找出mysqli查询字符串

Question

short question, but apparently google nor php.net have no idea about this so I was curious if it is possible.

Can you get the query string of an mysqli element? I need it to make a proper error function

$mysqli = new mysqli(....);
$mysqli->query('INSERT INTO test(value) VALUES ('.rand(1,10000).');');
// here how do i find out the query of the $mysqli object WITHOUT having 
// to save it before (i.e. using the actual $mysqli object)

Thanks!

Answer 1

Judging from http://www.php.net/manual/en/class.mysqli-result.php - you can't.

$mysqli->query() is a method call, which returns mysqli_result object, and looking at the above manual page, it contains no record of the query that was just executed to create it.

Answer 2

Not sure I understand your question, but:

$sql = "INSERT INTO test(value) VALUES ('.rand(1,10000).');";
$mysqli->query($sql);

...then, later in your scirpt, you can just reference $sql :

if($sql = '...'){...}

Etc.
