This is a function I wrote to combine vsprintf and mysql_real_escape_string to return safe queries.
<?php
/**
* Returns safe database query.
* Usage: prepareQuery("SELECT * FROM x WHERE y = %d'", $id) // single argument
* Usage: prepareQuery("SELECT * FROM x WHERE y = %d AND z = '%s'", array($id,
$string)) // multiple arguments
* Usage: prepareQuery('SELECT * FROM x WHERE y = %2$d AND z = \'%1$s\'',
array($string, $id)); //argument swapping
* @see http://www.php.net/manual/en/function.sprintf.php
* @see http://www.php.net/manual/en/function.vsprintf.php
* @param string $sql String according to sprintf format
* @param mixed $values single value or array with values
* @return string safe query
*/
function prepareQuery($sql, $values = null)
{
// Convert single value to array
if ($values != null && !is_array($values))
$values = array($values);
if (count($values) > 0)
{
// Escape and replace values
$values = array_map('mysql_real_escape_string', $values);
$sql = vsprintf($sql, $values);
}
return $sql;
}
?>
