Question

I have my array displayed like it but I cant seems to be able to save it into database. So when I do var_dump($result); while $result is my array then the following content is displayed

array
0 => 
array
  'Credit Weighting' => string '5' (length=1)
  'Teaching Period(s)' => string 'Teaching Periods 1 and 2.' (length=25)
  'No. of Students' => string '-.' (length=2)
1 => 
array
  'Credit Weighting' => string '5' (length=1)
  'Teaching Period(s)' => string 'Teaching Periods 1 and 2.' (length=25)
  'No. of Students' => string '-.' (length=2)
2 => 
array
  'Credit Weighting' => string '10' (length=2)
  'Teaching Period(s)' => string 'Teaching Periods 1 and 2.' (length=25)
  'No. of Students' => string '-.' (length=2)

And below is my PDO query to save the above content into mysql but nothing is happening.What am I doing wrong please ??

$result = array();  
$placeholder = array();
$values = "?, ?, ?";
foreach ($result as $array){
$placeholder[] = $value;

        $result[] = $array['CreditWeighting'];
        $result[] = $array['TeachingPeriod'];
        $result[] = $array['NoofStudents'];         
} 

$sql = "INSERT INTO data_array_copy (CreditWeighting,TeachingPeriod,NoofStudents)
                             VALUES (". implode('), (', $placeholder) . ")"; 
$stmt = $conn->prepare($sql);
$stmt->execute($result);

Ok just in case there is anyone out there that might need to know a easier way this could be done. Here is the solution that works well.

$result = array();  
foreach($result as $snode) { 

 foreach($snode as $key => &$val) {
  $val = mysql_real_escape_string($val);      
 }

$query = sprintf("INSERT INTO data_array_copy (
        CreditWeighting,
        TeachingPeriod,
        NoofStudents) 
                    VALUES ('%s')",implode("','",$snode));

mysql_query($query) or die (mysql_error());
echo $query. '<br />'; 
}

This works great !!
