Question

I am writing a simple php registration page using MySQL as the database. I am quite new to it and I came across this error:

Parse error: syntax error, unexpected
T_ENCAPSED_AND_WHITESPACE, expecting
T_STRING or T_VARIABLE or T_NUM_STRING
in C:\xampp\htdocs\w4wregister.php on
line 34

I have gone through the little bit of code that I added that caused that error for the past hour and cannot see anything wrong with it. Below I have the code I added. I believe I was able to narrow it down to the while statement but I gave the other code for context.

if($r) {

echo "<h1>Thanks for registering!<h1><br/><h2>Current Users:</h2>";

$q2 = "SELECT username AS users FROM users ORDER BY registration_date";

$r2 = @mysqli_query ($dbc, $q2); //gets all users

if ($r2) {

echo '<table cellspacing="3" cellpadding="3" width="25%"><tr><td>Username</td></tr>';


while ($row = mysqli_fetch_array($r2, MYSQLI_ASSOC)) {

echo "<tr><td> $row['users'] </td></tr>";

}

echo "</table>";

} else {

echo "Hey, that didn't work!";
}

Answer 1

Change:

echo "<tr><td> $row['users'] </td></tr>";

To:

echo "<tr><td> {$row['users']} </td></tr>";

Another option would be:

echo "<tr><td> ".$row['users']." </td></tr>";

Or even:

echo "<tr><td> ", $row['users'], " </td></tr>";

See the echo for more examples of how to employ variable interpolation.
