Question

I have some code that works, but is clunky and am wondering if there is a better way to do it, first the code, and then i will explain:

// repeat query 10 times
for ($i = 1; $i <= 10; $i++) {
   $query = @mysql_query("SELECT fileName FROM images");
    while($row = mysql_fetch_assoc($query)){
        extract($row);
        echo "<img src='images/images/$fileName'/>";
    }
}

I would like to repeat a set of images whose file names are stored in a mySql table. The code above repeats the query 10 times. I would rather query once, then repeat the list. Is there a way to do this, either on the mySql side or in the php loop?

Thanks.

Answer 1

Cache all the rows from the query in an array. Loop through the cache array 10 times and print.

$a= array();
$query= mysql_query("SELECT fileName FROM images");
while($row = mysql_fetch_assoc($query))
 $a[]= $row;

for ($i = 1; $i <= 10; $i++) {
 foreach ($a as $row)
   echo "<img src='images/images/{$row['fileName']}'/>";
}

Of course you’ll need to sanitize the output of $row['fileName']
