Function for putting all database table to an array

I have written a function to print database table to an array like this

$db_array=  
 Array(
    ID=>1,
    PARENTID =>1,
    TITLE => LIPSUM,
    TEXT =>LIPSUM
    )

My function is:

function dbToArray($table)
                        {
                          $allArrays =array();
                          $query = mysql_query("SELECT * FROM $table");
                          $dbRow = mysql_fetch_array($query);
                            for ($i=0; $i<count($dbRow)  ; $i++)
                                {
                                   $allArrays[$i] =  $dbRow; 
                                }
                            $txt .='<pre>';
                            $txt .= print_r($allArrays);
                           开发者_运维问答 $txt .= '</pre>';
                            return $txt;
                        }

Anything wrong in my function. Any help is appreciated about my problem. Thanks in advance

Seems like you are trying to print a table (not a database)

function printTable($table){
   $allRows = array();
   $query = mysql_query("SELECT * FROM $table");
   while($row = mysql_fetch_array($query)){
      $allArrays[] =  $row; 
   }
   $txt ='<pre>';
   $txt .= print_r($allRows, true);
   $txt .= '</pre>';

   echo $txt;

   return $txt;
}

(Edit: fixed missing second parameter in print_r)

Im not sure your function will get all the rows returned by the database. mysql_fetch_array() returns only one row. So the for loop is pretty pointless.

Instead you should something like this instead of the for loop.

while($row = mysql_fetch_array($query) {
  $allArrays[] = $row;
}

by the way if you still want to use the for loop you could try something like this. But what would be the point? the while loop works perfectly for this.

$numRows = mysql_num_rows($query);
for($i = 0; $i < $numRows; $i++) {
  $allArrays[$i] = mysql_fetch_array($query);
}

It looks like it'll work, but kind of defeats the purpose of a relational database.. Why not just serialize your data and write it to a file?
