PHP Loop Question? - php

Question

I have a php script that will loop until all the skill, exp and rating variables are displayed that the user entered into the database.
What I want is the following code to only display once and only if the variables are holding info and not empty. How can I do this. I hope I explained it okay.
I want this code displayed first.
echo '<div id="con">';
echo '<h2 id="s">Skills</h2>';
echo '<h2 id="exp">Exp</h2>';
echo '<h2 id="r">Rating</h2>';
Here is the full code.
<?php
$mysqli = new mysqli("localhost", "root", "", "sitename");
$dbc = mysqli_query($mysqli,"SELECT * FROM skills WHERE user_id='3'");
if (!$dbc) {
print mysqli_error();
}
echo '<div id="con">';
echo '<h2 id="s">Skills</h2>';
echo '<h2 id="exp">Exp</h2>';
echo '<h2 id="r">Rating</h2>';
while ($row = mysqli_fetch_assoc($dbc)) {
if (!empty($row['skill']) || !empty($row['exp']) || !empty($row['rating'])) {
if (! empty($row['skill'])) {
echo '<div class="s">';
echo '<p>' , htmlspecialchars($row['skill']) , '</p>';
}
if (! empty($row['exp'])) {
echo '<div class="s">';
echo '<p>' , htmlspecialchars($row['exp']) , '</p>';
}
if (! empty($row['rating'])) {
echo '<div class="s">';
echo '<p>' , htmlspecialchars($row['rating']) , '</p>';
}
}
}
echo '</div>';
?>

Answer 1

you can take the following after the loop:
echo '<div id="con">';
echo '<h2 id="s">Skills</h2>';
echo '<h2 id="exp">Exp</h2>';
echo '<h2 id="r">Rating</h2>';
and instead of echo in the loops , use vars to store the text and then check if the var holds something and then echo
update:
would become something like this:
$skills = "";
$exps = "";
$ratings = "";
while ($row = mysqli_fetch_assoc($dbc)) {
if (!empty($row['skill']) || !empty($row['exp']) || !empty($row['rating'])) {
if (! empty($row['skill'])) {
$skills .='<div class="s">';
$skills .= '<p>' , htmlspecialchars($row['skill']) , '</p>';
}
if (! empty($row['exp'])) {
$exps .= '<div class="s">';
$exps .= '<p>' , htmlspecialchars($row['exp']) , '</p>';
}
if (! empty($row['rating'])) {
$ratings .= '<div class="s">';
$ratings .= '<p>' , htmlspecialchars($row['rating']) , '</p>';
}
}
}
echo '<div id="con">';
if($skills){
echo '<h2 id="s">Skills</h2>';
echo $skills;
}
if($exps){
echo '<h2 id="exp">Exp</h2>';
echo $exps;
}
if($ratings){
echo '<h2 id="r">Rating</h2>';
echo $ratings;
}
echo '</div>';
