Description:
------------
The standard mysql_query function is very prone to abuse. Could a function be added that's safer? Like, for example:

mysql_query_safe("insert into T (A, B, C) values (?, ?, ?)", $a, $b, $c);

The function would be a bit like sprintf, except it would automatically call mysql_real_escape_string on all non-int arguments and enclose them in single quotes. Safe types like int would not receive this treatment.

Reproduce code:
---------------
mysql_query("insert into T (A, B, C) values (?, ?, ?)", $a, $b, $c);

Expected result:
----------------
No SQL injection vulnerability

Actual result:
--------------
SQL injection vulnerability

Sorry, but your problem does not imply a bug in PHP itself.  For a
list of more appropriate places to ask for help using PHP, please
visit http://www.php.net/support.php as this bug system is not the
appropriate forum for asking support questions.  Due to the volume
of reports we can not explain in detail here why your report is not
a bug.  The support channels will be able to provide an explanation
for you.

Thank you for your interest in PHP.

mysqli_prepare() already exists.

Guess why I used category: feature/change request. ;)

I'm aware of mysqli_prepare, but it's not what I requested, although the syntax might look similar.

mysqli_prepare is harder to use than mysql_query, instead of easier. That's no good...

SQL injections are still happening today and in a lot of cases PHP is involved. In 
my opinion it'd not be so hard to implement this feature request. It'd make a lot 
of people happy!
Could you reconsider?

Given the existence of both PDO and mysqli, I don't think anything Scott said 
three years ago has changed.

So mysql_query() is deprecated?
The mysql_query() page doesn't mention mysqli or PDO at all, wouldn't it be good 
to mention those if those are indeed the recommended way?
