Hello everyone i have some question about query on mysql.
I have some code like this
SELECT site.id, site.name_site, site.id_site,site.id_mast,site.address,site.types,
site.longtitude,site.latitude,site.altitude, site.id_region as site,
region.name_region, region.id_region as region
FROM site as site
INNER JOIN region as region
ON site.id_region = region.id_region ORDER BY name_site limit 3;
And also this work:
SELECT * FROM site, region WHERE site.id_region= region.id_region LIMIT 2;
On browser nothing happen, byt on mysql this work, but not on PHP. Why i have some mistake on script php or have problem with query mysql?
Please help me.
Thanks for all hints.

try to remove the simple quotes in your printf: $row['id_region'] becames $row[id_region] but I suggest you this to be sure:
echo '<td>'.$row['id_region'].'</td>';
Also, please consider using mysqli instead of mysql, as it's deprecated
<?php
$dbhost = '............';
$dbuser = '........';
$dbpass = '.......';
$dbname = 'db_site';
$my = new Mysqli($dbhost, $dbuser, $dbpass, $dbname);
?>

<table border='2' cellspacing='0' cellpadding='0'>
<tr>
<td>id</td>
<td>id_site</td>
<td>id_mast</td>
<td>name_site</td>
<td>address</td>
<td>types</td>
<td>longtitude</td>
<td>latitude</td>
<td>altitude</td>
<td>id_region</td>
</tr>
<?php
// create a db connexion
$sql = 'SELECT * FROM site, region WHERE site.id_region= region.id_region LIMIT 2;';
// make the query
$stmt = $my->query($sql);
// fetch the results, display them as you want
while($row = $stmt->fetch_assoc())
{
echo '<tr>';
echo '<td>'.$row['id'].'</td>';
echo '<td>'.$row['id_site'].'</td>';
echo '<td>'.$row['id_mast'].'</td>';
echo '<td>'.$row['name_site'].'</td>';
echo '<td style="width:100;">'.$row['address'].'</td>';
echo '<td style="width:100;">'.$row['types'].'</td>';
echo '<td>'.$row['longtitude'].'</td>';
echo '<td>'.$row['latitude'].'</td>';
echo '<td>'.$row['altitude'].'</td>';
echo '<td>'.$row['id_region'].'</td>';
echo '</tr>';
}
echo '</table>';
