I have this query for counting the number of items in a category:
SELECT category, COUNT(*) AS category_count FROM users GROUP BY category
Which creates results looking like:
category category_count
========== ================
X 3
Y 2
Now, In PHP I want to display the counts of the categories. For example, I might want to echo the count from category X, how would I do it?
Thanks in advance
Assuming $result holds the result of your query:
while ($row = mysql_fetch_array($result))
{
echo 'Category: ' . $row['category'];
if ($row['category'] == 'X')
{
echo ' Count: ' . $row['category_count'];
}
echo '<br/>';
}
$res = mysql_query("SELECT category, COUNT(*) AS category_count FROM users GROUP BY category");
while($row = mysql_fetch_assoc($res)){
echo $row['category'].": ".$row['category_count']."<br/>";
}
$result = mysql_query("SELECT category, COUNT(*) AS category_count FROM users GROUP BY category");
while ($row = mysql_fetch_array($result, MYSQL_NUM)) {
{
if ( $row['category'] == 'x' )
{
echo $row['category_count'];
}
}
while ($row = mysql_fetch_array($result))
{
echo 'Category: ' . $row['category'] . ' Count:' . $row['category_count'];
echo "<br>";
}
It would be better if you use the where clause in your query.
SELECT COUNT(*) AS category_count FROM users WHERE category = 'x'
$conn = mysql_connect("address","login","pas s");
mysql_select_db("database", $conn);
$Var = mysql_query("query");
While ($row = mysql_fetch_assoc($var) { echo $var["column"] }.
