Request database_queryf() functions.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi All, After having been talking to lots of people in irc lately who are haveing problems with SQL injection etc i think that haveing a *_queryf() function would be really useful to help people esp when it comes to integers and the id=$id where $id = "1 OR" and name='$name' where $name = "name' OR" issues for example. Most of the sprintf formatting would take care of itself but any %s would automatically have addslashes() applied. I have a php implementation below for the mysql database. Let me know what you think or if i have missed anything. <?php /* ~ * MySQL queryf() function example. ~ */ define('DEBUG', true); // usage: // mysql_queryf($query, $link_identifier = NULL, $arg1, $arg2....$argN); function mysql_queryf() {

~    $args = func_get_args();
~    if(!isset($args[0]) || !(is_null($args[1]) || is_resource($args[1])

) ){

~        return false;
~    }

~    $formatString = array_shift($args);
~    $linkIdentifier = array_shift($args);

~    $parts = preg_split('/%([

0]|\'.)?-?[0-9]*(\\.[0-9]*)*[%abcdufosxX]/', $formatString, -1, PREG_SPLIT_OFFSET_CAPTURE);

~    $newString = "";
~    for($i = 0; $i < count($parts); $i++){
~        $start = $parts[$i][1] + strlen($parts[$i][0]);
~        if(isset($parts[$i + 1][1])){
~            $length = $parts[$i + 1][1] - $start;
~        }else{
~            $length = strlen($formatString) - $start;
~        }
~        $formatCode = substr($formatString, $start, $length);
~        $newString .= $parts[$i][0].sprintf($formatCode,

(isset($args[$i]) ? ((substr($formatCode, -1, 1) == 's') ? addslashes($args[$i]) : $args[$i]) : NULL));

~    }
~    if(DEBUG === true){
~        print("Query is:\n".$newString."\n");
~    }else{
~        if(is_resource($linkIdentifier)){
~            return mysql_query($newString, $linkIdentifier);
~        }else{
~            return mysql_query($newString);
~        }
~    }

} mysql_queryf('SELECT * FROM blah WHERE id=%d AND name=\'%\'.-34s\' AND account=\'%0.2f\' AND blah=%06d AND value > \'30%%\'', NULL, '1 OR', 'name\'s'); ?> Output: Query is: SELECT * FROM blah WHERE id=1 AND name='name\'s...........................' AND account='0.00' AND blah=000000 AND value > '30%' - -- Regards, William Bailey.
