如何在 php 中将 sql 查询的结果输出到屏幕上

Question

The following is the code I use to try and achieve this.

$con=mysqli_connect("localhost:8889","root","root","booksmart_properties");
    // Check connection
    if (mysqli_connect_errno())
      {
      echo "Failed to connect to MySQL: " . mysqli_connect_error();
      }
    else{

        echo "we connected";
    }

    // Perform queries 
    $sql=mysqli_query($con,"SELECT * FROM ListedProperties");
    $result=mysqli_fetch_assoc($sql);



    echo $result['*'];


    mysqli_close($con);

?>

I'm new to php and i'm sure it's something small, I just can't see it.

Answer 1

Use PHP foreach loop like this:

foreach($result as $key => $val)
{
     print $val;
}

Answer 2

You are using

$result = mysqli_fetch_assoc($sql);

which will fetch a result row as an associative array

So you can call your result with a key to get a value.

example:

$result['id']

or to get all:

foreach($result as $key => $value)
{
    print $value;
}
