Why I get only one row printed from my sql? - php

Question

There is two rows that should be printed from my sql.
id Symbol Shares
3 CSCO 40
3 FB 200
but this code prints only first row twice. Like this:
jharvard has 40 shares of CSCOjharvard has 40 shares of CSCO
Why?
Thanky you in an advance.
$users = query("SELECT * FROM users WHERE id = ?", $_SESSION["id"]);
$rows = query("SELECT * FROM stocks WHERE id = ?", $_SESSION["id"]);
$stock = $rows[0];
$username = $users[0];
foreach ($rows as $row)
{
if( $stock["id"] === $_SESSION["id"])
{
print("<td>" . $username["username"] . " has " . $stock["Shares"] . " shares of " . $stock["Symbol"] . "</td>");
}
}

Answer 1

The reason is your variables inside the loop
foreach ($rows as $row) {
if( $stock["id"] === $_SESSION["id"]) {
print("<td>" . $username["username"] . " has " . $stock["Shares"] . " shares of " . $stock["Symbol"] . "</td>");
}
}
You are printing the value of $stock, which earlier you defined:
$stock = $row[0];
So it will always output the data from the first row.
I suspect you want to change your loop as follows:
foreach ($rows as $row) {
// Changed from $stock['id'] to $row['id']
if( $row["id"] === $_SESSION["id"]) {
// Changed from $stock['Shares'] and ['Symbol'] to $row['Shares'] and ['Symbol']
print("<td>" . $username["username"] . " has " . $row["Shares"] . " shares of " . $row["Symbol"] . "</td>");
}
}
