¿Cómo hago eco de una tabla con los resultados combinados de dos consultas similares de dos bases de datos diferentes?

Editar:

Suponiendo que sus resultados sean así:

Escribir

number company    db1 Count
1      SuperCorp  5
2      SuperCorp  10

Informe

number company    db2 Count
2      SuperCorp  10
3      SuperCorp  20

Si desea mostrar una tabla como esta

number company    db1 Count db2 Count
1      SuperCorp  5         0
2      SuperCorp  10        10
3      SuperCorp  0         20

Debe fusionar los resultados de las dos consultas antes de imprimirlos en la pantalla. Esto es posible gracias a su columna 'número' que puede usarse como la clave de su matriz PHP.

También debe modificar sus consultas SQL para incluir una columna falsa que represente el recuento de la otra base de datos:

$sql1 = "SELECT num.number AS Number, com.name As company, count(*)   As \"db1 count\", 0   As \"db2 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";

$sql2 = "SELECT num.number AS Number, com.name AS company, COUNT(*) AS \"db2 Count\", 0   As \"db1 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";

Y luego combine los 2 resultados anteriores para mostrarlos, así:

$results = array();
while($row = $result1->fetch_assoc()) {
     //Adding all the 1st query results 
     $results[$row['number']] = $row;
}

while($row = $result2->fetch_assoc()) {
     if(! isset($results[$row['number']]) {
          //Mean's this row is not present in the 1st database, so add it
          $results[$row['number']] = $row;
     }else {
          //Just merging the db2 Count from the 2nd database since other fields are the same
          $results[$row['number']]['db2 Count'] = $row['db2 Count'];
     }         
}


if ($results) {
      echo"<TABLE><caption>Total Call Count Overview</caption><TR>
      <TH>Number</TH>
      <TH>Company</TH>
      <TH>db1 Count</TH>
      <TH>db2 Count</TH></TR>";

    foreach($results as $row) {
         echo"<TR><TD>". $row["number"]. "</TD>";
         echo"<TD>". $row["company"]. "</TD>";
         echo"<TD>". $row["db1 Count"]. "</TD>";
         echo"<TD>". $row["db2 Count"]. "</TD></TR>";
    }
    echo"</TABLE>";
} else {
     echo"0 Results";
}
