Get all mysql selected rows into an array

Question

I am wondering if there a function in php that can allow me put all my selected data in an array .Currently i am using mysql_fetch_array and as i have read in the manual,that function won't fetch every record in the table.

$result = mysql_query("SELECT * FROM $tableName");            
$array = mysql_fetch_array($result);

  echo json_encode($array);

Answer 1

I would suggest the use of MySQLi or MySQL PDO for performance and security purposes, but to answer the question:

while($row = mysql_fetch_assoc($result)){
     $json[] = $row;
}

echo json_encode($json);

If you switched to MySQLi you could do:

$query = "SELECT * FROM table";
$result = mysqli_query($db, $query);

$json = mysqli_fetch_all ($result, MYSQLI_ASSOC);
echo json_encode($json );

Answer 2

1. Loop through the results and place each one in an array

2. use mysqli_fetch_all() to get them all at one time

Answer 3

You could try:

$rows = array();
while($row = mysql_fetch_array($result)){
  array_push($rows, $row);
}
echo json_encode($rows);
