MYSQL入门之二_PHP操作MYSQL

1. 本地连接MySQL

$con= mysql_connect(“localhost”, “root”, “xxxxxx”);

if(!$con) {

die(&＃039;Could not connect: &＃039; .mysql_error());

}else {

echo”Connect success
/n”;

}

2. SAE连接MySQL

$con =mysql_connect(SAE_MYSQL_HOST_M.&＃039;:&＃039;.SAE_MYSQL_PORT,

SAE_MYSQL_USER,SAE_MYSQL_PASS);

if (!$con) {

die(&＃039;Could not connect: &＃039; .mysql_error());

} else {

echo”Connect success
/n”;

}

mysql_select_db(SAE_MYSQL_DB,$con);

3. 断开MySQL

mysql_close($con);

4. 建立数据库

$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 cr本文来源gao@[email protected]*eating 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[&＃039;name&＃039;] . ” ” . $row[&＃039;age&＃039;];

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 &＃039;utf8&＃039;”);

mysql_query(“SET CHARACTER_SET_CLIENT=utf8”);

mysql_query(“SET CHARACTER_SET_RESULTS=utf8”);
