Question

I would like to add results into array and print on screen.
Here’s my code and nothing is printing…could someone help me take a look.

include('config.php');

$con = mysql_connect($host, $username, $password);
if (!$con){
    die('Could not connect: ' . mysql_error());
}

mysql_select_db('members', $con) or die(mysql_error()) ;

$sql = "SELECT * FROM people where status like '%married%' "; 
$result = mysql_query($sql);

while($row = mysql_fetch_array($result)){
    $result_array[] = $row['id']; // <-------**here**             
}

return $result_array;       

echo($result_array);
mysql_close($con);

Answer 1

Firstly, change:

mysql_select_db(mtar, $con) or die(mysql_error());

To:

mysql_select_db('mtar', $con) or die(mysql_error());

Then remove return $result_array; – you don’t need it and when used outside of a function it just halts execution of the script.

Finally, change

echo($result_array);

to:

print_r($result_array);

EDIT: Some additional thoughts:

You don’t need parentheses around the argument to echo – it’s actually more efficient to leave them out: echo $var; is quicker than echo($var);

If you’re only ever going to use the id column, then don’t select the whole row: use SELECT id FROM instead of SELECT * FROM.

Are you sure you need the wildcards either side of “married”? You may well do (depends on what the possible values of status are), but you probably don’t. So

$sql = "SELECT id FROM people where status = 'married' "; 

May be better,
