And to prevent SQL injection I suggest<div><br></div><div><div>$comma_separated = implode(&quot;,&quot;, $array_of_uids);</div><div><b>array_walk($comma_separated, &#39;mysqli_real_escape_string&#39;, $mysqli_link_object);</b></div>
<div>$sql = <span style="font-family: arial, sans-serif; font-size: 13px; border-collapse: collapse; ">&quot;UPDATE products SET product_price = &#39;7.6&#39; WHERE id IN ($comma_separated)&quot;;</span></div><br><div class="gmail_quote">

Let me add to Gregory&#39;s explanation...you can save on cpu cycles by making one sql query to update all rows. Instead of a loop on the sql queries you can loop on the array_of_uids variable and create a comma delimited string out of them e.g. in PHP you can easily use the implode function:<div>


<br></div><div>$comma_separated = implode(&quot;,&quot;, $array_of_uids);</div><div>$sql = <span style="font-family:arial, sans-serif;font-size:13px;border-collapse:collapse">&quot;UPDATE products SET product_price = &#39;7.6&#39; WHERE id IN ($comma_separated)&quot;;</span></div>


<div><div><br></div></div><div>HTH</div>
