MySQL Connection
It is very easy to connect to MySQL db, like Oracle connection.
- $link = mysql_connect(’server name’, ‘username’, ‘password’);<?php
$link = mysql_connect(’localhost’, ‘root’, ‘duygu’);
if (!$link) {
die(’Could not connect: ‘ . mysql_error());
}
echo ‘Connected successfully’;
mysql_close($link);
?> - Use mysql_select_db(”test”,$link) function to select the database which we will use.
<?php
$link = mysql_connect(’localhost’, ‘root’, ‘duygu’);
if (!$link) {
die(’Could not connect: ‘ . mysql_error());
}
echo ‘Connected successfully<br>’;
if (!mysql_select_db(”test”,$link)) {
echo “Unable to select test: ” . mysql_error();
exit;
}
mysql_close($link);
?> - We will write our sql statement and to execute this statement use mysql_query($sql); function
<?php
$link = mysql_connect(’localhost’, ‘root’, ‘duygu’);
if (!$link) {
die(’Could not connect: ‘ . mysql_error());
}
echo ‘Connected successfully<br>’;if (!mysql_select_db(”test”,$link)) {
echo “Unable to select test: ” . mysql_error();
exit;
}
$sql = “SELECT * FROM myblog”;$result = mysql_query($sql);
if (!$result) {
echo “Could not successfully run query ($sql) from DB: ” . mysql_error();
exit;
}
mysql_close($link);
?> - Control if there is a data or not. If there is a data write it on the page.
<?php
$link = mysql_connect(’localhost’, ‘root’, ‘duygu’);
if (!$link) {
die(’Could not connect: ‘ . mysql_error());
}
echo ‘Connected successfully<br>’;if (!mysql_select_db(”test”,$link)) {
echo “Unable to select test: ” . mysql_error();
exit;
}
$sql = “SELECT * FROM myblog”;$result = mysql_query($sql);
if (!$result) {
echo “Could not successfully run query ($sql) from DB: ” . mysql_error();
exit;
}
if (mysql_num_rows($result) == 0) {
echo “No rows found, nothing to print so am exiting”;
exit;
}
while ($row = mysql_fetch_assoc($result)) {
echo $row["NAME"].” “;
echo $row["LASTNAME"].”<br>”;
}mysql_close($link);
?>
