Get a PHP Variable From the Bottm to the Top - php

Question

I am not sure how to do this. From the answer I've found on here, I think it's possible using jquery/ajax maybe. I need to get the value of my variable $i and echo it at the top, but it has to go through my logic to get to the value. Here is my code:
echo "<div id='records'><h1 align='center'>Today's Transfers (" . $i . ") </h1>
<table cellspacing='0' cellpadding='0'>
<tr>
<th>Customer Name</th><th>Phone Number</th><th>Disposition</th><th>User</th><th>Date Called</th>
</tr>
";
$i=0;
$sql = "SELECT * FROM vicidial_closer_log WHERE DATE(call_date) = DATE(NOW()) ORDER BY call_date DESC";
$result = mysqli_query($link, $sql, MYSQLI_STORE_RESULT);
while($row = $result->fetch_assoc()){
$i++;
$phone_number = $row['phone_number'];
$lead_id = $row['lead_id'];
$disposition = $row['status'];
...then echo those variable in my columns and rows...
}
echo "</table> </div>";
echo $i;
Maybe there is another way to write my code so the logic comes before I output everything? Not sure how to do that though since I'm using a mysql query.

Answer 1

You should get the number of rows from the result set and display those where the i is, since it is essentially the same thing.
$num_rows = mysql_num_rows($result);
Move your code above the echo statement:
$i=0;
$sql = "SELECT * FROM vicidial_closer_log WHERE DATE(call_date) = DATE(NOW()) ORDER BY call_date DESC";
$result = mysqli_query($link, $sql, MYSQLI_STORE_RESULT);
and add
$num_rows = mysql_num_rows($result);
echo "<div id='records'><h1 align='center'>Today's Transfers (" . $num_rows . ") </h1>
and use the rest of your code as before .. Might think about removing i if you don't need it for something else.

Answer 2

If $i is the total number of returned results, you could do:
echo mysqli_num_rows($result)
... and have your query executed at the top of the page.
This would ideally be all in a model and being set in a view by a controller however. That way you're separating the presentation from the functional logic.
I suggest you have a read about MVC:

Answer 3

Sure, you can just move the echo above your logic. But the best to do is to separate logic from presentation. You can create a class to handle this or maybe just another file, it depends on your needs.
$i=0;
$sql = "SELECT * FROM vicidial_closer_log WHERE DATE(call_date) = DATE(NOW()) ORDER BY call_date DESC";
$result = mysqli_query($link, $sql, MYSQLI_STORE_RESULT);
while($row = $result->fetch_assoc()){
$i++;
$phone_number = $row['phone_number'];
$lead_id = $row['lead_id'];
$disposition = $row['status'];
echo "<div id='records'><h1 align='center'>Today's Transfers (" . $i . ") </h1>
<table cellspacing='0' cellpadding='0'>
<tr>
<th>Customer Name</th><th>Phone Number</th><th>Disposition</th><th>User</th><th>Date Called</th>
</tr>";

Do your computations first, then display your data.
Horribly mangled example code:
$count = 0;
$output = '';
$res = mysqli_query("SELECT * FROM...");
while( $row = mysql_fetch($res) ) {
$output .= "<tr><td>..." . $row['somevar'] . "</td></tr>";
$count++;
}
echo "<h1>Yadda yadda $count</h1>";
echo "<table>";
echo $output
echo "</table>";
