Getting the value of a string inside a variable

I’m trying to get the value of a string inside a variable
$sql = ‘SELECT * FROM table1 WHERE field1 = “value”‘;
$result = $con->query($sql);
while($row = $result->fetch_array(MYSQL_ASSOC)){
$value = $row[‘field2’];
var_dump($value);
}

If I var_dump $row[‘field2’] it returns the right value, but I cannot seem to get the value. I always get NULL.
If I do echo $value; it prints NULL.
How can I get the value?

Use the $result->fetch_assoc() function to return an array of your results.
This will fetch and return the data from the database in the most efficient way.
This is how it works:

If you want to use PHP:
$result->fetch_assoc();
while($row = $result->fetch_array(MYSQL_ASSOC)){
$value = $row[‘field2’];
}
