Get query back from PDO prepared statement

Try $statement->queryString.

The simplest way to achieve what you want is:

$statement->debugDumpParams();

Just make sure you add it after executing the statement.

This procedure works. Since debugDumpParams() doesn't return the output. Here is a little trick i designed.

// get the output before debugDumpParams() get executed 
$before = ob_get_contents();

//start a new buffer
ob_start();

// dump params now
$smt->debugDumpParams();

// save the output in a new variable $data
$data = ob_get_contents();

// clean the output screen
ob_end_clean();

// display what was before debugDumpParams() got executed
printf("%s", $before);

$statement = "";

// Now for prepared statements
if (stristr($data, 'Sent SQL') !== false)
{

// begin extracting from "Sent SQL"
$begin = stristr($data, 'Sent SQL');

// get the first ] square bracket
$square = strpos($begin, "]");

// collect sql
$begin = substr($begin, $square + 1);
$ending = strpos($begin, "Params");

$sql = substr($begin, 0, $ending);
$sql = trim($sql);

  // sql statement here
  $statement = $sql;
}
else
{
  if (stristr($data, 'SQL') !== false)
  {
     $begin = stristr($data, 'SQL');
     // get the first ] square bracket
     $square = strpos($begin, "]");

     // collect sql
     $begin = substr($begin, $square + 1);
     $ending = strpos($begin, "Params");

     $sql = substr($begin, 0, $ending);
     $sql = trim($sql);

     $statement = $sql;
  }

}


// statement here
echo $statement;

Hope this helps.
