how to query once and display multiple times with where clause? - php

Question

I want to learn how to query once and display in multiple boxes with
where clause?
like :
if status 1 ? : display in <div class="1"> elseif status 2 ?: <div class="2"> etc. etc.
I know my answer is in my question and I need to do if statements, but I dont know how to display while loop or foreach a few times with same query.
Here is my query :
$stmt = $pdo->prepare("SELECT * FROM categories");
$stmt->execute();
while($row = $stmt->fetch()){
}
I have searched on google got a few examples like this with for loop but I didnt find any examples with where claus.
$i;
$stmt = $pdo->prepare("SELECT * FROM categories");
$stmt->execute();
while($row = $stmt->fetch()){
}
for($i=0; $i<5; $i++){
}
I tried if statment without foreach loop :
if($status == 1){
foreach(){
echo "Display box 1";
}
}
if($status == 2){
foreach(){
echo "Display box 2";
}
}
Displaying only one post need while loop or foreach to display all posts with status 1
Thanks

Answer 1

While you could buffer multiple streams, read the entire dataset into a PHP array and search it or run multiple queries, all are unnecessary and inefficient. Just sort the query. Consider:
$stmt = $pdo->prepare("SELECT * FROM categories ORDER BY status");
$stmt->execute();
$prevstatus=-1;
print "<div style='display:none'>";
while($row = $stmt->fetch()){
if ($row['status']!=$prevstatus) {
$prevstatus=$row['status'];
print "</div><div class='$prevstatus'>";
}
print ....
}
print "</div>";

I don't know if I understand your question but:
$stmt = $pdo->prepare("SELECT * FROM articles");
$stmt->execute();
while($row = $stmt->fetch()){
echo "<div class=\"class_". $row["status"] ."\">div content</div>\n";
}
And - CSS classes can not begin with numbers or have only numbers as a name! In my example I use .class_x (where X is your value from database)
