Question

The database is fine but i can’t figure why $ROW cannot be recognized as NULL.

I have this code:

$pdo = new PDO("mysql:host=" . $this->hostname . ";dbname=" . $this->dbname, $this->username, $this->password);

foreach($pdo->query('SELECT * FROM people WHERE name="Joshua"') as $row):
    if($row['name'] != NULL):
        echo "WE HAVE ONE JOSHUA";
    else:
        echo "WE DO NOT HAVE ANY JOSHUA";
    endif;
endforeach;

When i run this script i got the: “WE HAVE ONE JOSHUA” message;

When i change name=”Joshua” in PDO->QUERY for a name that does not exist on database i do not receive the “WE DO NOT HAVE ANY JOSHUA” message;

Any hints to deal with this?

I just want to create a statement that control if the FOREACH return NULL or NOT.

Thanks in advance and sry the bad english.

Answer 1

how about this?

foreach($pdo->query('SELECT COUNT(*) totalCOunt FROM people WHERE name="Joshua"') as $row):
    if($row['totalCOunt'] != 0):
        echo "WE HAVE ONE JOSHUA";
    else:
        echo "WE DO NOT HAVE ANY JOSHUA";
    endif;
endforeach;
