date("Y-m-d h:i:s") . "‘);");
if( $result < 1) {
echo "insert error!";
}
$query = mysql_query("SELECT * FROM mytable LIMIT 100 OFFSET 0;");
while ($row = mysql_fetch_array($query, MYSQL_BOTH)) {
echo "<p>", $row["id"], " - " , $row["headline"], " - ", $row["create_time"], "</p>";
}
mysql_close();
?>
</body>
</html>
下面是使用PDO方式：
<!doctype html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
</head>
<body>
<?php
$pdo = new PDO("mysql:host=localhost;dbname=test", "root", "zxbbugu");
$stmt = $pdo->prepare(‘SELECT * FROM mytable WHERE id = :id‘);
$stmt->execute(array(":id"=>1));
foreach ($stmt as $row) {
echo $row["headline"];
}
$result = $pdo->exec("INSERT INTO mytable(headline, create_time) VALUES(‘中国‘, ‘" . date("Y-m-d h:i:s") . "‘);");
if($result) {
$str = sprintf("add data completed, lastupdateid=%s", $pdo->lastInsertId());
echo $str;
}
$rs = $pdo->query("SELECT * FROM mytable");
while ($row = $rs->fetch()) {
echo "<p>", $row["id"], " - " , $row["headline"], " - ", $row["create_time"], "</p>";
}
?>
</body>
</html>
建议使用PDO方式，这样可以减少SQL注入安全性问题。（php5以上建议使用PDO方式做数据库操作）
