MYSQL入门之二_PHP操作MYSQL
1. 本地连接MySQL www.2cto.com
$con= mysql_connect("localhost", "root", "xxxxxx");
if(!$con) {
die(&＃39;Could not connect: &＃39; .mysql_error());
}else {
echo"Connect success
\n";
}
2. SAE连接MySQL
$con =mysql_connect(SAE_MYSQL_HOST_M.&＃39;:&＃39;.SAE_MYSQL_PORT,
SAE_MYSQL_USER,SAE_MYSQL_PASS);
if (!$con) {
die(&＃39;Could not connect: &＃39; .mysql_error());
} else {
echo"Connect success
\n";
}
mysql_select_db(SAE_MYSQL_DB,$con);
3. 断开MySQL
mysql_close($con);
$sql = "CREATE DATABASE IFNOT EXISTS $DATABASE_NAME";
if(
mysql_query($sql, $con)) {
echo "Database create success
\n";
}else {
echo"Error creating database: " . mysql_error() ."
\n";
}
5. 连接使用数据库
mysql_select_db($DATABASE_NAME,$con);
6. 建立数据表
$sql ="CREATE TABLE $TABLE_NAME (
namevarchar(80),
ageint
)ENGINE=MyISAM DEFAULT CHARSET=utf8";
if(mysql_query($sql,$con)) {
echo "Table create success
\n";
}else {
echo"Error creating table: " . mysql_error() . "
\n";
}
7. 查找数据
$sql= "SELECT * FROM $TABLE_NAME where name like \"%$INPUT%\"";
$result= mysql_query($sql,$con);
while($row =mysql_fetch_array($result)) {
echo$row[&＃39;name&＃39;] . " " . $row[&＃39;age&＃39;];
echo"
";
}
8. 设置字符集（设置之后的sql操作基于utf8字符集）
mysql_query("SET NAMES &＃39;utf8&＃39;");
mysql_query("SET CHARACTER_SET_CLIENT=utf8");
mysql_query("SET CHARACTER_SET_RESULTS=utf8");
