[php] Get all mysql selected rows into an array

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);

You could try:

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

you can call mysql_fetch_array() for no_of_row time

$name=array(); 
while($result=mysql_fetch_array($res)) {
    $name[]=array('Id'=>$result['id']); 
    // here you want to fetch all 
    // records from table like this. 
    // then you should get the array 
    // from all rows into one array 
}

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

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