Question

I’m trying to get results from a MySQL database (for invoices) that includes multiple rows with multiple columns in each row. The database has three columns: Date (text), Hours (text), and Charged (boolean). I am trying to get an array of arrays to feed into a PHP script where the final product would be the same as this:

$invoice = array(array("date1","hours1"),array("date2","hours2"));

I currently have the following code:

$con = mysql_connect("$host", "$username", "$password");
$condb = mysql_select_db("$db_name");
...
120 | $sql = "SELECT date,hours FROM 'c1_log' WHERE charged=0";
121 | $result = mysql_query($sql,$con);
122 | $invoice = mysql_fetch_array($result);

When I run the code I get the following PHP error:

Warning: mysql_fetch_array(): supplied argument is not a valid MySQL result resource in .../dbcon.php on line 122

Is there an alternate function to mysql_fetch_array() that would work?

I don’t think there is a fetch_all function for mysql you need to get it programmatically:

$con = mysql_connect("$host", "$username", "$password");
if ( ! mysql_select_db("$db_name")) {
  echo "Could not select DB: " . mysql_error();
  exit;
}

$sql = "SELECT date,hours FROM `c1_log` WHERE charged=0";

if ( ! ($result = mysql_query($sql,$con) ){
  echo "Query error: " . mysql_error();
  exit;
}

// use fetch_assoc so that you end up with array
// keys as the column names not numbers
while ($invoice[] = mysql_fetch_assoc($result));

//While loop is used to get all results from the query into an array.


//To check your output:
// (if in a browser echo a pre tag for nice formatting)
echo "<pre>";
print_r($invoice);
echo "</pre>";

//Should give you something like this..
//$invoice = array(0=>array("date"=>"","hours"=>""),1=>array("date"=>"","hours"=>""));
