Write a program in PHP to connect to the database and output all records of the table

PHP writing program can connect to the database and output all the records in the table to set the data

mysql_connect('localhost','root','') or die("Connection error"); //Link database

mysql_select_db('database') or die("Fail to select database.");//Select database

$sql="select * from `mytable`";

$result=mysql_query($sql);

echo '

';

while($row=mysql_fetch_array($result))

{

echo '

';

foreach($row as $rw){

echo "

";

}

echo '

';

}

echo '

".$rw."
';

?>

How does native php output the last executed sql of mysql

method one:

$link = mysql_connect("192.168.1.1", "myuser", "mypass"); --Connect to the database

if(FALSE == $link)

{

echo "Connect database failed!";

}

$query =

"select * from a order by id";

mysql_select_db('test', $link);--Select database

$result = mysql_query($query);--Execute query statement

if(FALSE == $result)

{

echo "Querry failed!";

}

$i = 0;

$j = 0;

while($i {

$meta_c=0;

if($meta_c=mysql_fetch_row($result))--Get the result set of each row

{

while($j {

echo $meta_c[$j;

}

echo "

";

} // while;

$j=0;

}

mysql_free_result($result);--Release the result set

mysql_close($link);--Close the connection

?>

Method Two:

$link = mysql_connect("192.168.1.1", "myuser", "mypass"); --Connect to the database

if(FALSE == $link)

{

echo "Connect database failed!

";

}

mysql_select_db('test', $link);--Select database

$result = mysql_query("select * from a order by id");--Execute the query statement

if(FALSE == $result)

{

echo "Querry failed!";

}

while($row = mysql_fetch_array($result, MYSQL_NUM))--Get the value in the array, because the result set is stored in a two-dimensional array

{

foreach ($row as $col_value)--take values ​​one by one

{

echo " $col_value ";

}

}

mysql_free_result($result);--Release the result set

mysql_close($link);)--Close the connection

?>
