Question

Here is a php function:

mysqli_stmt_bind_param($statement, "s", ...variable amount of parameters...);

It will accept a variable amount of parameters you can review the documentation here – php.net. Obviously I can’t type in $param1, $param2, $param3… because I don’t know many there will be. It is decided after run-time.

Answer 1

Since call_user_func_array() is using a callback as its first parameter, you can use any function you want. For example:

php > echo date('r', time());
Mon, 12 Sep 2011 00:37:52 +0300
php > echo call_user_func_array('date', array('r', time()));
Mon, 12 Sep 2011 00:38:23 +0300

So, you can call_user_func_array() as follows:

call_user_func_array('mysqli_stmt_bind_param', array_merge(array($statement, "s"), $params));
