PHP conflict with do-while end mysql_fetch_array? - php

Question

here's my code, there's something wrong, because when I put this in wamp (chrome), it returns me a duplicate "published by" (for any doubts, $conex = mysql_connect('localhost', 'root') )
<?php
mysql_select_db("spectrum-solaris",$conex);
$query = mysql_query("SELECT id,name,tittle,body FROM articles ORDER BY id DESC",$conex);
$row = mysql_num_rows($query);
if($row > 0 ){
do {
?>
<div class ="tematica" >
<p>
<small>Published by <b><?= $row['name'] ?></b></small>
</p>
<p>
<big><?= $row['tittle'] ?></big>
</p>
<p>
<b><?=$row['body']?></b>
</p>
</div>
<?php
}while($row = mysql_fetch_array($query));
}
mysql_free_result($query);
mysql_close($conex);
this is the result (the blue lines are made by me on PAINT):

Answer 1

do { } while() is not appropriate for a DB loop. On your FIRST past through the do. $row isn't going to be a DB result. It's going to be a simple integer - the number of rows in the result.
You want this instead:
$numrows = mysql_num_rows($query);
while($row = mysql_fetch_array($query)) {
...
}

Answer 2

Can you try this, instead of do { } while()
if($row > 0 ){
while($rowData = mysql_fetch_array($query)){
?>
<div class ="tematica" >
<p>
<small>Published by <b><?= $rowData['name'] ?></b></small>
</p>
<p>
<big><?= $rowData['tittle'] ?></big>
</p>
<p>
<b><?=$rowData['body']?></b>
</p>
</div>
<?php
}
}
mysql_free_result($query);
mysql_close($conex);

Answer 3

You don't fetch a row of your resultset on the first iteration... so $row doesn't contain datas on this first iteration.
You could try something like :
while ($row = mysql_fetch_assoc($query)){ // or mysql_fetch_array or ...
// ...
}
If you really want to use do{}while despite it's unsuitable for your use :
do {
$row = mysql_fetch_assoc($query); // or mysql_fetch_array or ...
// ...
} while ($row);
