使用PHP在HTML表格单元中输出MySQL查询

Question

I'm working in the IT department of my company and it is my responsibility to send daily reports of the calls registered in the Call Center department. I'm new with MySQL, PHP or HTML and I'm already facing my first problems.

My objective is to run some queries in PHP and then output them in a HTML table cell. Let me be more specific. I have access to a telephone record database and I need to count the number of total calls and lost calls of every branch daily. Right now I just run 2 queries in MySQL and then copy-paste them in a .xls table.

I have the right queries, I get the right result in mysql, even in PHP I get the result posted on the webpage (kind of), but I don't know how to create a table, or how to input the result of a query into a specific cell of the table.

Here's what I've got so far:

<?php

$conn=@mysql_connect('host', 'username', 'password', 'asteriskcdrdb.cdr');
echo ('total calls ROPCW: ');
$result=mysql_query('select count(*) from asteriskcdrdb.cdr where calldate like "2016-04-11%" and dst="020" and disposition="ANSWERED" and duration > "10" ');
echo mysql_result($result, 0);

mysql_close($conn);
?>

This code will post on my page the count of total calls made on 4.11.2016 like this: total calls ROPCW: 369

My objective is to create a table like this:

So the result of that query I mentioned above would go on the ROPCW->Total cell (where is 305) on the left side, on the right side are the monthly reports so far.

Answer 1

You can work out one big query or use a view to gather the data you need from a single source. Other suggestion would be, looping through all your branches and gather all the data you need, to build an associative array indexed similar to this:

$records[branch] = [date => [total => x, lost => y], mtd => [total => X, lost => Y]];

Then just do a:

foreach ($records as $branch => $record)
{
     echo string to build table row
}

Answer 2

I suggest use mysql_fetch_object or mysql_fetch_assoc functions instead of mysql_result. Basically because those functions fetch an entire row instead of one single cell value. For your example query works fine because your aggregate function returns only one cell and row. But for your desired output won't work. Keep in mind that you can inject HTML code within PHP and vice versa. Just do something like:

The idea would be run a select * from yourTable; Then,

$result = mysql_query($sql);
echo "<table>\n";
echo "<tr><th>Branch</th></tr>\n";
while ($callRecord = mysql_fetch_object($result)) {
    echo "<tr><td>{$callRecord->branch}</td></tr>\n";
}
echo "</tr>\n";
echo "</table>\n";

That should output a list of all tour branches. this is a guideline. Hope this helps!!

You can go to www.php.net and choose between mysql_fetch functions which one will work better for you.
