How do I echo a table with the combined results of two similar queries from two different databases? (using MySql/php) : I'm relatively new to coding so please bare with me with regards to this question!

I have two different (yet almost identical) databases and I and trying to produce a table which will display the combined results of a query on the two databases. 
(In MySql workbench, these databases are completely separate, and contain the databases that are being queried, I'm not sure if that makes a difference but it may be useful to know).

I need the results table to show the following:

number | company | db1 count | db2 count |

Number and Company are in both databases, the only difference between the two is that the count in one is different.

**Eventually there will be a fifth column, which will show the difference between the two counts, but I will get to that eventually.


I've looked at many different ideas with regards to getting the result I want, but I still have no idea really.
Where the number in db1 and db2 are the same, I need to display the count for each.
The code I have at the moment is:

    // Creating the connection
	$conn1 = new mysqli($servername, $username, $password, $db1);
	$conn2 = new mysqli($servername, $username, $password, $db2);
    	
	// Test connection
	if ($conn1->connect_error) {
		die ("Connection failed: " . $conn1->connect_error);
	} 
	elseif ($conn2->connect_error){
		die("Connection failed: " . $conn2->connect_error);
	}
	
    $sql1 = "SELECT num.number AS Number, com.name As company, count(*)   As db1 count 
    					FROM db1.db.job_processing AS jp
    					LEFT JOIN db1.db.number AS num ON num.id=jp.number_id 
    					LEFT JOIN db1.db.company AS com on com.id=num.company_id 
    					WHERE jp.show=1 AND jp.processing_complete=1 
    					AND jp.call_start_time BETWEEN '2016-12-17' AND '2017-01-03'
    					GROUP BY Number
    					ORDER BY Number
    					LIMIT 20";
    $result1 = $conn1->query($sql1);
    
    $sql2 = "SELECT num.number AS Number, com.name AS company, COUNT(*) AS db2 Count
    				FROM db2.db.job_processing AS jp
    				LEFT JOIN db2.db.number AS num ON num.id=jp.number_id 
    				LEFT JOIN db2.db.company AS com on com.id=num.company_id 
    				WHERE jp.show=1 AND jp.processing_complete=1 
    				AND jp.call_start_time BETWEEN '2016-12-17' AND '2017-01-03'
    				GROUP BY Number
    				LIMIT 20";
    $result2 = $conn2->query($sql2);
    
    
    if ($result1 = $conn1->query($sql1)) && ($results2 = $conn2->query($sql1)) {
    		echo"<TABLE><caption>Total Call Count Overview</caption><TR>
    		<TH>Number</TH>
    		<TH>Company</TH>
    		<TH>db1 Count</TH>
    		<TH>db2 Count</TH></TR>";
    
            //This is where I think my problems are arising
    		while ($row1 = $result1->fetch_assoc()) && ($row2 = $result2->fetch_assoc()) {
    			echo"<TR><TD>". $row1["number"]. "</TD>";
    			echo"<TD>". $row1["company"]. "</TD>";
    			echo"<TD>". $row1["db1 Count"]. "</TD>";
    			echo"<TD>". $row2["db2 Count"]. "</TD></TR>";
    		}
    			echo"</TABLE>";
    	} else {
    		echo"O Results";
    		}	
    
    	$conn1->close();
    	$conn2->close();

I think it's the end part where I am stuck. I have also looked at the following solution:

    
	if ($result1 = $conn1->query($sql1)) {
		echo"<TABLE><caption>Total Call Count Overview</caption><TR>
		<TH>Number</TH>
		<TH>Company</TH>
		<TH>db1 Count</TH>
		<TH>db2 Count</TH></TR>";

		while ($row1 = $result1->fetch_assoc()) {
			echo"<TR><TD>". $row1["number"]. "</TD>";
			echo"<TD>". $row1["company"]. "</TD>";
			echo"<TD>". $row1["db1 Count"]. "</TD>";
			echo"<TD>". $row2["db2 Count"]. "</TD></TR>";
		}
			echo"</TABLE>";
	} else {
		echo"O Results";
		}

	if ($result2 = $conn2->query($sql2)) {
		echo"<TABLE><caption>Total Call Count Overview</caption><TR>
		<TH>Number</TH>
		<TH>Company</TH>
		<TH>db1 Count</TH>
		<TH>db2 Count</TH></TR>";

		while ($row_devel = $result_devel->fetch_assoc()) {
			echo"<TR><TD>". $row1["number"]. "</TD>";
			echo"<TD>". $row1["company"]. "</TD>";
			echo"<TD>". $row1["db1 Count"]. "</TD>";
			echo"<TD>". $row2["db2 Count"]. "</TD></TR>";
		}
			echo"</TABLE>";
	} else {
		echo"O Results";
		}

Those are just two of the solutions I've been trying.
I just don't get how I can merge the two queries together, and I realise I have probably gone completely wrong in a number of places, but any assistance I could get would be much appreciated.
