如何在PHP中获取对象数组的记录数

Question

I'm trying to display the total number of records returned from my mongo 3.4 database. For this particular query, the results should be 380 but it's showing 14489. I'm sure it's something simple that I'm missing / forgetting about PHP

Here's the code: (including some debug statements about the type of variable I'm dealing with)

       $numrecords = count($records);                                
       echo"<BR><font color=red>".gettype($records)."</font>";
       echo"<BR><font color=red>".sizeof($records)."</font>";
       if (  $numrecords > 0 ) {
              echo "<tr><td colspan='5'><h3>Record Count: ".$numrecords ."</h3></td></tr>";
              echo "<tr><th>PH Number</th><th>Department</th></tr>";
              foreach ( $records as $rec ) {
                     if (!empty($rec->department)) {                                                                                          
                         echo "<tr>";
                         echo "<td>". $rec->phnum . "</td>";
                         echo "<td>". $rec->department . "</td>";
                         echo "</tr>";
                     }   
              } //end for 
       } else {
              echo "<tr><td colspan='5'>No matching data</td></tr>";                                  
       } 

It says the object type is 'array'. I've been playing with count() vs. sizeof()

Any tips would be appreciated.

Answer 1

So it shows the correct number of rows in the table, but the count shows more than what's in the displayed table?

Try to use msqli_num_rows after your query

Here's an example below, you'll have to change it to your needs since you didn't provide your query code

$sql = "SELECT * FROM table_name WHERE datarow='$datarow'";
$result = mysqli_query($conn, $sql);
//this is where you count the number of rows returned from this query.
$count = mysqli_num_rows($result);

If this doesn't work, there's a problem with your query not meeting the specifications that you desire.
